Introduction

Dear customer,

The manuals of component manufacturers
such as the brake manufacturer, the gear sys­tem manufacturer,and the pedal manufacturer
also belong to this manual. They give detailed
information on operating and maintaining
these specific parts. Please read the manuals of
the part manufacturers as carefully as this
manual.Please provide this manual to any oth­er user of your recumbent before using it.

The maintenance and adjustment of this re­cumbent partly requires special tools and
skills.Do only works within your limits and,
for the purpose of your own safety,do not go
beyond.Should you be uncertain at any point,
get in contact with your local dealer.

The instructions in this manual apply only to a
completely assembled Scorpion fs 26 with
standard parts from the series production of
HP V

ELOTECHNIK.

On special demand HP V

ELOTECHNIK delivers

frame kits to put a specialist dealer in a posi­tion to assemble a tricycle individually. In this
case the manuals on the operation and mainte­nance of the parts only represent a guideline,
please read every manual of every part manu­facturer separately.The specialist dealer is re­sponsible for the expert assembly, please con­tact him for detailed information! A tricycle
that has been assembled from a frame kit must
always be tested and approved by a qualified
bicycle mechanic before your first ride.

General safety instructions

Intended use

Your Scorpion fs 26 is a tricycle for the use on
streets and paved roads.

This tricycle is not designed for the use in rac­ing and off-road riding,for jumping or acrobat­ics,and you must not ride across curbs,stairs,
etc.

Damage through inappropriate use, assembly
errors,accidents or similar activities and wilful
damage results in the loss of any warranty.

The intended use also includes the precise ob­servation of the prescribed usage and mainte­nance regulations and instructions.

The first miles

The first 300 km (186 miles) are an important
for breaking in the tricycle.During the first use
of a new tricycle the screws may settle and
become loose. Cables and spokes may stretch.
Bearings may show play.Please be very atten­tive during that period.

After 300 km or after two months at the lat­est you will have to take your tricycle to a bi­cycle mechanic for the first service. Please
record this first service and the works per­formed in the warranty pass on page 65.This
first service is the prerequisite for further use
of the tricycle and for your warranty claims.

Load capacity

It is important to adjust the spring stiffness of
the suspension according to the load,see the
chapter about adjusting the suspension in this
manual,page 17.

The maximum load (rider + luggage) is 140 kg
(308 lbs). The maximum total weight (bicycle +
rider + luggage) is 160 kg (352 lbs). The lower
limit is valid. With an attached trailer,the maxi­mum total weight must not be higher than 160
kg (352 lbs).

The permitted axle load is 100 kg (220 lbs) on
the front axle and 95 kg (209 lbs) on the rear
axle.

Carrying luggage

Luggage transport is only allowed on the spe­cial racks designed by HP VELOTECHNIK .

The maximum load on the rear rack is 25 kg
(55 lbs).

When a rear rack is mounted you have to
make sure that when the rear suspension is
fully compressed there is at least a 1 cm (

1

/3")

distance between the rear tire or mudguard
and the rear rack.If you want to increase this
distance you have to decrease the suspension
travel of the rear suspension element with
clip-on spacers.For that purpose please con­sult your local dealer.

Additional loading can influence the handling of
your trike considerably. If you plan on riding
with heavy luggage we advise you to make a
test ride on a street with no traffic to get used
to the new situation.

HP

Velotechnik

The load should be placed as close to the
body of the rider as possible, since this results
in better riding performance. You can also im­prove the handling of the trike by positioning
the center of gravity of the luggage as low as
possible, so pack heavy items in the bottom of
your panniers.

Take care that your luggage is safely stored on
the racks.Bags must be tightly fastened to the
racks so they can not move.Make sure that
loose parts like straps or belts can not touch
the wheels,the derailleur, or the suspension.

The rear rack is designed for standard bike
panniers.

Take care that your luggage does not cover
the lighting system and the reflectors of your
tricycle and that they stay fully functional.

Transport in the car

The best way to transport your tricycle is in­side the car.Take care that it does not lie on
the derailleur.

If you want to transport it outside the car we
recommend a roof-rack or a rear carrier.Take
care to fasten your tricycle at the frame only.

Please remove any par ts that could come
loose during transport (seat cushion, water
bottles,luggage bags, pumps, pennants,etc.).

Final assembly

Your trike has been delivered to your special­ist dealer only partly assembled.

Your dealer has carefully finished the assembly,
perhaps altered the specification of your trike
to meet your special requirements and per­formed a test ride. Please make sure that this
pre-delivery service is recorded in the
Warranty Pass at the end of this manual.

All screws must be checked and tightened, es­pecially on the handlebar, stem, knuckles,swing
arm pivot and wheels.Please follow the tight­ening torque settings listed in the table on
page 63.

Derailleurs and brakes must be checked and
adjusted.Please follow the instructions in the
manuals of the parts manufacturers that come
with this manual.

Screws and bolts

Caution! Screws must be tightened with

prescribed tightening torque.In this manual
tightening torques are given in "Nm“
(Newtonmeter).Always use a torque
wrench wherever a torque setting is given in
this manual.Never rely on "feeling".Screws
tightened too much or not enough can
break,which can lead to dangerous acci­dents.In case you don't own a torque
wrench have your bicycle mechanic do the
respective work.You will find a table with
the prescribed torque settings on page 63 in
this manual.

Added parts and accessories

Additional accessories may impair the function
of your Scorpion fs 26. We advise you to gen­erally ask your dealer before you mount any
special parts or accessories to your tricycle.

Take care that the handlebar and the suspen­sion always stay moveable. You must not add
any parts to the handlebar or the seat that
might endanger the rider through sharp edged
or pointed shapes while steering,getting on
and off the trike or bumping against some­thing.

Before you purchase a bell or a lighting system
make sure that these accessories conform to
your national laws and regulations.

Fairings

As a front fairing for the Scorpion fs 26,you
may use the Streamer fairing offered by HP
V

ELOTECHNIK.Please take care to assure a good

vision over the fairing and sufficient freedom
of movement below.

Please take into account that any fairing makes
the tricycle more prone to crosswind influ­ences.In strong wind or gusts of wind unsafe
situations may occur.Please remove the fairing
before riding in such weather conditions.

Caution! Mounting additional parts or ac­cessories is at your own risk.It is important
that you carefully read the installation guide
of the manufacturer.Additions to the handle­bar like fairings,handlebar fittings,bottle
holders,etc. may impair your safety due to
additional loading or clips with sharp edges.

The situation described below is valid for
Germany only. For legal requirements in your
country,please contact the authorities.

Legal requirements

According to law, the Scorpion fs 26 is not a
bike but a motor vehicle class L2E (three­wheeled small motorcycles with a maximum
construction speed up till 45 km/h). The con­struction speed,that is the speed that the ve­hicle will reach without using muscle power, is
20 km/h. With additional power from the rid­er’s muscles, up till 45 km/h can be reached.At
that speed,the motor assistance is switched of
completely.

To be allowed to use the S-Pedelec on public
roads,there must be a operating licence for it
and it must be equipped with a insurance
plate.The operating licence is provided by HP
Velotechnik together with the vehicle and
needs to be handed out to the customer by
the dealer.The keeper of the Scorpion fs 26
must contract a motor vehicle liability insur­ance and will receive an insurance plate in do­ing so.

The operating licence already assures that the
S-Pedelec meets all legal requirements for tak­ing part in public traffic.The rider always has
to carry the operating licence while riding.

By the time this manual was edited the follow­ing regulations apply in Germany:You need to
have a driving licence class M (ever yone born
after 01.04.1965).It is not allowed to use bicy­cle lanes in towns/villages.You have to wear a
proper helmet.

Please inform about present regulations in
your country regarding driving licences,the
use of bicycle lanes,riding on paths away from
the road,wearing helmets etc.frequently.

Adjusting your new trike

9

Before the first ride:adjusting your
new Scorpion fs 26

Your position on the Scorpion fs26 is essential
for your riding comfort,well-being and effi­cient cycling. Therefore you should adjust the
frame, seat, handlebar and suspension to your
individual requirements.

In order to adapt the Scorpion as closely as
possible to your body dimensions and to find
your ideal position you need to adjust the
front boom,seat and handlebars.

If your trike is equipped with the optional
front boom-quickadjust,please read the in­structions in the seperate manual in addition
to the following instructions.

Adjusting the leg length: moving the
front boom

In order to adjust the leg length you have to
move the front boom (the front par t of the
frame where the cranks are mounted) in the
main frame. Unscrew the bolts M8x35 under
the main tube with a 6 mm Allen key.Take a
grip on the front derailleur tube or both
cranks and move the front boom further into
the frame or pull it out while cautiously turn­ing it.

Before you pull out the front boom shift the
chain to the smallest chain ring and sprocket.
Turn the cranks a little bit backwards while
pulling. Thus the chain is not under tension.

Adjusting the leg length

Danger!All procedures described here re-

quire a certain degree of skill,suitable tools
and mechanical aptitude.After any adjust­ment perform a static check and take a test
ride on a quiet street,away from traffic. If
you have any doubts please contact your lo­cal dealer.

Caution! After you have unscrewed the
clamping bolts take them off and examine
them for deformation.Lubricate threads and
heads thoroughly.Then re-fit the bolts.If
they don't turn easily you will have to re­place the bolts.

Unscrew the clamping bolts to adjust the front boom.

HP

Velotechnik

Adjust the front boom in a way that your leg
is fully extended when your heel (wearing flat
shoes) is in the foremost position on the ped­al.Experience shows that the pedal-to-seat
distance on a recumbent can be slightly longer
than on a conventional bike.

While you are pedaling,the ball of your foot
should be positioned above the center of the
pedal axle.

It is important that your leg is not fully
straightened when the crank is in the foremost
position.If the distance is too long it is difficult
to overcome this dead point,pedaling be­comes uncomfortable and there is too much
strain on the sinews of your feet and legs.If
the distance is too short you may suffer from
knee pain.

For riders with short leg length the front
boom has to be cut by a bicycle mechanic, so
it can be inserted maximum possible. It is im­portant to trim the end of the tube neatly.The
bare metal of the shortened tube end has to
be protected against corrosion with a paint
stick or wax spray.

The maximum insertion of the front boom is
limited by possible heel strike of the frame’s
cross bar,depending on the rider’s shoe size.
Please check before riding your trike that
there is enough heel clearance.For shorter
riders under 175 cm body height we recom­mend to use shorter cranks.

On the left underside of the front boom there
is a fine line.Align this line with the sticker on
the main tube’s front end right above the
clamping bolts to adjust the bottom bracket
axle to a horizontal position.Additionally, you
can look beyond the bottom bracket shell at
the rear wheel axle and align the front boom
parallel to it.Align your eyes with the bottom
bracket axle and not the front derailleur tube.
Then sit down on your tricycle and check the
position.

Tighten the bolts with a torque wrench (tight­ening torque 14–16 Nm).On your first ride
check whether there is sufficient clamping.

Adjusting the leg length

Adjust the front boon so that your knee will not be fully straight­ened when pedaling.

Danger!When you insert the front boom,
the front boom and the inner wall of the
tube must be totally free from grease,other­wise it will not clamp properly and may turn
while you are riding.

Caution! When you move the front boom
take care that its end does not damage any
light cables that possibly come out of the
main frame. Please inform yourself about the
length of the front boom on your trike be­fore you do any work.While moving the
front boom you also have to move the light
cables The light cable must never be
stressed by pulling.

Danger! If the bolts are tightened too
much or bent,the screw or the frame can
break! If the clamping is insufficient the front
boom can turn during a ride which may
cause your feet to slip from the pedals and
lead to injuries.

Caution!The minimum insertion depth of
the front boom into the main frame is 8 cm
(3 1/5"). The end of the front boom must
not be visible in the clamping slot when you
look at the main frame from below, since
this may result in a damage of the frame.

The rear end of the front boon must never be visible in the
clamping slot.

Danger! There must be a bushing (a slotted
tube of plastic with edges to the front and
the clamping slot) in the main frame’s front
boom hole that is glued in the frame.This
bush ensures safe clamping of the front
boom and protects the paint.It is important
to take care that this bush is always visible
at the front end of the main frame. The low­er slot has to be aligned in coincidence with
the slot in the main frame. If this bush is
missing or moved to the back of the tube
while inserting the front boom,safe clamping
is no longer guaranteed,even if it seems to
be the case at first glance. If the front boom
is not clamped properly it may turn and lead
to a fall.A missing or misaligned bush will
lead to frame damage.

The plastic bush between front boom and main frame must be
visible at all time.

If the bush is missing or not alligned properly or the screws are
tightened too much, the frame can break.!

After moving the bottom bracket tube your
dealer has to adjust the chain length.By default
the Scorpion fs 26 comes with a very long
chain so the adjustment range of the tricycle
can be fully used without the need to lengthen
the chain.

After the basic adjustment of the leg length
done by your dealer before handing over the
tricycle, the chain has to be shor tened so that
the derailleur cage is not fully turned forward
while shifting on the largest chain ring in front
and the smallest sprocket behind.The de­railleur must still be able to compensate a
length change of the chain of at least 4 cm (1
1/2").In order to choose the right chain
length,please consult the manual of the de­railleur manufacturer.

After adjusting the front boom the gap in the
clamping slot between the front boom and the
main frame should be sealed with wax or sili­cone in order to protect your frame from the
penetration of water and dirt and hence dam­age through corrosion which may lead to a
broken frame.

We recommend to slightly readjust the front
boom every 3 months so that knees in order
to provide a slightly different position to your
muscles and ankles.You might also find a more
comfortable and more efficient riding position.

A wrong adjustment may lead to pain in your
knees and inefficient pedaling.In addition we
recommend to ride with a high pedalling ca­dence, which means to pedal fast and with lit­tle pressure.Pedalling with too much pressure
may also lead to pain in the knees.You will find
more information about this on page 26.

Adjusting the leg length

Check that there is at least a 5 cm (2") clearance between the
end of the chain tube and other parts of the dr ive train.

Danger!After the chain has been short­ened it must be closed with a special closing
link or a chain riveting tool that expands the
rivet while riveting (i.e.R

OHLOFF- Revolver).

A poorly joined chain may break and thus
lead to damage or injury.Chain length ad­justments or chain changes should be done
by your bicycle mechanic.

Caution!Take care that the chain tubes
have a clearance of at least 5 cm (2") to the
rear derailleur and the front derailleur even
under maximum tension of the chain and
make sure that the tubes are held tight in
their fastenings. The front upper tube can be
moved to the rear for length adjustment.
Shorten the tubes if necessary.If the end of
the chain tube gets in touch with the rotat­ing chain rings it can be locked-up and de­stroyed. The chain tubes must be prevented
from moving by a rubber tube over the re­tention spring.

Adjusting the seat length

Your Scorpion fs 26 is equipped either with
the ErgoMesh

®

mesh seat or the adjustable

BodyLink

®

seat from HP VELOTECHNIK.

The following instructions refer to the
BodyLink seat.Length, seat back angle and
lower seat angle are adjustable for this seat.
The adjustment of the seat length and the
proper seat angle is crucial for a comfortable
feeling while riding your recumbent.

The upper curve of the seat back in the area
of the shoulder blades determines the correct
seat length: Through this shape the shoulder
and neck area is lifted from the recumbent po­sition so that the head rests in a natural and
relaxed position.For this reason you shouldn't
need a head rest if you have the right seat po­sition.On long rides, a head rest can increase
your riding comfort as you can relax your
neck for a few seconds by leaning back.You
can mount our custom headrest to your exist­ing seat.
The seat is too small when you have the im­pression that your back is pressed too much
into a "hunchback".It is too large when you
have the impression that the seat angle is too
far back when you are in the most upright po­sition,or when you hit the upper seat edge
with the back of your head when you look up­wards.

Adjusting the seat length

Take off the seat cover (see page 57).Open
the quick release lever for the seat back angle
adjustment,so that the seat is not bent with
inner tension.Loosen the 4 screws at the in­ner side of the seat back with an allen key
SW4 a few turns.Step behind your trike and
hold the seat back with both hands.Pull or
push the seat back to achieve the preferred
seat length. To achieve the smallest possible
seat length,move the 2 upper screws from the
top to the middle holes.

Tighten all 4 screws with 5–6 Nm.Move the
seat back rest to the preferred angle and close
the quick release lever firmly. Reinstall the seat
cover

Length adjustment of the

Airflow cushion

The optional Airflow-cushion consits of two
parts, that connect in a V-type shape. Loosen
the velcro mounting of the upper part,and
place it in the desired position,than fasten the
velcro.

Adjusting the seat back angle

A great advantage of the BodyLink® seat on
your Scorpion fs 26 is the possibility to adjust
the seat back angle very quickly. For beginners
or rides in the city you can choose an upright
seat position for a better view, and for longer
rides you can choose a flat position for better
aerodynamics.

The seat back is fastened with a quick release
lever on a slotted aluminum seat mounting.You
can adjust the seat back angle by 10 degrees
by simply opening the quick release lever.In
the medium seat position the angle is about
35° from horizontal.

Adjusting the seat position

Caution! Do not loosen or tighten the 4

screws in the lower seat part to adjust the
seat length.Maximum tightening torque of
these screws is 3–4 Nm.

Caution!To avoid noise from the seat when
loaded,the contact surfaces between the
two seat shells need to be seperated by self­adhesive plastic sheets and all contact sur­faces of seat and seat mountings and frame
need to be lubricated with grease.

Adjusting the seat back angle is easy when you
push the seat back with your hands on the
backside close to the seat mounting into the
desired position.By pulling at the upper seat
edge, tension may be created which causes the
adjustment mechanism to lock up.

Because of the flexibility of the BodyLink

®

seat
and the special shape of the seat mountings,
the seat effectively pivots around a central ax­is,approximately in the area of the lower lum­bar vertebrae.This is the place where you sup­port most of your pedaling force while riding,
so this point determines the distance to the
pedals. The advantage of this design is that you
adjust the distance from the seat to the bot­tom bracket only once as described above , a
change in the seat angle does not require an
adjustment of the front boom.

Adjusting the front seat edge

The front seat edge can be slightly lowered to
accommodate smaller riders. With a lower
front seat edge,it is easier to put your feet on
the ground without pressure from the seat
edge on the back of your legs. With a higher
front seat edge,the seat will give more sup­port and avoid the feeling of „sliding down the
seat“ that occurs with upright seat angles.

To adjust the front seat edge,open the quick
release lever at both the lower and the upper
seat half,so that the seat is not under inner
tension. Thus you need less force for the ad­justment.Push or pull the seat front edge firm­ly to reach the desired position and close the
quick release lever firmly.Then adjust the seat
back angle as described above.

If the quick release lever pressure is to loose
when closed,open the lever and turn the
screw on the end of the quick release axle
clockwise.The low profile design of the screw
head gives more clearance for the drive train.

Adjusting the lumbar support

The BodyLink®seat is ergonomically shaped
and supports the natural S-curve of your
spine. Forces from pedaling are supported in
the area of your lower back just above your
hips. The amount of suppor t in this area (lum­bar support) is adjustable by moving the seat
back and lower seat against each other.

To get more lumbar support,lower the seat
front edge and put the seat back in a more re­clined position.
To get less lumbar support,rise the front seat
edge and put the seat back more upright.
For maximum adjustment,loosen the 4 screws
for the seat length adjustment in the seat back.
Thus the lobes of the lower seat part can
move more easily into the desired shape.
Tighten the screws and quick releases as de­scribed above.

Adjustment of the head rest

Both seat types can be equipped with a head /
neckrest which is adjustable in height and an­gle. Use the long holes and the screw hidden
under the cushion (BodyLink-seat) or the
mounting clamp (ErgoMesh-seat) for setting up
the correct position.

Adjusting the seat position

Caution!The three quick releases have to

be closed firmly (tightening force 15-20 kg /
45 lbs) to safely hold the seat.You must not
open them while riding.After they have been
closed the imprint "close" must be visible. If
the quick releases are not properly tight­ened the seat can move while riding and you
may lose control over your tricycle.

Caution! Do not push or carry your trike
on the head rest,this may damage the head
rest or the seat!

If the clamping screws are tightened too hard,
the handlebar may be deformed,and no prop­er clamping can be achieved.

Please take care that the clamping area of the
stem is thoroughly trimmed and there are no
sharp edges which may cause handlebar failure.

While riding you should allow your arms to
rest in a relaxed position on the handlebars.
Do not push or pull on the handlebars.If the
handlebars turn in the stem clamping during
the ride stop immediately and tighten the
clamping screw of the handlebars.If the han­dlebars are not sufficiently clamped the han­dlebars or the stem may be damaged or de­formed.In this case, safe clamping can no
longer be guaranteed,not even with the cor­rect tightening torque,and handlebars and
stem have to be replaced.

Your bike shop can supply a special fitting lu­bricant that increases friction between handle­bar and stem.

Adjusting the handlebars

Adjusting the handlebar angle

By changing the angle of the handlebars you
can adjust the position of the grip to the
length of your upper body and your arms.

The handlebar consists of two parts. They are
mounted to the stem by a slotted clamp on
each side.The adjustment range in width is 3.5
cm on each side, giving a total range of 7 cm
(aprox.2 ¾").

Most riders are comfortable with a 85° angle
so that the bent grips point upwards and
slightly forward.The more upright the grip po­sition and the narrower the handlebar width,
the larger the minimum possible turning circle
as the handlebars touch your legs or the seat
earlier.

In order to change the angle or the width,
loosen the screws of the stem/handlebar
clamping.Move the handlebars until they are in
your favourite position.Tighten the clamping
screws with

8–10 Nm. Check the correct

clamping of the handlebars by sitting down on
your trike and pulling the handlebars.Doing so
the handlebars must not turn in the stem.

Danger! If the handlebar grips are adjusted
pointing too far forward or too wide,your
hands or the brake levers can touch the
front wheels or mudguards when cornering
sharp,leading to injury.Make sure you have
at least 5 cm (2“) clearance between brake
levers and front wheels / mudguards at all
steering angles.

Caution! If the handlebar grips are adjusted
pointing to far forward,the handlebar can
touch and damage the track rods when cor­nering sharp.Make sure the handlebars con­tact your legs or the seat first before touch­ing the track rods.Damages track rods must
be replaces.

Handlebar width and angle are adjusted with the clamp at the
stem under the main frame.

Caution! Do not exceed the handlebar
width over the „Max“ mark,otherwise a
safe clamping is not possible.

In case your Scorpion fs 26 is equipped with
long handlebars,there is a screw as well as a
quick release at the left handlebar’s clamp.
When folding the bike you need to loosen the
quick release and swivel the left handlebar to
the front.The tightening torque for clamping
screw and quick release’s screw is the same as
mentioned above.

Velotechnik

Adjusting the cable length

You can make smaller adjustments by moving
the cables in their guides at the frame and the
stem,so there is enough clearance for all
movements.If this is not the case you will have
to have your specialist dealer shor ten the ca­bles or replace them by longer ones.

Cover all contact areas where cables move
and touch the frame with sturdy transparent
tape.This protects the paint against scratching
and wear.

Handlebar grips

The grips on the handlebar are susceptible to
wear and tear.Have your grips replaced by
your bike shop once they don't feel comfort­able any more. The grips always need to be at­tached firmly to the handlebar.

16

Adjusting the handlebars

Caution! After having adjusted the handle-

bar position you have to readjust the length
of the brake cables and shifter cables.The
cables have to run smoothly without any
sharp turns and they should not be bent
sharply or stretched when the handlebar is
at maximum angle. Also avoid large bows
that could be caught up by the front wheels
or other parts or touch objects under your
trike.

Caution!When getting on and off the trike,
make sure to avoid pulling at the handle bars
or stepping on the tie rods.To get off the
trike,sit upright on the front seat edge and
then stand up.Grip the front wheels or the
seat back as an extra support, not the han­dlebars.If you pull firmly at the handlebars,
the steering mechanism can be damaged.

Adjusting the suspension

Purpose of suspension adjustment

Your Scorpion fs 26 is suspended on all three
wheels. This system compensates bumps on
the road to make riding more comfor table and
to reduce stress for your tricycle .

A well-adjusted suspension improves the trac­tion of your tricycle on uneven roads.
Especially when riding in a bend this allows a
higher speed and also improves safety.

In order to achieve maximum riding comfort,
the suspension settings have to match your
weight as well as the road condition.

The goals of the adjustment are:

● maximum use of the available suspension

travel without the suspension frequently
bottoming out

● quick reaction of the suspension without

obvious oscillation after having passed
a bump

● avoiding self enf orcing oscillations, that means

increasing oscillations of the suspension
system due to pedaling influence, rhythmic
body movements or permanent wavy
underground

Suspension and damping

The suspension system of the rear swing arm
consists of a spring and a damper.

Often,the terms suspension and damping are
used inaccurate in everyday language.

The spring is the elastic element that com­presses and expands due to the the load
changes,which e.g. occur on bumpy roads.
While expanding,the spring releases the same
energy it took to compress it.

The rear swing arm is suspended with a steel
coil spring in the standard version.The option­al rear shock DT-S

WISS XM180 uses air as

spring medium.
The damper slows down the process of com-

pression and expansion. That means the tricy­cle does not immediately "spring" back to the
initial position or even further than that after
having passed a bump. The damper converts
spring energy into friction and finally into heat,
and thus takes away energy from the suspen­sion system. The damper prevents the spring
from swinging uncontrolled after an initial
stimulation.In addition,the damper helps to
avoid self enforcing oscillations of the suspen­sion caused by recurrent stimulation like ped­aling forces within a crank revolution or the
rhythmic up and down movement of the legs.

In case you have mounted the optional suspen­sion element DT-S

WISS XM180, the hydraulic

damping of the rear suspension is adjustable.

HP

Velotechnik

18

You should always set the damping as low as
possible to give the tricycle the possibility to
quickly react even to several bumps in a row.

You can ride the Scorpion fs 26 with a consid­erably lower damping rate than for example a
MTB:due to the relaxed and steady position of
the body the recumbent does not experience
extreme variations in the load as it is known
from dancing on the pedals while riding uphill
on a mountain bike.

In addition to this,varying pedaling forces have
very little influence on the suspension of the
tricycle due to the No Squat design of the sus­pension system of the Scorpion fs 26.So when
you adjust the damping,always start with a low
damping rate.

It is necessary to choose the correct spring
stiffness to have a well operating suspension
system. The spring stiffness is a measure for
the compression of a spring at a certain load.
It is either given in "N/mm" (Newton per
Millimeters) or "lbs./inch" (Pounds per Inch).
Sometimes you only find "lbs." printed on the
springs.

The spring stiffness of the optional air shock
DT-S

WISS XM180 is set by adjusting the air

pressure.
The suspension is designed in a way that the

spring is compressed partly when you sit
down on your tricycle. This is called negative
suspension travel (or "sag") and it enables the
spring to expand on bumpy roads.(Which is in
fact a definitely positive feature .) You should
choose a spring stiffness with which this nega­tive suspension travel takes up around 30% of
the overall suspension travel.This value usually
provides a very comfortable ride on your sus­pended recumbent trike.

Adjusting to load

The luggage carrier of the Scorpion fs 26 is
mounted to the suspended part of the frame.
That way your luggage is also fully suspended
and it spares the material.Most notably, even
under heavy load the suspension will
compensate an uneven road much better and
quicker compared to a design where the
luggage carrier is mounted to the unsuspended
parts, e .g. the rear swing arm.

Additional luggage changes the load on the
wheels and their suspension. The springs are
further compressed initially through the load
and there is less suspension travel for bumps
while riding.Your suspension will bottom out
more often.

The suspension of the front wheel is less
affected since luggage at the rear rack almost
only puts weight on the rear wheel.Only in
case of heavy luggage on the lowrider under
the seat there is an influence on the front
wheel.

In order to compensate the variations in the
load you can change the pre-load.For details
see the following chapter.

Theoretically adjusting the preload can com­pensate for a load change of approx.10 kg (23
lbs) at the rear wheel.In case of higher vari­ations in the load you will have to exchange
the spring with a spring with different spring
rate. In practice you can often do without it:
the Scorpion fs 26 offers a lot of suspension
travel for a touring trike (80 mm rear /60mm
front).When you choose the spring rate to
have the full 80 mm at your disposal when
your recumbent is under maximum load,you
will have a somewhat smaller but still ver y
comfortable suspension travel when you ride
without luggage.The optional air shock DT­S

WISS XM180 can be easily pumped up to

compensate load increases.

Adjusting the suspension

HP

Velotechnik

Steel spring rear shock

The preload determines how far the suspen­sion compresses when you are sitting on the
tricycle while standing still.

For maximum riding comfort the suspension
should compress by about 30% of the total
suspension travel while you sit on the tricycle
in driving position.

For that purpose measure the distance be­tween the two suspension element bolts or
between rear rack and rear wheel while the
trike is unloaded as well as while sitting on the
tricycle in riding position.Also take into ac­count possible luggage. Find out the total sus­pension travel possible for your tricycle with
the method described above,depending on the
mounted add-on-parts and clips on the piston
rod.The static compression should amount to
about one third of the overall suspension trav­el.

You can affect this negative suspension travel
depending on how much you weigh and how
much you load your trike either by adjusting
the suspension pre-load for fine tuning or by
replacing the spring with a spring with a differ­ent stiffness in the rough tuning.

In order to adjust the suspension pre-load
turn the adjustment ring on the threaded part
of the suspension element by hand. Turning the
adjustment ring clockwise (looking at it from
behind) reduces the preload,turning it coun­terclockwise you screw the adjustment ring
towards the spring and increase the suspen­sion pre-load.It is helpful to turn the spring
together with the adjustment ring.

Adjusting your new trike

19

Adjusting the rear suspension ele­ment

For the rear suspension of the Scorpion fs 26
a spring element is combined with a hydraulic
damping unit in a suspension element. The
damping results from fluid friction of an oil
flowing through thin holes of a valve in be­tween two chambers inside the damper.A
slightly noticeable sound that may occur from
this oil flow is normal.Due to the fluid friction
the spring element may heat up, therefore
touch the spring element after a ride only very
carefully.

The Scorpion fs 26 comes standard with a
steel spring rear shock.As an option you can
get the air shock DT-S

WISS XM180 that uses

air as spring medium.

Danger! While adjusting the rear suspen­sion element never load the tricycle e.g.by
resting on the seat or loading the rear rack
when your hands or tools are close to the
suspension element.Your hands may get
caught and squeezed when the suspension
compresses.

Danger!The suspension elements are filled
with gas under high pressure.Never try to
open the damper or to remove the screw at
the gas tank.Inside the damper there are no
user serviceable parts. In case of damage
you will have to take the complete suspen­sion element to your dealer.

HP

Velotechnik

20

Adjusting the suspension

The adjustment ring should be turned not
more than five turns (measured from the re­laxed position) towards the spring.If the sus­pension compresses still too far even after six
turns,the spring is too soft and has to be re­placed by a harder spring. A too high preload
with a too soft spring will not take advantage
of the full comfort potential.

You can find more information on changing
springs in this manual under "Maintenance and
Care",page 46.

Steel spring suspension element with fixed damping rate.

The suspension travel is adjusted by adding clips to the piston
rod of the spring element.

Danger!Take care that the rear wheel or
mudguard or suspension element never hit
the frame, seat, rear rack or luggage box
while the suspension is fully compressed.

Therefore relax the spring completely by
turning the spring retention disc on the
thread of the spring element as far as possi­ble (before this,push the possibly existing
safety spring ring from its slot in the thread­ed section as far as possible).Have a second
person sit down on the tricycle and make
the suspension bottom out by leaning on
the seat or the rear rack.

If the distance between the wheel or mud­guard and the frame,seat, or rear rack is
smaller than 1 cm you will have to mount an
additional spacer. In case you don't, the mud­guard may break suddenly or the rear wheel
might be blocked which can lead to serious
crashes.

Danger!The adjustment ring has always to
be screwed on so far that the spring has no
play when unloaded.Otherwise the adjust­ment ring could come loose through shocks
while riding and the slotted rear spring re­tention disc comes off.In that case the sus­pension element may be damaged or the
rear wheel can hit the frame or rear rack,
which may lead to serious falls.
Always have an initial preload of at least half
a turn on the spring.

Air shock DT.S

WISS XM180

Please follow the instructions in the separate
manual provided by the rear shock manufac­turer.

This rear shock contains pressurized air in a
main („positive“) air chamber as suspension
medium.Air shocks are lighter than steel
spring rear shocks.Another advantage is that
the spring stiffness can be easily adjusted with
an air pump:By increasing the pressure the
spring becomes harder.

Air shocks have a progressive spring behaviour,
whereas steel springs have a linear spring be­haviour.This means that the air shock gets
progressively harder,e.g. it is much stiffer when
fully compressed than when only slightly com­pressed.

The advantage of this progressive spring be­haviour is the good bottom-out protection
when heavily loaded.

The valve for the air chamber is located at the
back end of the air shock. The valve is protect­ed by a metal valve cap.

To pump up the air shock you need a special
air pump designed for bicycle air shocks.It
must feature a fitting schrader valve adaptor
and a pressure indicator.

When attaching or removing the pump
to/from the valve,you will lose some air pres­sure (about 0,5-1 bar). Take off the pump
quickly.

Recommended pressure settings

load pressure

up to 80 kg (183 lbs) 7.5 bar
up to 110 kg (242 lbs) 9.0 bar
up to 140 kg (308 lbs) 10.5 bar
Maximum allowed pressure is 18 bar.

Danger!Take care that the rear wheel or
mudguard or suspension element never hit
the frame, seat or rear rack box while the
suspension is fully compressed.

Therefore fully deflate the air shock.Have a
second person sit down on the tricycle and
make the suspension bottom out by pushing
on the seat or the rear rack.

If the distance between the wheel or mud­guard and the frame,seat or rear rack is
smaller than 1 cm you will have to have your
trike dealer mount an additional spacer in­side the air shock.In case you don't,the
mudguard may break suddenly or the rear
wheel might be blocked which can lead to
serious crashes.

Adjusting the suspension

Adjusting the damping

By adjusting the damping you can adjust the
performance of the suspension precisely to
your individual riding situation.A rough street
with many harsh bumps that occur in a row or
even cobblestones needs a low damping rate
while a road with long stretched bumps that
occur more regularly needs a stronger damp­ing to achieve a smooth road holding.

When you add a lot of luggage you will need
to adjust the spring stiffness;in that case an
adjustment of the damping may even give you
more riding comfort.

Finally, the oil used in the damper becomes
thicker and more viscous at lower tempera­tures,which can be compensated through a
change in the damper setting.

Please note that you can seriously spoil the
riding comfort by a bad damper setting,espe­cially caused by unsystematic playing with the
knobs that may result in much to high damping
values.In the worst case the suspension ele­ment will neither compress nor decompress.If
you are in doubt please consult your local
dealer.

The rebound damping prevents an eventual
"jumping" of the rear wheel and provides a
good traction.By improving the road surface
contact the suspension of the Scorpion fs 26
also increases your riding safety.

A higher damping value prolongs the time until
the decompression movement is finished.Only
then can the suspension compensate the next
shock with the full suspension travel.
Therefore,when you ride on very bumpy
streets with shocks that occur fast in a row
you might want to use a lower damping value.

A good setting for maximum comfort is
achieved when the rear wheel decompresses
completely after a shock and then oscillates
only once. In order to check the adjustment
you will need a second person that compress­es the suspension by pushing the tricycle down
while you are sitting on the tricycle in the rid­ing position. The other person can then ob­serve the suspension movements.

In order to adjust the damping during decom­pression,turn the adjustment knob on top of
the rear end of the suspension element.

If you turn the knob in direction of the „-“ you
will get less damping and thus faster decom­pression. Turning the knob in direction of the
„+“ will give you more damping and thus slow­er decompression.

Air Shock DT-Swiss XM180 Damping ist adjusted with the red
knob at the rear end.The shock must be installed with the loc k­out lever on the backside facing down to avoid a collision
between lever and frame when the suspension is moving.

Adjusting the front suspension

In addition to the suspended rear swing arm,
the Scorpion fs 26 is equipped with a suspend­ed front axle.It is designed as a so called
McPherson strut.That means, the left (or right)
suspension strut's upper end is supported in
the frame while it is linked to a single wish­bone on its bottom end. The front wheel is di­rectly attached to the suspension strut,which
is the knuckle at the same time.

Inside the suspension strut a steel spring is
combined with MCU-elastomers. The front
suspension is damped by friction between
stanchion tube and a circular elastomer band
situated between the bushings as well as by
friction inside the elastomers.

To decrease body roll in during fast cornering
and to provide high comfort at the same time,
the front axle is equipped with a stabilizer bar.
This bar is linked elastically with both wish­bones and the main frame.As the stabilizer bar
works as a torsional spring,it supports the
outside wheel's suspension while cornering.

For maximum comfort,30% of the suspension
travel should be used when you sit on your
trike in a normal driving position (the same is
valid for the rear suspension).For the
Scorpion fs 26 front suspension,this means 20
mm of travel (so called "sag").

Your Scorpion has reached a sag of 20 mm
when the upper edge of the knuckle which
you can feel underneath the shock boot coin­cides with the lower edge of the headtubes of
the main frame. You can fine tune this sag ac­cording to your weight and your additional
luggage by adjusting the preload of the springs.
To change the spring rate in a wider range , you
can replace the steel spring or interchange
elastomers and spacers inside the suspension
struts.For further instructions, please see the
chapter "Maintenance and Care" on page 48.

To adjust the preload of the front suspension,
unscrew the strut end cap using a hex key size

5.Now the preload adjuster is visible, which
can be turned by a hex key size 5,too.

Turn the preload adjuster counter clockwise
to decrease preload,turn it clockwise to in­crease preload.The maximum depth is limited,
so stop turning when resistance rises suddenly.
After adjusting,place the cap on the strut and
tighten it gently (1-2Nm).

The damping rate can be altered by exchanging
the elastomer bands inside the suspension
struts,see “Removing and disassembling the
suspension struts” on page 51.

Danger!While adjusting the front suspen­sion,never load the tricycle, e.g. by resting
on the seat or loading the racks when your
hands or tools are close to the suspension
struts.Your hands may be bruised when the
suspension compresses.

Danger!The mounted spring is under ten­sion.Do not remove the preload adjuster
when adjusting the spring preload.Make
sure the adjusting disc's thread is fully
screwed into the stanchion tube.Otherwise
it may become loose and hurt you.

Learning the new riding technique

Your new tricycle has been assembled by your
dealer and adjusted together with you as de­scribed on the previous pages under
"Adjusting your new tricycle".Before you sit
down on your trike and enjoy your first ride
please make yourself familiar with the instruc­tions on riding technique and handling.

To ride this recumbent you will have to make
yourself acquainted with the different riding
position.Make sure that you and all other fu­ture users of this tricycle will have read this
manual carefully prior to the first ride.If you
are in doubt please consult your local dealer.

Before the first ride the users of this recum­bent have to practice and make themselves fa­miliar with the different handling.We recom­mend to practice on a quiet road away from
traffic. Before you ride the tricycle in traffic
you must master the handling completely.

Learning the new riding technique

Keep all three wheels on the ground while rid­ing.If you are cornering too fast,your trike
can be upset and fall over.Lean into curves
when turning sharply.At high speed, keep your
upper body quiet as any upper body move­ments can influence the steering of the trike.

Practice cornering away from traffic to learn
what speed is safe at a specific turning angle.

If you lift up a front wheel,immediately steer
in the opposite direction to bring it safely back
to the ground.

Caution!When getting on and off the trike,
make sure to avoid pulling at the handle bars
or stepping on the tie rods.To get off the
trike,sit upright on the front seat edge and
then stand up.Grip the front wheels or the
seat back as extra support, not the handle­bars.If you pull firmly at the handlebars,the
steering can be damaged.

Danger! Never touch the ground with your
feet while the tricycle is still moving. The
feet could be caught on the ground and be
pulled backwards and dragged under the
cross bar which could lead to a serious in­jury.We strongly recommend to use a pedal
binding system like clipless pedals or toe
clips and straps.

Danger! Please be aware that due to your
low seat height other road users may notice
you very late. Ride anticipator y with this in
mind. This is especially impor tant while rid­ing in darkness.You yourself have a much
better view than others perceive you.Ride
defensively.We recommend to mount a well
visible and reflecting flag to the tricycle
while using it in traffic. Please ask your deal­er for more information.

Wear protective clothing

Riding a tricycle is a potentially dangerous
sport where accidents can happen even when
you take care of every safety instruction pre­scribed.

We recommend you to wear an approved bi­cycle helmet that fits well.Protect yourself by
wearing special sports clothing that fits tight
and is reflective.If you're wearing wide pants
use clips to protect them from getting caught
in the chain - or use an old fashioned method
and put the pants in your sockets.

When you fall with a recumbent you’ll usually
land on the side of your hips and your hands.
Wearing reinforced cycling shorts and gloves
reduces the danger of skin injuries consider­ably.

Use clipless pedals

The pedals of your Scorpion fs 26 can be up­graded on demand with a binding system.As
soon as you are comfortable with riding your
Scorpion you should use those clipless pedals.
Due to the rigid connection between shoe and
pedal you don't have to keep your foot on the
pedals with pressure anymore. This enables a
more relaxed and round pedaling movement
where you may even pull a little on the pedals.
Without this connection to the pedals your
feet may come off suddenly which may result
in a fall.Modern system pedals with binding
therefore contribute to safe riding.

At first you will have to practice with these
pedals to make sure that you can get off quick­ly in a dangerous situation.Please read the
manual of the pedal manufacturer that comes
with this manual and have your dealer explain
the use of the pedals to you.In the beginning
set the release force of the binding to a low
value to make sure you can get off safely.

Please use exclusively the original shoe plates /
cleats from the manufacturer of the pedals,do
not use any other brand.If you're using shoe
plates that are not authorised the binding sys­tem won't work properly.

Slowly increase the strain

We recommend you to perform only short
rides without much power during the first
weeks.

Always use a low gear and ride with a high
pedaling frequency. Only after having acquired
some training do increase the strain slowly.

When you ride on a recumbent you use differ­ent muscles than on a conventional bicycle,
and they have to be trained first.The very high
position of the bottom bracket requires your
muscles and blood transport system to slowly
familiarise with the new position.

In case of an overload the blood circulation in
your legs may be affected which shows in loss
of power,a prickling in the toes, falling asleep
of the legs or cramps. When you feature a
sporty way of riding it can take up to 6
months until you have become accustomed to
your new recumbent.

If there is pain in your knees occuring while
riding this is usually the result of too much
power put into pedaling.The good suppor t of
the back sometimes misleads to putting the
full power of the legs in the pedal,similar to
the leg training machines in a fitness center.
When you repeat it regularly it is harmful for
the knees.Pain in the knees often results from
an overuse of the muscles in the knee that can
also be strengthened by exercise.

Also,a wrong adjustment of the front boom to
the leg length (in most cases too short) can
lead to pain in the knees.

Your pedaling cadence should stay between
80-100 revolutions per minute and not fall be­low 60 revolutions when going uphill.If neces­sary have your specialist dealer adjust the gear
range to your riding style and the terrain you
usually ride.

You will find many tips on proper training for
cyclists in miscellaneous books and magazines
for cyclists.

In case of persistent problems please consult
your doctor.

Do not ride freehand

How to ride correctly and safely

Always adjust your speed to the traffic , the
road and the weather conditions.Ride slowly
in curves and on unknown roads. Always ride
at a safe distance from other road users,and
when you ride in a group never ride side by
side.

When you approach a traffic light never ride
past the line of waiting cars since even the
most attentive car driver may not see you due
to your low riding position.

When riding the S-Pedelec,be aware of the
higher speed level this vehicle provides. It may
be unfamiliar for other people in traffic.Ride
defensively.Only ride at higher speeds where
and when this is safe!

Strain, Riding freehand,Way of riding

Danger! In order to ride safely you have to

keep both hands at the handlebar.Even
when signaling keep at least one hand at the
handlebar. Otherwise , unforeseen bumps in
the road or oscillations of the steering may
lead to a serious fall.

Quick release levers

Quick release levers hold wheels and seat in
position.

A quick release lever consists of two basic
parts: the lever on one side provides the
clamping force. With the adjusting nut on the
other side you adjust the clamping tension on
the screw thread.

To open the quick release, move the lever
away from the frame. In doing so the inscrip­tion "open" should be visible on the lever.

To close the quick release, move the lever with
power in the other direction so that the word
"close" is visible on the outward side of the
lever.At the start of the lever's motion,for,say,
half of its movement,the lever should move
very easily, without any clamping action.

In the second half of the lever's movement the
force on the leer should increase considerably,
corresponding in the end to 15-20 kg (46 lbs).

In its final position the lever should lie parallel
with the tricycle and should not stick out to
one side.

Check the security of the lever by attempting
to twist the lever. If the lever can be made to
pivot around in a circle the clamping is too
loose. You must re-open the quick release,
hold the lever and increase the clamping ten­sion.Do this by screwing the adjustment nut
on the other side by half a turn.Close the
lever and check the clamping anew.

Finally, check that the part being secured is
firmly fixed:Lift each wheel several inches off
the ground and give it a slap onto the tire
from above. A properly fixed wheel will remain
secure in the frame's dropouts.

Parts that are fastened with a quick release
open easily.Thus, they are more susceptible to
theft. Therefore, always secure the wheels with
a lock when you park your tricycle.It is also
possible to exchange the quick releases with
special security screws (e.g.from P

ITLOCK or

KRYPTONITE) that can only be opened with a
special tool.For this please consult your local
specialist dealer.

Way of Riding, Quick release levers

Caution! Always carry your tricycle over

stairs and curb stones.Do not ride through
big road holes.Especially when road holes
are filled with water it is very difficult to
guess how deep they really are . In case you
hit such an obstacle frame and steering may
be damaged which can result in a serious
fall.At first,the damage may be unnoticed.
Please check your tricycle immediately for
deformations and cracks.If you are in doubt
please consult your local dealer.

Danger! An incompletely or improperly
closed quick release can result in parts com­ing loose, and hence in a crash, possibly re­sulting in serious injury.

Brakes

The Scorpion fs 26 is equipped with a power­ful high-quality braking system.Please read the
separate manual of the brake manufacturer
that comes with your trike for details.

Make yourself familiar with the braking system.
In the standard assembly, both front wheel
brakes are operated separately: The left brake
lever operates the left front brake,the right
brake lever operates the right front brake.

If your trike is equipped with a rear brake or a
parking brake,use this brake only as an emer­gency brake in the unlikely event of a failure of
the front brakes.If the rear wheel is locked up,
the trike can immediately spin around and
slide to the side. Remember which lever pulls
the front brake and which the rear brake.

Do not brake in a bend,always brake before a
bend.Braking increases the risk of slipping.
Especially when it is wet the rear wheel imme­diately slides out of the bend while braking
and this can result in a serious fall!

As an option,you trike can be equipped with a
coupled braking system with one brake lever
operating both front brakes.

For optimum handling soem braking systems
provide the option to adjust the distance be­tween the brake grip and the handlebar with a
small hex-headed screw at the grip,please see
the respective manual for details.

The braking effect of modern braking systems
can be more powerful than what you have
been used to until now. Brake carefully.When
you brake too hard with the front brake the
rear wheel may lift off the street and the trike
may tumble over.

If you should hear any unusual sounds while
braking the brake pads might be worn out.Do
not use your trike any fur ther until you have
checked the brake pads according to the man­ual of the brake manufacturer or asked your
local dealer to do so.

Brakes

Danger! Make sure to brake evenly using

both hands.Braking unevenly or only one
side could influence the steering of your
trike.Maximum braking performance is only
achieved when braking with both hands.

Danger! In case you get into a situation like
that during an emergency stop you have to
let go of the brakes immediately,balance
your trike and brake again. If you are not fa­miliar with the brakes we recommend you
to train at first at low speed and with little
braking effect until you find the correct dose
for an emergency stop.

Danger! Please note that the braking dis­tance is much longer when it is wet or when
the trike is heavily loaded. When riding on
wet,sandy, icy or slippery roads you have to
use the front brake ver y carefully to avoid
that your front wheels slip. If they do so you
will no longer be able to control your trike ,
which might lead to a serious crash.

New braking systems,new brake pads and new
brake discs need a break-in period to achieve
maximum brake power.This period lasts for
about 30-40 stops from about 30 km/h
(20mph),which should be done in a safe area
without traffic.

Check before every ride:

● that the braking system does not have any da

mages or leaks by activating the lever,holding
it and checking the hose connections for
possible leaks.

● that the brake lever pressure is ok by pulling

the lever and ensuring that full braking per
formance is achieved before the lever tou
ches the handlebar. If this is not the case , ad
just the cable or change the brake pads,for
hydraulic disc brakes pull the lever several ti
mes (pump) until it feels firm.

● check the hydraulic braking system for the

correct pressure by pulling the lever, holding
the pressure and checking the hose connec
tions, bleeding screw and compensating tank
for possible leaks.

Parking brake

Always secure your trike against rolling away
when parked.

In the standard assembly, the brake levers are
equipped with a parking brake-button that locks
the pulled lever. To release the parking brake,
pull the brake lever.

As an option the trike can be equipped with a
parking brake that is operated with a thumb­shifter mounted at the handlebar. It is connect­ed with a V-brake at the rear wheel.Make sure
to fully open the parking brake before you start
riding.

Danger!Always make sure that the disc and
brake pads are free of oil and grease. If these
parts are dirty please do not use your tricy­cle. You can clean oily discs with alcohol or a
special spray.Oily brake pads have to be re­placed.If you are in doubt,please have your
specialist dealer maintain your braking sys­tem.

Danger! Disc brakes can overheat on long
down hill rides,fade and fail! On down hill
rides,do not brake constantly, but in several
intervals with higher pressure. If you notice
that the brake power starts to fade, stop im­mediately and let your brakes cool down.

Danger! Never touch neither the brake
disc nor the brake caliper after long braking
as this may cause serious injury (risk of
burns).

Gear system

30

Gear system

With the gear system you can adjust the ped­aling frequency, i.e . the number of revolutions
of the crank per minute, to the terrain and the
desired speed.

Your pedaling frequency should stay between
80-100 revolutions per minute and not fall be­low 60 while going uphill.If necessary consult
your local dealer and have him adapt the gear
range to your style of riding.

Your Scorpion fs 26 comes standard with a de­railleur gear or with a internal hub gear sys­tem. The following section refers to the de­railleur gear system only. Please also refer to
the manual of the gear manufacturer.

You operate the gear changer with the grip­shifters or bar end shifters on the handlebars.

The right lever for the rear derailleur has an
index derailleur system that positions the
chain always on the chosen sprocket, so that
you don't have to "search" for the gears.

The left barend shifter is not indexed so you
have to adjust the front derailleur while shift­ing by slightly moving the shifter to stop the
front derailleur from dragging against the chain
while pedaling.

Riding a recumbent requires foresighted gear
shifting.Before stopping you should timely
change in a low gear to make it easy to start
off again,without having to pedal heavily.

You should only change the gears while you
keep pedaling,smoothly and without applying
great force,all the time that the chain is mov­ing between the sprockets.

29

Due to the long cables that expand under
pressure and the housing that compresses un­der pressure it may be helpful for changing
gears quickly to turn the bar end shifter a little
bit farther than necessary to select a gear and
turn it back to the indexed position once the
chain has properly shifted ("overshift").

When the chain length has been properly ad­justed you can choose every combination of
front chain rings and rear sprockets to shift
gears.However, it is useful to ride the lowest
gears (the biggest rear sprocket) with the
smallest chain ring,the middle gears with the
middle chain ring and the highest (fastest)
gears with the biggest chain ring.

The setup of the chain rings and sprockets
leads to an overlap of some gears.This means
that different combinations of chain rings and
sprockets can result in the same gear ratio. It
would be possible to arrange a gear system so
that double gears do not occur but this re­quires a lot of concentration when you shift
gears while riding,since you will always have to
change the rear sprockets as well as the front
chain rings.If you would like to change the set­up of your gears please consult your local
dealer.

Caution! Under no circumstances allow the
trike to roll back while changing the rear
gears,or try to pull the trike backwards
when the gear shifter lever has been moved,
as this will damage the rear derailleur.

Danger! Practice shifting gears on a traffic­free street.In the course of this make your­self familiar with the functioning of the bar
end shifters.Doing this in traffic could dis­tract your attention from possible dangers.

Lighting system

If you want to ride your trike on public
streets,it must be equipped with a legal light
system.Do not only use your lights in the dark
but also in the twilight of dusk and dawn.Due
to laws and regulations the brightness of bicy­cle lights may be considerably lower than that
of other vehicles. Therefore always keep in
mind that other road-users may only see you
very late or not at all.

For the Scorpion fs 26,HP V

ELOTECHNIK offers

a dynamo light systems with a tire dynamo or
a hub dynamo.The S-Pedelec lighting system is
powered by the propulsion system’s accumula­tor.

Both light systems come with strong LEDs for
headlamp and rear light. The LEDs last consi­derably longer (approx.100.000 working
hours) than a light bulb.For your safety the
light system has a parking light system both at
the front and at the rear light,which makes
the LEDs shine on approximately 10 minutes
after you have stopped riding.The electronic
system is maintenance free.Because of the ca­pacitors used you don't have to worry about
batteries.

The cables and the contacts can be affected by
corrosion or mechanical damage. Therefore,
check the light system before every ride.

Tir

e

dynamo

You turn on the light system with the tire dy­namo at the rear wheel by unlocking the swiv­elling dynamo.For this purpose you press the
red button at the dynamo until it moves to­wards the rear wheel.To turn the light off,
swivel the dynamo back to its initial position
by hand.

You can adjust the pressure of the dynamo
against the wheel with the turning knob at the
side.The pressure is right when the dynamo
wheel just does not slip at the wheel,if the
light flickers,the pressure is too low and you
have to increase it.The dynamo should be po­sitioned in a way that the extension of the dy­namo axle points through the center of the
wheel. Take care that the dynamo is mounted
safely and can’t be turned. Worn dynamo
wheels can be exchanged.Please ask your spe­cialist dealer.

Lighting system

You switch on the tire dynamo by pressing the red button.To
switch off the dynamo move it away from the wheel.

Danger! Do not try to move the dynamo
while riding,your hands can be caught in the
wheel and be injured! To turn the light sys­tem on or off stop riding,get up from your
trike and only then move the dynamo.

Danger!The dynamo must always be safely
fastened to the bracket at the frame,so that
it can not turn.If the screws come loose the
dynamo can get caught in the spokes and
block the rear wheel - danger of a serious
fall! Always check the position and secure at­tachment of the dynamo before a ride.

Lighting system

Hub dynamo

The lighting system with a hub dynamo is
switched on electrically. For this purpose you
will find a switch on the back of the rear light
with three labelled switch positions.With the
switch you can turn the lighting system ON,
OFF or set it to SENSOR.In the SENSOR po­sition a twilight sensor in the lamp turns the
lighting system on and off automatically de­pending on the brightness of the environment.

The SON hub dynamo is highly efficient and
works silently.When the dynamo is turned off
it has a very low turning resistance.Although
you can feel the single poles of the used per­manent magnets very distinctly when turning it
by hand the real rolling resistance is minute .
(The loss is below 1 W at 15 km/h / 9,5 mph.)

You switch on the hub generator light system with the integrated
switch at the front light.

S–Pedelec

The Scorpion fs 26 S-Pedelec lighting system is
supplied with 12 V DCout of the propulsion
system’s accumulator.

To turn the system on and off there is a switch
at the back of the headlight with two postions
ON and OFF.Additionally,there is a legally re­quired position light mounted under the head­light.It is switched on and off together with
the headlight.

The rear light features an integrated brake
light which is required for this type of vehicle .
The brake light is supported with energy at all
times the accumulator is mounted to the bike.
The brake light is switched on and off by the
brake switch in the brake levers.

Caution! Only ride your S-Pedelec with ac­cumulator installed. Without accumulator
lighting system and brake light are out of
function. The lighting equipment according to
S-Pedelec regulation is not sufficient to use
the S-Pedelec as a bike according to StVZO
rules even during daytime .

Use the switch at the head light to set the S-Pedelec lighting sy­stem into operation.

Folding

Grab the quick release lever laying on the left
side of the frame and turn it forward up
around its axis.

Swivel the lever past the lower seat quick
release until it touches the front frame part.

Use your right hand to pull the whole hinge
upwards a little bit.At the same time pull away
the securing tab from the hinge with your fin­gertips to open the folding hinge. If necessar y
push a little bit from the side where the quick
release lever is situated.

Grab the main tube behind the front boom
clamps with your right hand and the seat stay
of the swingarm with your left hand.Swivel the
rear part onto the front part until the rubber
buffer at the upper seat connection quick re­lease touches the cross tube of the frame
front part.
While folding take care that the handlebars are
in a position where they will not crash into
the frame rear part.In case your Scorpion fs
26 is equipped with long handlebars,please use
the quick release at the stem clamp to fold the
left handlebar side to the front (see page 16).
Make sure all cables and electric wires are
long enough to allow proper folding.The chain
tubes are connected by a flexible rubber joint
positioned in the area of the folding hinge.

Taking off the seat

Open all three quick release levers of the seat
mountings:Unscrew the nut of the upper seat
quick release approximately 4 turns.Turn the
quick release levers of the middle and lower
seat quick release counter clockwise approxi­mately 4 turns.
With a lowrider rack or water bottle moun­ting installed,space is limited and it may be ea­sier to hold the quick release lever and turn
the flat nut on the right side (chainside) of the
seat mountings with a 5 mm Allen key.

Pull the lower seat half out of its mountings,
then the upper seat half.

Folding the frame

Your Scorpion fs 26 folding hinge features a
snap-in function.It makes folding easier and
prevents the frame from folding even when the
quick release is not fastened.

To fold the frame stand behind the main fra­me’s crosstube and look to the left front
wheel.

Caution!When storing the seat,please take
care not to bend or break the seat mount­ings.Protect the edges of the seat mountings
with padding to avoid scratching other ob­jects with the seat mountings.

34

HP

Velotechnik

When folded the frame must be protected
against unwanted unfolding. To do so the vel­cro strap attached to the seat tube must be
stripped away and attached to the cross tube
where its counterpart is positioned.

Taking off the front wheels

To achieve an even smaller package,you can
take off the front wheels (see page 58).It is al-
so possible to remove the mudguards in addi­tion (see page 56).

Unfolding

To unfold and reassemble your trike,please
follow the steps above in the opposite order.
Make sure that after unfolding the quick
release lever rests on the front frame part.
Else the snap-in mechanism will not work pro­perly.
Lift the folding hinge until the securing tab
snaps in noticeably. Some momentum will be
helpful.Now close the quick release lever until
it touches the rear frame part.

Mounting the seat

As first step merge the lower seat connection
sheets with their respective connection tube
on the frame.Align the seat to the frame cen­ter.Then slide the middle and upper seat con­nection sheets with their openings on the re­spective quick release.Be careful to not cause
any paint damage. With the BodyLink-seat it is
possible to first push in the middle seat con­nection and then the upper because of its fle­xibility. In case the seat can not be mounted
easily check the quick releases are loosened
enough (if necessary unscrew the nuts a little
bit more).It may be helpful to punch the seat
with your hand to properly fit the seat to the
bike.
Close the quick releases.Please refer to the
hints given on page 27.

Danger! Before riding your trike, make sure
the quick release is securely closed.The se­curing tab must be locked and the quick re­lease lever must be lay on the rear frame
part. Cables or wires must run free.The
handlebar must turn easily and freely.All seat
quick releases must be closed properly.

Maintenance and care

Your Scorpion fs 26 is equipped with the latest
bicycle technology that does not require much
maintenance.

However, you will have to maintain your bicy­cle regularly, as it is with other vehicles too.At
least once a year the bicycle has to be taken
to a bicycle mechanic for an overall service.
Only this way a long lasting and safe function
of all parts of your bicycle can be guaranteed.
It maintains the value of your bicycle as well as
the fun and the safety while riding for many
years.

Read in this chapter how to perform smaller
maintenance and care works between the
services.

For a quick overview of the works to be done
take a look at the Warranty Pass on page 66.

Wear and Tear

As on many other vehicles,some parts on a
bicycle are affected by wear and tear.The life­time expectation of these parts depends on
the intensity and type of use as well as on the
maintenance and care.Please keep in mind that
the process of wear and tear is normal and no
reason for a warranty claim against your deal­er or HP V

ELOTECHNIK.

You will find more specific information on
wear and tear in the chapters on the relevant
parts.

Caution!The maintenance works on this
recumbent partly require special tools and
skills.Do only work within your limits and,
in the interests of your own safety, do not
go beyond.Should you be uncertain at any
point,get in contact with your local dealer.

Brakes

The brake pads suffer from wear due to fric­tion and have to be exchanged then.
Depending on riding conditions,they can last
bewteen a few hundred up to several thousand
kilometers.Please read the manual of the
brake manufacturer carefully.

Cable oper

ated (mechanical) brakes

The brake pads of your brakes are worn when
you can pull the lever further and further to
the handlebar before the pads touch the rim.

To compensate the wear of the brake pads
you can tighten the cable with the adjuster
barrel where the cable touches the brake
lever. First loosen the locknut,then unscrew
the barrel so far that the wheel still turns,
barely not touching the pads,hold the barrel
and tighten the locknut again towards the
brake lever housing. Take care that the barrel’s
slot points downwards to prevent moisture
from entering.

Caution! Keep the brake cable clean where
it is not protected by the cable housing.Due
to the mounting position of the brake lever,
moisture and dirt may enter the cable and
cause drag and excessive wear. Lubricate the
ends of the cable to protect against mois­ture.

Caution! Damaged cables with single wires
sticking out have to be replaced immediately.
Otherwise your braking system may fail ­danger! Please take care that the cable ends
are always protected with a cap.
Always keep the cables shor tly trimmed.
Leaving too much cable extending past the
cable anchor can result in the cable catching
in the rotor or wheel causing the wheel to
lock up.

Mechanical disc brakes

To readjust the brake pads you have to use the
big red knobs on each side of the brake
caliper.Adjust the inner and the outer pad
evenly.In case you are not sure,have this ad­justment work done by a qualified bike me­chanic.

Check your brake pads frequently as explained
in the manual supplied by the brake manufac­turer.Worn brake pads,oily or damaged pads
must be replaced immediately by a qualified
bike mechanic.

Hydr

aulic brakes

Hydraulic brakes on HP V

ELOTECHNIK bikes use

low viscosity mineral oil that,contrary to
DOT brake fluid used in cars,does not absorb
water.Thus, you don't have to change the oil.
Please read the brake manufacturer’s manual
that comes with the trike.In case of a dam­aged hose or any leakage of oil always consult
a qualified technician in a bike shop.

Hydr

aulic disc brakes

Hydraulic disc brakes on the Scorpion fs 26
feature a fully automatic pad wear adjustment.
Brake pads and discs are subject to wear,
therefore regularly check the thickness of your
brake pads and discs and replace them if nec­essary. The minimum thickness of the brake
pad is
1 mm,of the brake disc it is 1,7 mm.For fur­ther and more detailed information on your
disc brake model please refer to the brake
manufacturer’s manual.

Brakes

Danger!All maintenance work on the hy-

draulic system of your brakes may only be
carried out by a qualified technician.In case
these works are carried out without the re­quired knowledge and skills the braking sys­tem might fail which can lead to a serious
crash.

Caution! Never activate the brake lever
with the brake pads not in place or with the
wheel dismounted. When you transport the
bicycle without wheels always use the trans­port clips delivered with your trike or put a
piece of cardboard in the brake caliper to
replace the disc.Carefully separate brake
pads that have moved together with a
screwdriver.

Caution! Keep the brake lever clean.Due
to the mounting position,water and dirt can
collect inside the lever around the hydraulic
cylinder.This may lead to excessive wear or
leakage of the hydraulic system.

Danger! If the brake pads or the brake disc
are worn out (pads:thickness less than 2,5
mm including metal back,disc: thickness less
than 1,7 mm) the pads may be torn out of
the caliper while braking. This leads to total
loss of brake power.

Danger!The hose at the left knuckle must
not be routed under the track rod.This may
lead to snapping off the hose.The hose
should leave the caliper slope upwards and
run in a wide bow to the track rod.The zip
ties fixing the hose to the track rod must be
tightened properly to prevent it from mo­ving.

The bow of the hose is routed under the track rod:Danger of
snapping off the hose (cf.arrow).

All moving parts of the gear system are affect­ed by wear.Cleaning and lubricating these
parts frequently can prolong the life of these
parts. However,they will have to be replaced
once worn out.

The cables have to be checked, cleaned and
serviced regularly. Expect more wear and cor­rosion when the trike is often parked outside
in bad weather conditions.

34

Gear System

Please read the manual of the gear system ma­nufacturer carefully before working on the
gear system.

Your dealer will adjust your derailleur gearing
system carefully before handing over the trike.
But during the first 300 kilometres (186 miles)
of riding the cables can stretch,making the
gear indexing imprecise. The chain then climbs
only hesitantly onto the next sprocket.

Adjusting the gear inde

xing for the rear

derailleur

Adjust the adjuster barrel where the shift ca­ble touches the rear derailleur.Do it in small
steps of half a turn.

Check after each adjustment whether the
chain moves smoothly up to the next larger
sprocket.To do this,either turn the cranks by
hand or ride the trike.

When the chain climbs up easily, you need to
check that it still goes down easily onto the
smallest sprocket.If necessar y turn the ad­juster barrel a little more and then try shifting
gears again.

Gear system

Danger! If the chain shifts over the smallest

or the biggest sprocket you have to readjust
the end-limit adjusters of the rear or the
front derailleur.Incorrect adjustment can
lead to the chain coming off,getting stuck or
damaging the spokes,which may result in se­rious falls. The adjustment of the end-limit
adjusters is a job for the professional bike
mechanic.

Danger! If the trike falls over, the derailleur
or its mounting can be bent which results in
a change of the derailleur movement range.
Check the movement range and have it
readjusted by your bicycle mechanic,if nec­essary.

Caution! Damaged cables that show for ex­ample single wires have to be changed im­mediately. Otherwise they may damage your
gear system. Take care that the ends of the
cables are protected with fitting caps.

Do not use any solvents to clean the chain!
The solvent washes the oil off the bearing
parts, stays there and dilutes the fresh oil so
that a sufficient lubrication is not guaranteed.If
you have treated the chain with a solvent you
will have to heat it up with a hot air gun or
boil it in chain grease.

An effective protection against corrosion is
crucial for a long chain life.Some minutes after
you have oiled the chain rub it with a cloth to
remove superfluous oil from the outer surface .
Wax the chain thoroughly with a wax spray.
The wax keeps off water,protects from corro­sion and makes dirt fall off easily.

If the chain has become wet after riding in the
rain you should put your bicycle in a dry and
heated room,and every day you should turn
the crank and so move the chain until it is dry
again.Otherwise it is difficult for the moisture
in the tubes to evaporate which may lead to
corrosion at the chain.

35

Chain

The chain is a wearing part that has to be lu­bricated regularly and to be changed at signs
of excessive wear and tear.The amount of
wear depends on maintenance and care as well
as on the circumstances of your ride (rain,
dirt, salt). Regular cleaning and lubricating can
increase the chain’s lifetime, nevertheless the
chain has to be changed when its wear limit is
reached.

Lubricating the chain

Diligent lubrication is important.The chain of
your Scorpion fs 26 is approximately 2.5 times
longer than a standard bicycle chain (approxi­mately 3.8 m).But it also lasts longer since a
chain only wears while bending at the sprock­ets and the chain rings.

Use a good chain oil that won't leave a sticky
film on the chain. The chain oil must not con­tain any aggressive chemical substances that
might affect the surface of the chain tubes or
chain idler.

Specialist stores sell biodegradable lubricants.
HP V

ELOTECHNIK recommends a DryLube-type

lubricant. This lubricant is purely based on
PTFE (Teflon) that keeps the chain clean and
dry.This way dirt simply falls off and the tubes
always stay clean.

It is important that you clean the chain with a
cloth before lubricating.Otherwise the fresh
oil washes the dirt that clings to the chain into
the gaps and the bushings where the dirt caus­es heavy wear.

Chain

Danger!Take care not to pour any oil on

the rims,brake discs or the tires.The brak­ing system could fail or the tires could slip
away suddenly.The oil affects the rubber of
your tires and can damage it.While lubricat­ing cover the surrounding area.

Changing the chain

The chain is one of the parts of the trike that
will wear out. This shows in a stretching of the
chain. Worn out chains do not fit the sprockets
and chain rings any more and wear them away
very quickly.

Check the chain for lengthening regularly.For
this purpose try to remove the chain from the

Only use chains that are suitable for the gear
system of your trike.Otherwise a precise gear
shifting is not guaranteed any more.Please
consult your dealer on this topic.He will also
assist you in checking your sprockets and chain
rings.A new chain does not fit a worn sprock­et or chain ring. We recommend rust resistant
Rustbuster-chains from KMC with smoothly
rounded edges.They also provide a good gear

delivers spare chains by the
meter via your dealer.For this purpose please
indicate the exact length of your chain or or­der it a little bit longer if you want to be sure
it fits.You will need approximately. 3,8 m of
chain.

The chain length has to be fitted so that the
arm of the derailleur is not fully stretched
when you shift on the big chain ring in front
and the big rear sprocket.The derailleur must
still be able to compensate a shortening of the
chain by 4 cm.Please also see the manual of
the derailleur manufacturer on the choice of
the correct chain length.

See that the joining link is not bigger in size
than the other chain links to avoid irregular
chain sounds. We recommend the joining links
by KMC.Every time you change the chain you
also have to apply a new joining link.

Make sure that any chain links in the chain are
not stiff,as this can cause some annoying and
not obvious problems with the gear system.

Make sure that you have not twisted the chain
180 degrees before joining it back together.

Caution!When you change the chain take
care that the new chain does not show any
sharp edges or burrs.

Caution!The chain has to be closed with a
special joining link or a chain riveting tool
that expands the ends of the rivet while riv­eting (R

OHLOFF revolver).A poorly joined

chain may break,you can come off the ped­als and fall.If you are in doubt please have
adjustments of the chain length or the
changing of the chain be done by your bicy­cle mechanic.

Chain tubes

40

37

Chain tubes

The chain protection tubes are made of a long
lasting plastic that features very low friction,
slow wear and good noise damping.The tubes
protect your clothes against the chain oil as
well as the chain against dirt from the road.

The upper tubes are fastened with an inter­changeable retention spring,the lower tube
runs through an adjustable clip.

The tubes are worn by the chain and have to
be cut at the ends and expanded again (or ex­changed) after 3.000-5.000 km approximately,
depending on the chain type and the overall
riding condition.You can extend this mainte­nance interval by turning the tubes by a quar­ter turn from time to time so that they do not
keep wearing out in the same place.

The intensity of the wear depends mainly on
the chain type. Please see also the instructions
on "Chain" on page 38.

In order to perform any work at the chain
tubes you'll have to open the chain and finally
close it again.Please see the instructions on
"Chain" on page 38.
The distance of the upper chain tube to the
chainwheel can be adjusted by sliding the tube
in the retention spring.It must be secured
with the rubber tube over the spring.

Expanding the tube ends

The ends of the tubes are expanded like a
trumpet so that the chain can enter smoothly
without friction and without making noises.

When the ends are worn out you can renew
them by expanding them again.Remove the
chain by opening the power link or open it
with a special chain riveting tool.Cut the worn
part of the tube exactly perpendicular with a
sharp knife.

Heat the last 5-10 mm at the end of the tube
with a gas burner, a hot air gun, or a candle
and turn it permanently until the colour of the
utmost edge turns from a dull black to a shiny
black.Now you expand the end with a proper
tool,e.g. the rounded grip of a screwdriver.
Quench the expanded end immediately with
cold water.

Take care that the tubes don't catch fire.At
any rate work in a place with sufficient ventila­tion.

Caution!Take care that the chain tubes
keep at least a 5 cm distance to the rear and
front derailleur when the chain is stretched
to the maximum,and that the tubes are well
fastened.If necessary you will have to short­en the tubes.If the end of a chain tube gets
into the rotating parts of the drivetrain the
drivetrain can be blocked and the chain
tubes may be destroyed.

Caution!The rear ends of the upper chain
tube have to be secured against moving with
a tight rubber tube over the retention
spring. Without the rubber tube the chain
tube may be dragged forward into the turn­ing chain roller or chainring and thus be
damaged by the chain.

Caution! Check the chain tubes frequently
if they are damaged or defective. Replace de­fective chain tubes immediately.If the chain
tubes are worn in the area of the retention
spring or tube mountings,the chain will
touch the retention spring,leading to failure
of the spring and mountings.As a result,the
chain tube can get into the drive train and
block it!

If the tube is too short after you have cut it so
that there is not enough protection anymore it
has to be replaced.You can buy spare tubes ei­ther as uncut tubes or already cut into the
correct length,complete with retention spring
from your specialist dealer.

Changing the tubes

In order to exchange single parts in the upper
chain tubes cut the old tube at the retention
spring at the chain roller and pull the remain­ing part off the spring. Now move the smooth
part of the new tube through the spring and
rubber tube, then expand the tube end as de­scribed above.

Changing the complete upper chain pr

o-

tection or the retention spring

Remove the bolt in the chain roller with an
Allen key 6 mm.Take off the chain roller,the
washer and the chain retention hook.

The end of the threaded tube in the frame is
protected with a plastic tube.

Take the retention spring off this plastic tube
and put on the new retention spring.Turn the
spring so that the retention springs run under
the spacer to the tubes and the wires lie bet­ween frame and chain tube;that way the spi­rals face outwards.

Push the bolt back through the chain roller,
the washer and the chain retention hook,se­cure the thread with Loctite and tighten the
bolt with 17-19 Nm. The recessed side of the
chain roller has to face to the frame.Make su­re the washer is placed between chain roller
and plastic tube / frame.

Changing the lower chain tube

The chain tube is connected to the mounting
plate by a rubber sleeve.For dismounting the
chain tube, grab the sleeve on its rear end and
pull it together with the chain tube to the rear.
The rubber sleeves will release the rear
tongue of the mounting plate then.Swivel the
chain tube sidewards.Having done that pull
the chain tube to the front to release the
sleeve from the front tongue of the mounting
plate. Replace the chain tube and mount it by
following the above steps vice versa.

The chain protection tube must be pulled backwards first to let
the rubber tube release the mounting plate.

Chain roller

39

Chain roller

The chain roller guides the chain below the
seat to the rear wheel and is an essential part
of the HP V

ELOTECHNIK No Squat design.It en-

sures that the suspension is not influenced by
pedaling.

Compared to other models the chain roller
has a big diameter and it has a higher area in
the middle to make the chain move as
smoothly as possible. Due to this higher area
the chain does not lie on the roller with its
sharp edged links but with the bushes in the
middle that work like small bushings.In addi­tion to a very low rolling resistance it also
supports a quiet chain movement.A chain re­tention hook between the frame and the chain
roller locks the roller at the bottom and keeps
the chain on the roller when you pedal back­wards.

The chain roller is not symetrically shaped;the
recessed side of the chain roller has to face to
the frame, the flat (logo) side outwards.

The chain roller wears slowly and gradually
shows a sprocket shape in the higher area in
the middle.When this middle area is worn
completely the links of the chain will run on
the roller.In that case you will notice that the
chain makes more noise while running and you
should change the roller. You can purchase the
plastic part without the bearing or the com­plete roller through your dealer.

The bearings must not be treated with a jet of
water from a high-pressure cleaner or with
solvents since this may destroy the sealings
and remove grease from the bearings. If the
bearings don't move smoothly anymore you'll
have to replace them.

Dismounting the chain r

oller

See the notes on changing the chain tubes,

page 40.

The chain roller is mounted with a special high
strength screw of the German strength grade

12.9 and it may only be replaced by a screw of
the same type and strength.

Caution! If this chain retention hook is
missing the chain may fall down.When you
start pedaling then the chain roller, the seat
or the frame may be damaged through the
chain.Please consult your local specialist
dealer in case this hook is missing.

Caution! The roller comes with two main­tenance free sealed bearings. The bearings
are exchangeable.Between the bearings
there is a spacer that keeps the correct dis­tance. If you forget to put in the spacer after
you have dismounted the bearings they will
be destroyed when you tighten the screw
while remounting them.

between the rear edges b

h

.If toe-in is checked

in unloaded condition,the proper tolerance is
2–4 mm (1/16”–1/8”). Then, the correct value
is reached under normal riding conditions with
the front wheels deflected by ca.20 mm.

It is important to measure the distances at the
same height of 25 cm (10“) above the ground,
as the front wheel are not exactly perpendicu­lar to the ground,viewed from the front of the
trike.Measuring at varying heights results in
measuring errors.

Front wheel alignment

Measuring toe-in

Both front wheels should be parallel to each
other, viewed from above the trike , compare
picture below.

The condition of the front ends of the front
wheels being closer together than the rear
ends of the front wheels (b

v

smaller than bh) is

called toe-in,the condition of the front ends of
the front wheels being further apart than the
rear ends of the front wheels (b

v

larger than

b

h

,) is called toe-out. The measures are taken

at wheel axle height on the rim sidewalls.
If the front wheel alignment is incorrect,you

will suffer excessive tire wear and increased ti­re drag.Check your front wheel alignment re­gularly.The proper tolerance on toe-in is 0–2
mm (1/16“).For correct measuring properly
trued wheels are required.

To check the toe setting turn the handlebars
into the neutral position,so that the wheels
are aligned straight forward.Measure the di­stance between the front inner or outer edges
of the front wheel rims and the rear inner or
outer edges of the front wheel rims 25 cm
(10“) above the ground.

Hold the rod-end with a wrench and loosen
the nut that is screwed against the rod-end.

Screw the rod-end into the tie-rod to enlarge
the distance b

v

between the front edges of the

front wheel.Screw the rod-end out of the tie­rod to decrease the distance of the front
wheel edges.

Adjusting toe-in

The front wheels are held by suspension struts
which can turn at the ends of the main frame.
The suspension struts are connected by tie
rods to the handlebar stem.

The rod ends consist of ball-and-socket bear­ings that can be screwed in or out of the tie­rod for length adjustment.

Length adjustment is done at the inner tie-rod
end,at the connection to the handlebar stem.
The outer rod end is screwed completely into
the rod and secured with threadlocker. Do not
try to turn this side of the rod end.

First make sure that the handlebar is aligned
perpendicular to the main frame tube. Identify
which wheel (or perhaps both wheels) needs
adjustments of the toe-in by measuring the
distance between rim wall and main tube on
the most forward point and on the most back­ward point of the rim (value a

v

and ahin the

picture). The distances should be roughly iden­tical for one wheel.

Remove the bolt that connects the inner rod­end to the handlebar stem,note the washer.

Danger!The rod-end must be screwed at
least 8 mm into the tie-rod.If it is screwed
out to far, the thread could tear out and the
trike could become unsteerable. This means
that with a standard length of the thread of
the rod-end of 24 mm,a maximum of 11
mm visible free thread length is allowed bet­ween rod-end and lock-nut.The lock nut
must be screwed tight to the tie-rod,other­wise the rod-end could loosen up or play
could develop.

Caution! Do not move the rod-end beyond
its limits,or it will be destroyed or get ex­cessive play.Always hold the rod end with a
wrench or secure the tie rod with a wrench
against turning when tightening the lock nut.

Align both rod-ends parallel to each other.
Grip the rod-end with a wrench and tighten
the nut against the tie-rod with 4–5 Nm.

On the other side of the track rod the rod
end is mounted on the underside of the sus­pension strut’s steering lever. Between strut
and rod end there is a washer and a spacer.
There is an additional spacer between screw
head and rod end.

Attach the tie-rod to the handlebar stem:First,
the screw is put through the hole in the stem
(from upside to downside).Then slide the
washer and the rod end onto the screw.
Finally, put on the self-locking nut.

Measure the toe-in as described above.Repeat
the adjustment process until you reach the re­quired toe-in setting.

Danger! Secure the thread of the bolt with
Loctite adhesive.Check all connections of
the steering system before every ride. If a
connection loosens,the trike becomes un­steerable which may lad to serious injury.

Caution! Make sure the washer is between
rod end and bracket to allow the full mova­bility of the rod end.

Rear suspension element

Rear suspension element

Changing the steel spring (DV-22)

You can buy the spring for the rear suspension
element in different spring rates at your dealer.

We recommend the following spring rates,de­pending on the overall weight:

up to 80 kg (176 lbs):450 lbs./inch
up to 110 kg (242 lbs):550 lbs./inch
up to 140 kg (308 lbs):650 lbs./inch

In addition to this,your dealer can also use
springs with other spring rates or special light­weight springs made of titanium.

In most cases the rate is printed onto the
spring.Pay attention to the correct imprint sin­ce the term "B650" that sometimes occurs
does not necessarily mean 650 lbs./inch!

Spring length:
DV22:83 mm (70-90 mm)

In order to change the spring you will have to
remove the rear screw and swivel away the re­ar frame.

Hold the main frame of your bicycle in a work
stand.

If there is a safety ring at the thread of the su­spension element move it to the end so you
can unscrew the adjustment ring completely
and then turn it to the outer position at the
end.Remove the slotted spring retention disc
at the other end.

Loosen the screws of the rear suspension ele­ment with two Allen keys and push the screw
out of the suspension element’s eye.

Move the rear swing arm down carefully.While
doing this,take care that you don't bend or
stretch any cables.

Remove the spring from the suspension ele­ment and put on the replacement spring.Make
sure the new spring has the same diameter
and length as the old spring and that it is sup­ported safely by the adjustment ring.

Put back the slotted spring retention disc on
the piston rod.If necessary,compress the
spring a little bit. The spring retention disc has
to match its support at the end of the suspen­sion element.

Danger! If the bicycle does not stand on
the ground while undoing the screws of the
suspension element the rear swing arm may
come down uncontrolled afterwards and
hurt you seriously. In addition to this the ca­bles of the gear system and the brakes may
overstretch and you will have to replace
them.Ensure that the rear swing arm comes
down in a controlled and gentle way by put­ting up a solid string or zip tie between the
main frame and the rear swing arm.

Danger!When the bicycle is standing on
the ground the frame and the swing arm co­me up against each other. Please make sure
that this happens in a controlled and gentle
fashion.Put a cloth between the contact sur­faces.Otherwise, if they come up against
each other uncontrolled your hands may get
caught between main frame,rear swing arm
and suspension element and your bicycle
may be damaged.

Maintenance and care

Secure the spring by tightening the adjustment
ring until the spring doesn't show any play any
more.If there is a safety spring ring,push it
back into the slot on the thread.

Move the rear swing arm back up and connect
the rear end of the suspension element with
the rear swing arm using the bolt.Lubricate
the bolt thoroughly.

Secure the screws of the suspension element
with threadlocker and tighten the screws with
6-8 Nm.

After having exchanged the spring you have to
readjust the spring preload as described in the
chapter on "Adjusting your new bicycle" on
page 17.

Cleaning and lubricating

Do clean the suspension element,especially
the polished piston rod,if it is dirty.Remaining
dirt and sand can damage the seals of the hy­draulic system and so shorten its life consider­ably.We recommend you to protect the su­spension element from dirt with an elastic co­ver that you can buy at your local dealer when
riding on dirty roads regularly.

From time to time grease the thread for the
spring pre-load with a drop of acid-free oil.
Thus,you can always turn the adjustment ring
easily by hand.Once a year you have to grease
the pivots of the suspension element.For that
purpose dismount the suspension element as
described under "Changing the Spring" on page

46.
Remove the plastic spacers and pull the metal

tube out off the bushing.Lubricate the bushing
and the tubes with grease.Finally remount the
suspension element.

Hydraulic dampers are affected by wear and
tear through normal use.It depends on the
usage of the trike,the amount of dirt on it and
the maintenance and lubrication.After 3000
km the damper must receive an inspection by
a trained mechanic, worn out parts or the hy­draulic cartridge can be replaced then.Due to
wear of the seals oil can leak from the damper.
The internal oil can become foamy. This may
lead to some noise when the damper is wor­king. This noise does not effect the function of
the damper. Only if there is no obvious dam­ping after the first 5 mm of travel,the damper
should be replaced.

Please also note the maintenance instructions
of the damper manufacturer provided with
your trike.

The bushings of the rear spring element need to be lubricated
once a year.

Customizing the front suspension

The Scorpion fs 26's front suspension can be
customized by different measures:

- adjusting the preload (see page 22)

- exchanging the elastomers or spacers

- exchanging the steel springs

- exchanging the stabilizer bar

- exchanging the damping elastomer bands
According to your order, the Scorpion fs

comes with standard suspension setup either
up to 90 kg or above 90 kg.

Standard suspension setup up to 90 kg:

- steel spring soft (red)

- 4 MCU elastomers 30 mm

- 1 spacer 30 mm

- stabilizer bar soft (white)

- low damping rate (elastomer bands 1,6 mm)
Standard suspension setup above 90 kg:

- steel spring hard (yellow)

- 4 MCU elastomers 30 mm

- 1 spacer 30 mm

- stabilizer bar hard (grey)

- low damping rate (elastomer bands 1,6 mm)
Enclosed for individual setup:

- 2 MCU elastomers 30 mm

- 2 spacers 30 mm

- 2 elastomer bands 1,7 mm,high damping rate
These standard setups can be customized.As

an example, you can find curves of different
options in the diagram. The cur ve shape shows
the characteristic of the suspension setup.

The characteristic is referred to as linear when
the curve of suspension force related to sus­pension travel forms a straight line. Force and
travel are related to each other by a constant
factor, called spring rate , throughout the whole
suspension travel.This is a typical characteristic
of steel springs.

The characteristic is referred to as progressive
(or rising rate) when the spring rate increases
with suspension travel.In the diagram, this re­sults in a curve with a left bend. Due to their
design,elastomers and air springs show this
characteristic (MCU elastomers show an al­most linear characteristic in the first part of
their travel,see cur ve nr.4).

Tuning your suspension bases on the choice of
the steel spring according to your usual load.
The soft spring moves the area of operation
to low rider and luggage weight,the hard
spring to high rider and luggage weight. The
suspension characteristic is not affected by
choosing another steel spring with different
spring rate. Varying the number of elastomers
and their relation to the number of spacers in­side the steel spring changes the area of oper­ation as well as the suspension characteristic.
It is allowed to have one or more blank spaces
out of the five spaces available for elastomers
or spacers.In this case the load during the first
part of the travel is only taken by the steel
spring and the elastomers only affect the sus­pension after the travel of the blank spaces is
used up.

Front suspension

Caution! Do not install more than two spa-

cers in one strut,otherwise the full suspen­sion travel can not be reached. Spacers
should always be installed at the top of the
stack inside the spring to give room for the
screw in the top cap.The setup must be si­milar in both suspension struts of your trike.

Caution!The suspension must be set up in
a way that avoids permanent bottoming out
(a clearly recognizable bumping into the end
stops).Permanent bottoming out may redu­ce the components' life time.

Maintenance and care

HP

If you use your Scorpion fs 26 under different
conditions and changing loads as well as on
good and bad surfaces,a setup with a progres­sive characteristic for the whole travel is rec­ommended to get a comfortable suspension
under all conditions of use.The elastomers
support the steel spring from the beginning.By
changing the relation between the number of
elastomers and number of spacers,you can in­fluence the suspension characteristic and the
maximum force the strut can bear before it
bottoms out.Examples in the diagram are the
curves nr. 1 and nr. 2 which show the standard
setups. They feature moderate progression and
increased maximum load compared to a single
steel spring.(Setup: spacer-spacer-elastomer­elastomere-elastomer)

Will your Scorpion fs 26 always face the same
load and only high quality roads,for example,
you may tune your suspension characteristic
to a more linear behaviour in the first two
thirds of travel and a high progression in the
remaining third.The linear par t provides very
high comfort.The progression at the end pre­vents the strut from frequently bottoming out
due to unusual high loads.

A characteristic like this (3) can be achieved
by a steel spring which is responsible for tak­ing all the load at first and will be supported
by only a few elastomers towards the end of
travel.(Example setup: empty-spacer-spacer­elastomer-elastomer)

To exchange elastomers or spacers, the end
cap and the preload adjuster (which is under
tension) must be removed.Having done so,the
steel spring and the inside elastomers and
spacers can be taken out.The lower support
of this suspension package is an axial bearing
which consists of three parts. This bearing or
its parts may stick to the spring (caused by lu­bricant).Make sure this axial bearing is mount­ed under the spring in the correct order
(washer-bearing-washer) during reassembly.If
there are elastomers left in the strut,a thin
needle pricked into will help to remove them.
Now the springs,elastomers, and spacers can
be recombined. When screwing in the preload
adjuster disc, make sure it is aligned straightly.
It must be screwed in against spring force,
therefore the assistance of a second person
might be asked.

Caution! Make sure that the axial bearing
was mounted correctly between spring and
support plate inside the strut during assem­bly.A missing or wrongly placed axial bearing
may damage the suspension strut or lead to
steering heaviness.

Stabilizer bar

To decrease body roll while cornering,the
Scorpion fs 26 is equipped with a stabilizer bar.
As long as the spring deflection height is the
same on both front wheels,the stabilizer bar
has no effect.If one single wheel is moving up­wards (e.g.the outside wheel due to the dy­namic forces at high speed cornering),the sta­bilizer bar works as a torsional spring and in­creases the spring rate of this wheel.Besides,
it transmits parts of this wheel's load to the
opposite wheel's suspension strut which then
supports the higher-loaded wheel.As a result
of this the single-sided suspension on bad qual­ity roads will be harder compared to both
wheels moving at the same time in the same
direction.

If you prefer a very comfortable ride, it is pos­sible to mount the soft (white) stabilizer bar in
spite of high loads and appropriate spring set­up.However,the Scoprion fs will lean more
outwards in fast driven corners.

If you prefer a sporty style of riding whith a
minimum of body roll,you may also use the
hard (grey) stabilizer bar with a soft spring set­up.

To remove the stabilizer bar, simply unscrew
both bolts which connect the stabilizer bar
brackets to the frame plates.Now the stabiliz­er bar can be pulled out of its bushings in the
wishbones. The aluminium brackets can be re­moved afterwards. Assembly is done in re­versed order.

Removing and disassembling the sus­pension struts

To provide a long lasting,faultless function of
the front suspension,the struts must be main­tained regularly according to the service plan
on page 66. During design, great importance
was attached to keep the bearings of the front
suspension free from dirt and moisture.That's
why the struts are equipped with a shock boot
with vent holes situated inside the frame's
steering tubes. This makes sure that predomi­nantly clean and dry air is exchanged.
Depending on the area and conditions the
Scorpion fs 26 fs is operated in and under, dir t
and moisture could nevertheless reach the
bearings inside. Hence it is neccessar y,espe­cially after riding under rainy and snowy or of­froad conditions,to check the struts for dirt
and clean them.Under extreme conditions,we
recommend to shorten the maintenance inter­vals given in the service plan.

Front suspension

Caution! Before inserting the countersunk

bolts,make sure the brackets are fitted pla­nar to the frame plates and the hole centers
are aligned to each other.Otherwise you
may damage the threads and destroy the
brackets.

Caution! Use aging-resistant, lithium soap
based grease to lubricate.Never use grease
containing solid lubricants such as molybde­num disulfide or zinc sulfide.

Danger! While adjusting the front suspen­sion,never load the tricycle, e.g. by resting
on the seat or loading the racks when your
hands or tools are close to the suspension
struts.Your hands may be bruised when the
suspension compresses.

Maintenance and care

HP

To clean the suspension strut occasionally,
clean the shock boot and slide it down com­pletely. Clean the stanchion tube thoroughly
with a soft,dry cloth.Apply a thin layer of
grease or suitable oil.Finally, slide back the
shockboot to its original position.

To maintain the suspension strut according to
the service plan or to exchange the elastomer
bands for damping adjustment,it has to be re­moved and disassembled.Therefore, fit the
Scorpion fs 26 to a workstand in a way that
provides easy access to the respective front
wheel.Remove the front wheel.Remove the
brake caliper according to the manufacturer's
manual.Unfasten the fender (see page 56).
Demount the stabilizer bar as described
above.

Unscrew the outer rod end of the track rod
from the suspension strut.The lower collar of
the rubber cap must be slid upwards to access
the self-locking M6 nut.

Unscrew the hex bolt M6x40 A at the strut's
lower end,which connects the strut with the
wishbone.

Now remove the end cap B at the suspension
strut's upper end.Unscrew and remove the
clamp C as well as the spacer D, F,cap E and
spacer F below.Pivot the strut in a way that it
may pass the wishbone and push it downwards
to slide it out of the elastomer bearing G.In
case the strut won't pass the wishbone,you
have to dismount the wishbone's rear pivot
point.

Caution! Never clean your tricycle and
especially parts of the suspension with a
pressure washer or steam cleaner.These de­vices remove lubricant and transport dirt in­to the bearings which causes higher wear.

Caution! Always secure the wishbones or
track rods by tying them to the frame (e.g.
using zip ties) to make sure they won't move
until their stop.This would damage the sphe­rical plain bearings and rod ends.

long K with thick sealing ring L - screw head
A). Tighten the screw with a torque of 9-10
Nm.By doing this, the piston is locked at the
lower end of the suspension strut in its cor­rect position.

Front suspension

A hammer punch on the bolt releases the piston inside the
knuckle.

Remove the hex bolt A and slide the stan­chion tube 3 (golden) out of the knuckle.

The elastomer band 8 can now be removed.
Clean the sliding surfaces of the stanchion
tube and the bushings 4,as well as the inside
of the knuckle 2.Use a clean soft cloth. If
there is noticeable play in the bushings or if
the bushings are damaged,please contact your
dealer. Lubricate the surfaces of the clean
bushings 4. Check the proper position of the
bottom out elastomer 5 inside the knuckle.
Apply a thin layer of grease on the stanchion
tube 3.

Applying grease to the bushings.

Caution! We recommend to use CONCEPT-
LUBE available from HPVELOTECHNIK for best
performance. You can also use aging-resist­ant,lithium soap based grease to lubricate.
Never use grease containing solid lubricants
such as molybdenum disulfide or zinc sulfide.

Maintenance and care

If you are not able to fasten the screw (i.e.it
can be turned on and on),you have to disas­semble the springs (see "Customizing the front
suspension",page 48, the axial bearing 7 may
remain inside) and fix the piston with a long
hex key size 5.

When mounting the rod end at the suspension
strut,take care to assemble the parts in the
correct order, from upside:screw head,steer­ing lever, washer 6,spacer 6 mm length,rod
end,self-locking nut M6. In case you have re­moved the rubber cap, circlip pliers will help
you to reassemble.

Adjusting the front axle geometry
(information for bicycle mechanics)

The Scorpion fs 26 is equipped with adjustable
wishbones.By adjusting the rod ends on the
wishbones,the required axle specifications can
be met.During assembly in our factory,the
front axle was adjusted correctly. In case of re­placement of worn-out or damaged parts the
front axle needs to be readjusted. In unloaded
condition,the following adjustment values
must be met:

- toe:2–4 mm toe-in

- camber angle:+0,5° (+0,5°/-1,5°)

- max.difference in camber angle left/right:0,5°

- caster angle:76,7° (+/-1°)

Exploded view of the suspension strut interior

Caution! Use threadlocker (e.g.LOCTITE

243) with all bolted connections that are
not equipped with self-locking nuts,else the
connections may become loose.

Caution! Always check the front axle speci­fications after accidents or unintended
events such as riding through a deep road
hole or contact with the curb at higher
speed as well as after replacing axle compo­nents.An incorrect adjustment can lead to
increased tire wear and uncontrollable han­dling.

For measuring,the Scorpion fs 26 must stand
on a plane, non-inclined floor.

To measure the caster angle, the frontwheels
must point straightforward. Attach a protrac­tor to the front side of the fender bracket.
Align the protractor perpendicular to the
ground.Make sure the protractor only touches
the fender bracket and not the frame’s head­tube.

HP

Velotechnik

Reattach the foam tube that covers the large
rod ends and a short part of the oval wish­bone tube. Mount the rod ends to the frame
brackets.

To finish the front axle setup measure and ad­just the toe as described in "Front wheel align­ment" on page 43.

Front suspension

54

To measure the front wheel's camber angle
position a long square next to the wheel coni­cident with the wheel axis.Set the lower dis­tance between rim wall and square to 40 mm
(s

u

= 40 mm).The upper measure sobetween

rim wall and square should be 36 mm (+0,5°
positive camber) now and must be in a range
of 32 (+1° positive camber) to 48 mm (-1°
negative camber). The difference between the
measure s

o

on the left and right wheel must

not exceed 4mm.
For adjusting works,the trike should be

mounted in a workstand,best upside down.
The stabilizer bar must be disassembled.

To adjust the front axle both rod ends of one
wishbone must be disassembled from the
frame. Loosen the counter nuts and screw in
or out the rod ends according to the table on
the left.Values in between can be interpolated.

Check the values after provisionally reattach­ing the wishbone and wheel on a plane floor.
Repeat the adjustment if necessary.

After having reached the correct setup,fasten
the counter nuts of the rod ends with 4–5
Nm.

The bushings are exchangeable.For that pur­pose you will have to dismount the rear swing
arm and send it together with the axle via
your specialist dealer to HP V

ELOTECHNIK.After

installation the bushings are machined to ad­just them.

Unscrewing the axle bolts

Before being able to unscrew the axle bolts a
possible rear rack must be disassembled.To do
so both lower screws of the rear rack must be
unscrewed completely, both upper screws
must be loosened. Then, the rear rack can be
swivelled upwards.

In case the rear swingarm is to be dismounted
completely you can prevent the axle from
turning by inserting a thin metal rod in the
hole of the axle through the hole in the rear
swing arm under the axle.

Swing arm pivot

Swing arm pivot

The rear swing arm pivot comes with mainte­nance free bushings. They feature a self lubri­cating system with Teflon par ticles.The bush­ings sustain a very high load and they show al­most no wear.

In case you notice play or a creaking noise at
the rear swing arm please check the two
screws that keep the axle in the frame.They
have to be secured with threadlocker.

Tightening torque:17-19 Nm

Danger! If the screws at the axle are not
tight enough this leads to play and noises
when the spring compresses.In extreme
cases the swing arm may come loose which
leads to a serious fall.If the screws are too
tight the thread of the axle may tear out or
the screw may be damaged.

Caution!There has to be a big washer be­tween the main frame and the end of the
bushing else the bushing is not able to func­tion without play and the frame will be da­maged.

You can prevent the axle from turning by inserting a thin metal
rod in the hole of the axle.

Front mudguards

The front mudguard mounting is attached to a
bracket on the suspension struts.

The sheetmetal mounting bolts (facing the
wheel) must be fastened with 6–8 Nm.

To remove the mudguards unscrew the sheet­metal mounting bolts until the sheetmetal can
be pulled out.Secure or remove the sheetmet­al mounting bolts.

Mudguards

Mudguards

Mudguards are exposed to very strong vibra­tions at suspended wheels which may cause
them to break.Please check the stays and
mountings of the mudguards regularly for their
position and check the mudguards themselves
for cracks or deformations.Replace damaged
mudguards immediately.

If the wheels are removed, the tricycle must
not rest on the front mudguards. Loosen the
screw between mudguard mounting and
knuckle to remove the mudguard.

The front mudguards are adjustable in height
to accommodate different tire heights by
means of the slotted holes in the mudguard
mounting.

After having performed service work or after
replacing mudguards check if the wheels turn
freely.There has to be a distance of at least 7
mm between mudguard and wheel.

Check whether the suspension can still be
completely compressed with mounted mud­guards. The mudguards, stays,mountings, and
screws must not touch other parts under
maximum compression.

Danger! If branches or other obstacles get
caught in the wheels while riding and are
moved around they may drag the mudguards
along. The mudguard can possibly fold up be­tween frame and tire and hence block the
wheel,which may lead to a serious fall.If you
hear any unknown noises while riding stop
immediately and remove anything that might
cling to the mudguards or the wheels.

Caution!You must not mount additional
parts like rear lights or reflectors to the
mudguards since those may break then.

Danger! Make sure that the sheetmetals
are fastened with the correct tightening tor­que

(

6–8 Nm) and the screws are secured
with threadlocker. Frequently check the as­sembly. If a sheetmetal becomes loose,the
fender may be caught by the wheels and
lock the wheel or flung away.This may lead
to serios injury or fall!

Seat cushion

Seat cushion

The standard seat cushion consists of a 1,4 cm
thick layer of flexible EVA foam.This is a black
foam material with closed cells that is also
used in the production of high quality camping
mats.It feels very comfortable without appear­ing too soft or spongy.It is waterproof so you
can dry your seat with a sweep of your hand
in case your bicycle has become wet.

Caution! Never expose the seat cushion to
extreme heat or focused sunlight.The mate­rial warms up considerably.The heat may
melt the glue of the Velcro.The seat cushion
can be damaged when the rays of the sun
are bundled through a lens.Take care to nev­er leave any bubble wrap on the seat in the
sun. The air bubbles in the film act like a
burning glass and shrink the seat cushion.

Caution! The seat cushion is fastened with
Velcro and you can take it off.For this pur­pose it is important not to simply grab the
foam and take it off since the Velcro could
come off.In order to take off the seat cush­ion lift up the upper part a little bit from the
seat. Then you grab the cushion on both
sides together with the end of the Velcro
that sticks out slightly and remove the cush­ion slowly. In case the Velcro comes off fas­ten it again with a good glue.

For better ventilation,the Airflow Cushion is
available as accessory.This cushion consists of
several layers:A rigid mesh and a soft mesh,
which provides for an approximately 1 cm
thick air cushion with excellent circulation.
These two layers are wrapped up in a cover
that consists of fine mesh like it is known from
high quality rucksacks.

You can wash the Airflow Cushion at 30°
centigrade and it dries very quickly.

The seat cushion suffers from wear by con­stant use.The mesh parts under punctual pres­sure can be pressed together permanently af­ter some time of usage. In order to still pro­vide a good riding comfort,the Airflow
Cushion features additional rigid mesh padding.

Raincover

To keep the seat dry when your tricycle is
parked you can additionally purchase a rain­cover.It can be carried in the optional
Microbag or in the bag the ErgoMesh seat is
equipped standard with.

Caution! Don’t sit down on the raincover.
It may get hurt.

HP

Velotechnik

Wheels

The correct air pressure is decisive for
smooth running and a good protection against
punctures. The maximum pressure is printed
on the sidewall of your tire.You might find an
indication of the minimum required pressure
on the sidewall of the tire as well.

Since the tubes in the tires gradually loose air
you should check the air pressure before
every ride.

The tubes come with Presta valves (also called
french valves).They are very airtight and easy
to pump up.

To do so, first screw off the valve cap. Now
you see a small threaded rod with a knurled
nut that comes out of the valve.Loosen the
knurled nut as far as it is possible.

To pump up the tire and check the pressure
you need a pump with a gauge,preferably a
solid floor pump.Put the knob of the pump on
the valve,push it completely on the valve and
then retract it a little bit.Now you can pump
up your tire easily.

After you have pumped up the tire to the de­sired pressure pull off the pump knob.Secure
the valve by turning the knurled nut on the
threaded rod properly against the valve body.
Finally put on the valve cap again.

After you have exchanged the tires please
check if the wheels turn freely and check the
minimum distance between mudguards and
frame.

Scorpion fs 26

When you exchange tires please note the
maximum width limit of 50 mm (approximate­ly. 2 ").On the front wheels you have to use
tires of ISO size 406 (20").On the rear wheel
you have to use a tire of ISO size 559 (26").
The tire width possible at your bicycle de­pends on the size of your rims.Please ask your
local dealer.

Before pumping up the tire,you have to unscrew the little
knurled nut on the valve.

Danger! Never pump up your tires beyond
the maximum pressure.The tire may burst
while riding or come off the rim,which may
result in a serious fall and injury.

Danger! Check your tires for damage on a
regular basis.You should exchange tires with
worn threads or damaged sidewalls.
Damaged rim tapes have to be exchanged
immediately. Damages at the tires may lead
to a sudden burst of the tire and thus result
in a serious fall and injury.

58

Wheels

Scorpion fs 26 S-Pedelec

You are only allowed to exchange tires mount­ed as standard with tires including design ap­proval of the following size:

Front wheels

● ETRTO 40-406

● ETRTO 47-406

Rear wheel

● ETRTO 40-559

● ETRTO 47-559

The tires need to feature a speed index that
covers the maximum speed of 45 km/h (at
least B).Additionally they need to feature a
load index according to the maximum permit­ted axle load (front:28, rear 26).These indexes
are shown on the tire’s sidewall.

For tires 47-406 und 47-559 “Schwalbe
Energizer“ (series tires) the recommended
pressure is 5 bar.When using other tires plea­se pay attention to their maximum allowed
pressure.

Spok

es

The spokes of the wheels connect the rim to
the hub. They transmit the braking power of
the disc brakes,and in addition they transmit
the pedal forces at the rear wheel.

The tricycle requires a high spoke tension
(> 1000 N) as the wheels have to bear high
side loads.Any damaged spokes must be re­placed immediately.

Maintenance and care

HP

Velotechnik

59

Danger!Take care that your spokes are al­ways in perfect condition and the spoke ten­sion is balanced.Do not ride with wheels
that run untrue or wheels with loose or
missing spokes.These faults may lead to a
total failure of the wheel while braking and
result in a serious fall!

The wheels are fastened with a quick release
mounting and therefore they are susceptible to
theft.For this reason always lock the wheels
along with the frame to a solid object when
you park your bicycle somewhere .

To remove a front wheel,loosen the bolt in
the locking part at the inside of the knuckle at
least 6 mm.Pull the locking part away from the
knuckle. Pull the wheel a few mm away from
the knuckle and slide the axle through the slot
in the knuckle.

Take care not to bend the brake disc .When
reinstalling the wheel,slide the disc carefully
between the brake pads and take care not to
damage them. Tighten the screw in the locking
part with 8–10 Nm.

Taking out the front wheel after loosening the screw in the
locking part.

Caution!To true up the wheels you need
special skills,please have this work done by
an experienced bicycle mechanic.

Cleaning and conservation

The frame of the Scorpion fs 26 has a high
quality and environmentally friendly powder
coating. The surfaces of the aluminum par ts are
either polished or anodised. Threads and tech­nical contact areas can be unfinished and must
be protected with wax.

To keep the surfaces brilliant over many years
and to protect them effectively against corro­sion the bicycle has to be cleaned from dirt
and then conserved.

Dried sweat but also environmental influences
such as air pollution,dirt on the roads and es­pecially grit affect the parts,and not only may
this cause flaws but also serious structural
damage of the parts by corrosion.

In contrast to a widespread belief particularly
the "non-rusting" aluminum is dramatically af­fected by grit! This kind of damage may not be
visible in the beginning but it leads to a serious
danger when the part breaks.
Clean and conserve your bicycle diligently!

Bottle cage Cleaning and conser vation

Water bottle cage

Water bottle cages can be mounted using a
special bracket behind the seat available from
HP V

ELOTECHNIK.

The derailleur tube at the front of the frame
comes with threaded inserts M5 for an addi­tional water bottle cage as well.

An useful alternative to water bottles are sys­tems with a "water bag" and a drinking hose,
e.g. from S

OURCE or CAMELBAG.You can simply

strap them behind the seat or on the rear
rack.

Maintenance and care

HP

Velotechnik

The best things to clean your bicycle with are
warm water and a soft cloth.If your bicycle is
very dirty first take a wet sponge to soften the
dirt and then remove it.In case of bad grease
or oil stains you should use a special cleansing
agent for bicycles in addition.

While cleaning your bicycle check it for any
cracks,scratches, deformations, damaged parts,
loose spokes etc.If you are in doubt please
consult your local bike shop.

In case of small scratches at the surface of the
powder coating of the frame or the surface of
the seat you can simply polish them away.You
can buy a special polishing agent for epoxy
resins at a specialist dealer for boat building.
Do not use a polish for metal!

After cleaning the trike,dry it and treat the
paintwork and the metal surfaces with wax.
You can purchase this wax from your local
bike dealer as a convenient spray.

The wax passes moisture and flows into tiny
gaps and pores. After some minutes the sol­vent evaporates and leaves a dull and glutinous
film.Now polish the waxed parts of your bicy­cle with a soft cloth to make it real shiny.

Do not only wax the frame but also the
spokes,hubs,screws and nuts etc.You can also
conserve the chain with wax spray after lubri­cating it,see also the chapter on "Chain", page

38.
The frame has small holes for ventilation that

prevent condensation in the frame.These
holes must not be sealed.However, moisture
may enter the frame through the holes.
Therefore protect the inside of your frame by
applying wax spray through the holes.

Protect the parts where cables or chain tubes
may scratch the frame.You can buy special
stickers at your bike dealer or extra strong
transparent tape at your do-it-yourself-store.
That way you avoid scratches in the powder
coating and coating coming off.

Caution! Do not use any cleansing agents
that scrub or are chemically aggressive since
they affect the paintwork.Before using any
cleansing agent please test it at a part of
your bicycle that is not immediately visible.

Caution! Do not use any high-pressure
cleaner.The strong jet of water goes through
the seals of the bearings,blows away the
lube and causes corrosion of the bearing
parts and the chain. In addition to this it may
damage stickers.

Caution! Any damage of the paintwork has
to be cleaned from rust and repaired imme­diately, else the damaged part in the frame
gives way to corrosion that nests in the sur­rounding paintwork.This can result in dam­age of the frame.

Caution!Take care that after folding the
trike there are no par ts rubbing against the
frame.This may damage the paintwork.

Storing the bicycle

Before storing your bicycle over a longer peri­od of time, e .g. during winter, please take care
of the following steps:

● Clean your bicycle and protect it from

corrosion as described in the chapter on
"Cleaning".

● Store your bicycle in a dry and warm place.

● Avoid direct sun and storage close to the

heating since it affects the rubber of your
tires.

● Choose the smallest sprocket and the

smallest chain ring. That way the cables are
in the most relaxed position.

● The tubes of your tires loose air when

standing over a longer period of time.If the
bicycle then rests on flat tires the tires may
be damaged. Therefore hang up your bicycle
or check the air pressure regularly.

The winter months are a convenient period of
time for the annual service since then you
won't have to wait long for an appointment.
Many dealers offer special prices for the win­ter check.

Screws and bolts

Screws gradually settle in and hence they can
come loose.Therefore check the screws and
bolts regularly if they are tightened appropri­ately with a torque wrench.

In the following table you will find the pre­scribed tightening torques,they refer to
greased screws!

The grease also prevents your screws from
seizing in their threads so that they won't un­screw anymore . In particular, screws made of
stainless steel are susceptible to this and
therefore have always to be put in with grease.

Do use high quality acid free grease,if possible
a lubricant with added solid particles like
Teflon or MoS

2. Their ingredients still work

properly after the thinner grease has been re­moved from the contact surfaces.

Alternatively you can use threadlocker that
you apply to the screw before you put it into
the thread.

Always check the screws very diligently for
signs of corrosion.Rust at the screw heads
may also lead to the screw seizing in the
thread. When the metallic and shiny coating of
galvanised screws comes off and discloses dull,
gray-brown steel you have to exchange the
screw.

When you exchange screws please only use
screws of the same type.Screws come in dif­ferent strength classes.Please only use gal­vanised screws of the same type and strength,
corresponding to the German strength class

8.8 or stainless steel screws grade A2-70,
when not given any other recommendation.If
you are in doubt please ask your specialist
dealer.

The service inter vals given in this Warranty
Pass refer to an average use and a riding per­formance of 3.000 km per year.

When you ride more kilometres per year or
often ride under bad conditions like rain,grit

In order to measure your riding performance
we recommend to use a bicycle computer.

does the completed Warranty Pass record the
maintenance works for the validation of your
warranty but also does it prove the care and
the value of your bicycle - a good thing to
have when you are going to sell your Scorpion
fs 26 one day.
