the intended use.
The Gekko fxs is a bike 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.
The Gekko fxs allows children and teenager
with specic handicaps (see indications) to
gain individual mobility. Physiotherapy gets
supported, to hold up and keep balance
is trained as well as the coordination of
movements.
The power transmission takes place in a
reclined position. Actuation occurs by a
rotation that the leg muscles transmit on
the pedal cranks. An optional electric motor
can give support.
Using your bike on public roads is only
allowed if it has been equipped with the accessories that are required by the applicable
trafc regulations of the country in which
you are using it.
Never drive without holding on! Before
your rst ride, read the chapter “Riding
a recumbent tricycle” on page 12 and
get carefully used to the different vehicle
performance.
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.

Load capacity
The maximum load (rider + luggage) is
100 kg (220 lbs). The maximum total weight
(bicycle + rider + luggage) is 130 kg
(286 lbs). The lower limit is valid. With a
coupled trailer, the maximum total weight
must not exceed 130 kg (286 lbs).
Carrying luggage
Luggage transport is only allowed with the
special racks designed by HP
Rear rack on Gekko fxs
Danger! Additional loading can
inuence the handling of your tricycle considerably. If you plan on riding with heavy
luggage we advise you to make a test ride
on a street with no trafc to get used to
the new situation.
Velotechnik.
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
tricycle panniers. Take care that your luggage
does not cover the lighting system and the
reectors of your tricycle and that they stay
fully functional.
Maximum load for carriers:
The maximum load on the rear rack is 25 kg
(55 lbs).
Final assembly
Your tricycle has been delivered to your
specialist dealer only partly assembled.
Your dealer has to have carefully nished
the assembly, perhaps altered the specica-
tion of your tricycle to meet your special
requirements and has to have performed
a test ride. Please make sure that this predelivery 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 74.
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 tricycle by
positioning the centre of gravity of the luggage as low as possible, so pack heavy items
in the bottom of your panniers.

General safety instructions
Bolts and nuts
Attention! Screws must be
tightened with prescribed tightening torque.
In this manual tightening torques are given
in „Nm“ (Newton meter). 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 nd tables with
the prescribed torque settings on page 88
and 89 in this manual.
Screws gradually settle in and hence they
can come loose. Therefore check the screws
regularly if they are tightened appropriately
with a torque wrench.
In the tables on page 74 and 75 you will nd
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 Teon or MoS2. Their ingredients still
work properly after the thinner grease has
been removed from the contact surfaces.
Alternatively you can use thread locker e.g.
loctite, 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.
Safety instructions
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.
Danger! An incompletely or improperly closed quick release can result in
parts coming loose and hence in a crash,
possibly resulting in serious injury.
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.
HP
Velotechnik

Page 10
General safety instructions
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
(33 – 40 lbs). In its nal position, the lever
should come 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
rmly xed: Lift each wheel several inches
off the ground and give it a slap onto the
tire from above. A properly xed 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
Pitlock) that can only be opened with a
special tool. For this please consult your
local specialist dealer.
The rst miles
The rst 300 km (186 miles) are important
for breaking in the tricycle. During the rst
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 rst service. Please
record this rst service and the works
performed in the warranty pass on page
77. This rst service is the prerequisite for
further use of the tricycle and for your
warranty claims.
Danger! Check the proper setting
of quick release levers always before riding,
especially when the bicycle has been unattended.

Legal requirements
When you ride your tricycle on public
roads it must comply with national legislation and guidelines. They will vary from
country to country.
In general, there are minimum standards for
brakes, reectors and lighting systems, as
well as usually a general duty to ensure that
your vehicle is in roadworthy safe condition.
There will also be a duty to ride in a safe
and responsible manner. If you ride your
HP
Velotechnik tricycle in trafc you should
be sure to observe all the applicable laws
and regulations.
In most countries, including Germany and
the UK, two independent braking systems
are required. Do not ride with only one
brake working! Please contact your local
dealer to nd out about your legal obligations.
In the scope of German StVZO your equipment has to meet the following requirements:
• two functional, independent brakes
• a dynamo or battery driven lighting sys-
tem with a white headlight aiming
forward whose beam center touches the
road 10 m ahead
• a red taillight and a red rear reector
which may be combined
• at least one white reector aiming for-
ward and a red large area reector with
“Z” label aiming to the back
• two yellow reectors attached to the
spokes in every wheel; may be substituted
by tires or rims with white reective ring
• yellow pedal reectors on both sides for
the pedals
• a bell
By default the Gekko fxs is equipped accordingly to the current valid StVZO.
As an addition, we recommend to mount a
ag on a pole for better visibility in trafc.
You can nd a bracket for the pole at the
rear rack or the rear light mount.
The safety equipment on your tricycle must
be checked before every ride and maintained in proper condition.
Trafc regulations may change. Please check
currently valid regulations or ask your
specialist dealer.
In Germany, children under the age of eight
only may use a bicycle on sidewalks and
under adult supervision. Take especially care
of pedestrians.
No alteration of parts
Attention! You are not allowed
to perform any work on the parts of the
tricycle, especially frame, fork, handlebar and
seat, which might endanger their solidity.
These works include drilling holes, welding,
brazing, paint methods that add heat or any
other chemical treatment. If any of these
works is done improperly it may result in a
loss of strength by direct damage or increased susceptibility to corrosion.

Frame number and identication
marks
The frame number is placed on the one side
of the steering tube. If needed, an additional
identication number can be engraved at
the other side of the stering tube.
However, we recommend to use adhesive
stickers for additional identication numbers.
Position for identication mark on the Gekko fxs
Added parts and accessories
Attention! 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, handle-
bar ttings, bottle holders, etc. may impair
your safety due to additional loading or clips
with sharp edges.
Additional accessories may impair the function of your recumbent tricycle. 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 wheels
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 tricycle 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.
Replacement of parts
The replacement of parts relevant for safety
(especially brakes, lighting system, stem,
handlebar, knuckle, drive train) may only be
done with original parts by a bicycle mechanic, since it requires a certain degree of skill,
suitable tools and mechanical aptitude.
Any technical change you perform on your
own is at your own risk! This can also result
in the loss of any warranty.
Danger! If any part is deformed
(e.g. due to an accident or overload), especially frame, knuckles, handlebar, seat
mountings, pedals, cranks and brakes, it is
not allowed to use it any further or repair
it. Do not try to straighten bent parts. You
must replace them for your own safety. If
you do not replace a damaged part it can
result in a total failure of the part and you
may be seriously injured!

Riding a recumbent tricycle
Learning the new riding technique
Your new tricycle has been assembled by
your dealer and adjusted together with
you as described on the pages 15 and
following in the chapter „Adjusting your
new tricycle“. Before you sit down on your
tricycle and enjoy your rst 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
Handling instructions
riding position. Make sure that you and all
other future users of this tricycle will have
read this manual carefully prior to the rst
ride. If you are in doubt please consult your
local dealer.
Before the rst 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 trafc. Before you ride the tricycle in trafc you must master the handling
completely.
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 using a pedal binding system like
clipless pedals or toe clips and straps.
Keep all three wheels on the ground while
riding. If you are cornering too fast, your
tricycle 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 inuence the steering
of the tricycle.
Practice cornering away from trafc to learn
what speed is safe at a specic turning angle.
If you lift up a front wheel, immediately
steer in the opposite direction to bring it
safely back to the ground.
Attention! When getting on and
off the tricycle, make sure to avoid pulling
at the handle bars or stepping on the tie
rods. To get off the tricycle, 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
rmly at the handlebars, the steering can
be damaged.
HP
Velotechnik

Danger! Please be aware that due
to your low seat height other road users
may notice you very late. Ride anticipatory
with this in mind.
This is especially important while riding in
darkness. You yourself have a much better
view than others perceive you. Ride defensively. We recommend mounting a well visible
and reecting ag to the tricycle while using
it in trafc. Find more information about
lighting systems on page 43. Please ask your
dealer for more information.
Page 15
Riding a recumbent tricycle
How to ride correctly and safely
Attention! Always carry your
tricycle over stairs and curb stones. Do
not ride through big road holes. Especially
when road holes are lled with water it is
very difcult 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 rst, the damage may
be unnoticed. Please check your tricycle
immediately for deformations and cracks. If
you are in doubt please consult your local
dealer.
Do not ride freehand
Danger! In order to ride safely
you have to keep both hands at the handlebar. Even when signalling 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.
How to ride correctly and safely
Always adjust your speed to the trafc, 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.
most attentive car driver may not see you
due to your low riding position.
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 ts well. Protect yourself
by wearing special sports clothing that ts
tight and is reective. 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 special pedals
The Gekko fxs comes with heel support
pedals by default.
If you wish, you can equip your recumbent
tricycle with clippless pedals, ergonomic
safety pedals or ergonomic pedals with
lower leg xation. To accomodate persons
with different physical impairments, the ergonomic versions can optional be choosed
for one side or both side.

Riding a recumbent tricycle
Slowly increase the strain
We recommend you to perform only short
rides without much power during the rst
weeks. Always use a low gear and ride with
a high pedalling 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 rst. 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 pedalling. The good support
of the back sometimes misleads to putting
the full power of the legs in the pedal, simi-
lar to the leg training machines in a tness
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.
Please contact your physician if you have
pain over a longer period of time.
Also, a wrong adjustment of the front boom
to the leg length (in most cases too short)
can lead to pain in the knees. Advices for
increasing the training can be found in a lot
of cycling books or magazines. Your pedalling 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.

Adjusting your new tricycle
Your position on the recumbent bicycle is
essential for your riding comfort, well-being
and efcient cycling. Therefore you should
adjust the frame, seat, handlebar and suspension to your individual requirements.
Find detailed information about the possibilities of adjustment on the following pages.
Danger! All procedures described
here require 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
trafc. If you have any doubts please contact
your local dealer.
Basic adjustment of the frame length
For the basic adjustment of the frame length
for different body heights, the rear frame
tube and the seating have to be adjusted
with the blue quick release levers.
Adjusting range of the Gekko fxs
If your tricycle is equipped with the optional
front boom quick adjust, please read the instructions in the separate manual in addition
to the following instructions.
The Gekko fxs can be adapted for riders
between 1,20 m to 1,80 m (3'11" to 5'11").
The basic adjustment takes place by changing the frame length.
In order to adapt the bicycle as closely as
possible to your body dimensions and to
nd your ideal position you need to adjust
the front boom, seat and handlebars.
If you open these quick release levers of the
OrthoFlex-seat, seat depth and frame length
can interdependent be slided in or pulled
out.
First, open the seatback quick release lever
that allows to adjust the seat angle. Then,
swivel the seatback to the front.

tely adjusted together with the rear frame
to the riders size (see page 15). With a
quick release, the seat angle can be adjusted
between 48 and 64 degrees.
The contour of the seat can be adapted
to the natural S-shape of the spine. The
support of the pedaling forces takes place in
the area of the lumbar vertebrae. By arranging the eight individually adjustable padding
elements in the seat pockets adjustments in
the lordotic area (lower lumbar spine) are
possible.
The OrthoFlex-seat is also a practical base
platform for therapeutic changes by an
orthopaedic technician who can install
custom seat support pads in the pockets.
The adjustment of the seat mesh and the
proper seat angle is crucial for a comfortable feeling while riding your recumbent.
The Gekko fxs has a retention belt system
with customizable straps on the seat. The
adjustable retention belt system can be
used, depending on the therapeutic need, as
lap belt or as 4- or 5-point-belt.

Adjusting the seat mesh
Eight tension belts on the back side of the
seat allow the adjustment oft the seat net
to your needs.
Does the seat feel to soft or gives you the
feeling of sitting on the seat frame, increase
the tension of the belts on the back side of
the seat.
Attention! Always tightly close
the seatback quick release lever. The seat is
a structural part of the tricycle frame. An
opened quick release may lead to frame
damage. Please pay attention to the instruc-
tions about quick release levers on page 7.
Is it hard or uncomfortable, or do you feel
like slipping off when going through curves,
release the belts in the relating area.
It may be necessary to put a high force on
the belts to apply sufcient tension to the
belts. If it can not be done by hand, make
use of a at nose pliers and pull the lose
end of the belts rmly. To easily loosen the
belt, pull up the round end of the strap
retainer.
Adjusting the seat back angle
A great advantage of the OrthoFlex mesh
seat on your Gekko fxs is the possibility
to adjust the seat back angle very quickly.
Thus rides in an upright seat position or in
a at position are possible according to the
individual needs.
The seat back is fastened with a quick
release lever on a slotted aluminium seat
mounting. You can adjust the seat back angle
by 16 degrees by simply opening the quick
release lever. Having set up your desired
seat back angle close the quick release tightly to make sure the seat back will not move
during the ride.
Padding with seat cushion elements
The sides of the seat are equipped with
special pockets – their openings are clearly
marked by blue ribbons. Open the hookand-loop straps of the mesh seat there.
The pockets for the padding are closed with hook-andloop straps.
Now, you can arrange the eight individually
adjustable padding elements in the pockets
according to the rider‘s needs.
You can slightly reduce the tension of the
seat seat net to get more play for inserting
the padding elements.

Adjusting the front boom
In order to adjust the leg length you have to
move the front boom (the front part of the
frame where the cranks are mounted) in
the main frame.
Loosing the bolts to adjust the front boom
Unscrew the bolts M8 x 35 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.
Adjust the front boom in a way that your
leg is fully extended when your heel (wea-
ring at 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
bicycle.
While you are pedalling, the ball of your
foot should be positioned above the centre
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
difcult to overcome this dead point, pedalling 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.
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. This can
result in serious accidents.
Attention! After you have unscrewed the clamping bolts take them off and
examine them for deformation. Lubricate
threads and heads thoroughly. Then re-t
the bolts. If they don‘t turn easily you will
have to replace the bolts.
HP
Velotechnik

Page 25
Adjusting to your size
Adjust the front boom so that your knee will not be fully
straightened when paddling.
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 cycle of the
frame’s cross bar, depending on the rider’s
shoe size. Please check before riding your
tricycle that there is enough heel clearance
(depending on insertion depth of the front
boom and your shoe size). If you colide, you
have to choose a shorter crank. There are
cranks in following lengths: 115 mm, 135 mm
and 155 mm.
Look beyond the bottom bracket shell
at the rear wheel axle and align the front
boom parallel to it. Then sit down on your
tricycle and check the position.
Attention! 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.
Tighten the bolts with a torque wrench
(tightening torque 14 – 16 Nm). On your
rst ride check whether there is sufcient
clamping. There might be the danger otherwise, that a single bolt overloads and the
frame gets damaged.
Handling instructions
HP
Velotechnik
23
Page 26
Adjusting to your size
Danger! If the bolts are tightened
too much or bent, the screw or the frame
can break! If the clamping is insufcient the
front boom can turn during a ride which
may cause your feet to slip from the pedals
and lead to injuries.
The plastic bush between front boom and main frame
must be visible at all time.
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 rst 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.
After moving the bottom bracket tube your
dealer has to adjust the chain length. By default your recumbent tricycle 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 shortened so that the derailleur cage is not fully
turned forward while shifting on the largest
chain ring in front and the smallest sprocket
behind. In order to choose the right chain
length, please consult the manual of the
derailleur manufacturer.
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.
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.

Adjusting to your size
We recommend to slightly readjusting the
front boom every 3 months in order to
provide a slightly different position to your
muscles and ankles. You might also nd a
more comfortable and more efcient riding
position.
A wrong adjustment may lead to pain in
your knees and inefcient pedalling. In
addition we recommend riding 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 nd more information about
this in the chapter „Slowly increase the
strain“ on page 14.
Check that there is at least a 5 cm (2") clearance between the end of the chain tube and other parts of the
drive train.
Attention! 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 front boom quick adjust is additional
equipment for HP
that feature a telescopic front boom for leg
length adjustment. It replaces the standard
bolts of the front boom clamping by quick
release levers. Two pulleys provide chain
length compensation while moving the front
boom.
The front boom must be clean and free
from wax or tenacious remains of chain
lube to make sure it can be easily slid in and
out.
Velotechnik recumbents
Handling instructions
The chain tubes must be prevented from
moving by a rubber tube over the retention
spring.
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.
First, shift the chain to the largest chain ring
and the largest sprocket to check the correct chain length.
Open both quick release levers. Slide the

when looking from the front. Close both
quick release levers. Please pay attention to
the instructions about quick release levers

Special pedals
With the rm connection between shoe
and pedal you do not need any power to
keep the foot on the pedal. Thereby a more
relaxed and round pedaling movement is
possible in which you even can pull the
pedals a little with your feet.
Without pedal binding, your feet might suddenly slip off the pedals, which can lead to
a fall. Therefore, modern pedal system with
binding contribute to safe riding. However,
using these pedals have to be practiced rst,
so that you can get out from the pedals
quickly in dangerous situations. Please read
the manual of the pedal manufacturer and
let yourself explain the usage of the pedals
from your bicycle dealer. Adjust the release
force of the binding to a low value to make
sure to get out of it securely.
Use only the supplied cleats of the binding
system manufacturer, no third-part products. Using unapproved cleats, the binding
system might noth operate safely.

Adjusting the handlebars
A good setting for the handlebars
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 sufciently 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.
Attention! When getting on and
off the tricycle, make sure to avoid pulling
at the handle bars or stepping on the tie
rods. To get off the tricycle, 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
rmly at the handlebars, the steering
mechanism can be damaged.
Setting the width and angle
The grip position can be tted to your body
and arm length by adjusting the handlebar.

2
The handlebar allows adjustment in width (1) and
angle (2)
Most riders are comfortable with an 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.
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.
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").

Adjusting the handlebars
The handlebar angle is individually adjustable.
Danger! Do not exceed the
handlebar width beyond the „Max“-mark,
otherwise a safe clamping is not possible
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 5 – 6 Nm. Check the
correct clamping of the handlebars by sitting
down on your tricycle and pulling the handlebars. The handlebars must not turn in the
stem.
Your bike shop can supply a special tting
lubricant that increases friction between
handlebar and stem.
Danger! Please take care that the
clamping area of the stem is thoroughly
trimmed and there are no sharp edges
which may cause handlebar failure.

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
shorten the cables or replace them by
longer ones.
Attention! After having adjusted
the handlebar 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 tricycle.
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 rmly to the handlebar.

Lighting system
Lighting systems for bicycles
If you want to ride your tricycle on public
streets, it must be equipped with a legal
lighting 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. Make sure to have enough energy
reserve if you use batteries.
For the bicycles, HP
dynamo lighting system with a tire dynamo
or a hub dynamo. The lighting system for
pedelecs is powered by the propulsion
system’s accumulator.
All 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 lighting 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 lighting system before every
ride.
Tire dynamo
Velotechnik offers a
moves towards the rear wheel. To turn the
light off, swivel the dynamo back to its initial
position by hand.
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 lighting system on or off stop riding, get
up from your tricycle 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.

Brakes
Handling of the brakes
Your tricycle is equipped with a powerful
high-quality braking system. Please read the
separate manual of the brake manufacturer
that comes with your tricycle 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.
Danger! Make sure to brake evenly using both hands. Braking unevenly or
only one side could inuence the steering
of your tricycle. Maximum braking performance is only achieved when braking
with both hands.
If your tricycle 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 tricycle can immediately
spin around and slide to the side. Remember which lever pulls the front brake and
which the rear brake.
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 tricycle and brake again.
If you are not familiar with the brakes we
recommend you to train at rst at low
speed and with little braking effect until
you nd the correct dose for an emergency
stop. Practice on a quiet road away from
trafc.
Try to avoid braking in bends, though if
necessary, touch the brakes carefully! 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, your tricycle can be equipped
with a coupled braking system with one
brake lever operating both front brakes.
For optimum handling some 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 tricycle may tumble over.
If you should hear any unusual sounds while
braking the brake pads might be worn out.
Do not use your tricycle any further until
you have checked the brake pads according
to the manual of the brake manufacturer or
before having you tricycle checked by your
local specialist dealer.

Brakes
Danger! Please note that the
braking distance is much longer when it is
wet or when the tricycle is heavily loaded.
When riding on wet, sandy, icy or slippery
roads you have to use the front brake very
carefully to avoid that your front wheels
slip. If they do so you will no longer be
able to control your tricycle, which might
lead to a serious crash
Danger! Always make sure that
the disc or rims 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. Riding with
contaminated braking systems can result in
serious accidents!
Danger! Never touch neither the
brake disc nor the brake caliper after long
braking as this may cause serious injury
(risk of burns).
Attention! Disc brakes can overheaton 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.
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 (20 mph), which should be done in
a safe area without trafc.
Parking brake
Always secure your tricycle 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 tricycle can be equipped
with a parking brake that is operated with a
thumb-shifter 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.

Brakes
Maintenance of the brakes
Attention! Always read the brakes
manufacturers manuals carefully before
doing any maintenance or repair jobs on the
brakes! Here you can nd detailed information and pictures of how to do it!
The brake pads suffer from wear due to
friction and have to be exchanged then.
Depending on riding conditions, they can
last between a few hundred up to several
thousand kilometres. Please read the manual
of the brake manufacturer carefully.
Check before every ride:
• that the braking system does not have any
damages or leaks by activating the lever,
holding it and checking the hose connec-
tions for possible leaks.
• that the brake lever pressure is ok by
pulling the lever and ensuring that full
braking performance is achieved before
the lever touches the handlebar. If this is
not the case, adjust the cable or change
the brake pads, for hydraulic disc brakes
pull the lever several times (pump) until it
feels rm.
• check the hydraulic braking system for the
correct pressure by pulling the lever, hol-
ding the pressure and checking the hose
connections, bleeding screw and compen-
sating tank for possible leaks.
Cable operated (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.
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.
Attention! Damaged cables with
single wires sticking out have to be replaced
immediately. Otherwise your braking system
may fail. Please take care that the cable ends
are always protected with a cap. Always
keep the cables shortly 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 qualied bicycle
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 qualied bicycle mechanic.
Hydraulic brakes
Hydraulic brakes on HP
tricycles use low viscosity mineral oil that,
contrary to DOT brake uid 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
tricycle.
Danger! All maintenance work on
the hydraulic system of your brakes may
only be carried out by a qualied 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.
Velotechnik
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 xing the hose to
the track rod must be tightened properly
to prevent it from moving.
In case of a damaged hose or any leakage of
oil always consult a qualied technician in a
bike shop.
Hydraulic disc brakes
Hydraulic disc brakes 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
(0.04"), of the brake disc it is 1,7 mm (0.07").
For further and more detailed information
on your disc brake model please refer to
the brake manufacturer’s manual.

Page 51
Brakes
Danger! If the brake pads or the
brake disc are worn out (pads: thickness
less than 2,5 mm (0.1") including metal back,
disc: thickness less than 1,7 mm (0.07")) the
pads may be torn out of the caliper while
braking. This leads to total loss of brake
power.
Attention! 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
tricycle 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.
Attention! 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.

Gear system and chain
Handling of the gear system
With the gear system you can adjust the
pedalling frequency, i.e. the number of
revolutions of the crank per minute, to the
terrain and the desired speed.
Your pedalling frequency should stay bet-
ween 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 recumbent tricycle comes standard
with a derailleur gear or with an 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 grip
shifters 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 pedalling.
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.
Attention! Under no circumstances allow the tricycle to roll back while
changing the rear gears, or try to pull the
tricycle backwards when the gear shifter
lever has been moved, as this will damage
the rear derailleur.
You should only change the gears while you
keep pedalling, smoothly and without applying great force, all the time that the chain
is moving between the sprockets. Using a
gear hub, you can change gears while pedalling and while standing.
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“).
Danger! Practice shifting gears
on a trafc-free street. In the course of this
make yourself familiar with the functioning
of the bar end shifters. Doing this in trafc
could distract your attention from possible
dangers.

Velotechnik
Page 53
Gear system and chain
Adjusting the gear system
Your dealer will adjust your derailleur
gearing system carefully before handing over
the tricycle. But during the rst 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.
Attention! Please read the manual
of the gear system manufacturer carefully
before working on the gear system.
Adjusting the gear indexing for the rear
derailleur
If the chain does not climb onto the next
sprocket, 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 tricycle.
When the chain climbs up easily, you need
to check that it still goes down easily onto
the smallest sprocket. If necessary turn the
adjuster barrel a little more and then try
shifting gears again.
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 tricycle is often parked
outside in bad weather conditions.
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 a professional bicycle mechanic.
Danger! If the tricycle 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.
Handling instructions
Attention! 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 tting
caps.

Gear system and chain
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 recumbent tricycle is approximately
2.5 times longer than a standard bicycle
chain (approximately 3.8 m (12'5")). But it
also lasts longer since a chain only wears
while bending at the sprockets and the
chain rings.
Use good chain oil that won‘t leave a sticky
lm 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
Lubetype lubricant. This lubricant is purely
based on PTFE (Teon) that keeps the chain
clean and dry. This way dirt simply falls off
and the tubes always stay clean.
Velotechnik recommends a Dry-
teed. 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.
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.
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 superuous 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 difcult for
the moisture in the tubes to evaporate
which may lead to corrosion at the chain.
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.
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 sufcient lubrication is not guaran-

Replacing the chain
The chain is one of the parts of the tricycle
that will wear out. This shows in a stretching
of the chain. Worn out chains do not t 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 chain ring. The chain may come off
to a maximum of 5 mm (0.2"). For a more
precise reading you can buy a chain measurement gauge in your bicycle shop.
Only use chains that are suitable for the
gear system of your tricycle. 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 t a worn sprocket or chain ring. We
recommend rust resistant Rustbuster-chains

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.
Danger! 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.
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. In order to perform any
work at the chain tubes you‘ll have to open
the chain and nally close it again. Please see
the instructions on „Chain“ on page 52.
The distance of the upper chain tube to the
chain wheel can be adjusted by sliding the
tube in the retention spring. It must be secured with the rubber tube over the spring.
Danger! 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 drive train the drive train can be blocked and the chain tubes may be destroyed.
Danger! 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!
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 (0.2 – 0.4") 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

expanded end immediately with cold water.
Take care that the tubes don‘t catch re.
At any rate work in a place with sufcient
ventilation.
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.
Replacing 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 protection 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
the bolt with 17 – 19 Nm. The recessed side
of the chain roller has to face to the frame.
loctite and tighten
Make sure the washer is placed between
chain roller and plastic tube / frame.
The front upper chain tube can be adjusted
in length at the retention spring . Push the
tube in the support to the desired position.
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.
Chain roller
The chain roller guides the chain below the
seat to the rear wheel and is an essential
part of the HP
It ensures that the suspension is not inuenced by pedalling.
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.

your local specialist dealer in case this
hook is missing.
Chain roller and chain tubes on Gekko fxs
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.
Dismounting and mounting of the chain
roller
To dismount the chain roller, the chain
tubes need to be removed. See also hints on
replacing the chain tubes (page 55).
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.
Attention! 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.
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.

Disassembling the wheels
Front wheels
To remove a front wheel, loosen the bolt in
the locking part at the inside of the knuckle
at least 6 mm (0.24"). 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.
Disassembling front wheels: Loosen the screw in the
locking part and then take out the front wheel out of
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.
Rear wheel
According to the conguration the rear
wheel is mounted with a quick release or
with nuts. Open the quick release or loosen
the nut with a 15 mm (0.6") wrench to
disassemble the rear wheel.
Make sure to properly close the quick
release lever or tighten the nut with 40 Nm
after reassembling the rear wheel.
Danger! Rear wheels can be
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.
Please pay attention to the instructions
about quick release levers on page 7.
Tyres
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 nd 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.
Handling instructions
The tubes come with Presta valves (also
called french valves). They are very airtight
and easy to pump up.
To do so, rst 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 oor 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.

Wheels
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.
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.
After you have exchanged the tires please
check if the wheels turn freely and check
the minimum distance between mudguards
and frame.
sible at your bicycle depends on the size of
your rims. Please ask your local dealer.
Spokes
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.
Attention! To true up the wheels
you need special skills, please have this work
done by an experienced bicycle mechanic.
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!
Front wheels
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 ETRTO size 406 (20").

headsets.
The headsets must be adjusted in order
to let the knuckles with the front wheels
attached turn easily without showing play.
To check the bearing play, pull the front
brake and grab the upper bearing cup with
your other hand. Now move your tricycle
back and forth. If the bearing has play the
upper cup moves noticeably in contrast to
the xed part. In this case loosen the clamping screw of the clamp above the upper

bit more. Afterwards, fasten the clamp again.
by turning it counter clockwise. Fasten the
clamp again afterwards.
The headset of tricycles is fastened a little
tighter as the headset of bicycles. A headset
that is too tight, leads to wearout and destroys the bearing.
Attention! The hex-headed screw
in the cap only adjusts the play of the head
set bearing. This screw will not safely hold
the knuckle in the frame. Take care that the
clamp is tightened as prescribed after you
have nished your adjustment. Please pay
attention to the table of fastening torques
on page 74.

) is called toe-out. The measu-
h
v
res 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 b
and bhbetween 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.
The distance between the front edges b

must be 0 – 2 mm (1/16") smaller than the
distance between the rear edges b
.
h
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 tricycle. Measuring at varying heights results in measuring errors.
Adjusting toe setting
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 thread locker. 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

Mudguards
Mudguards are exposed to very strong
vibrations, especially 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.
Front mudguards
Attention! You must not mount
additional parts like rear lights or reectors
to the mudguards since those may break
then. Retrot mudguards are aligned at
HP
Velotechnik before they are sent out.
After assembling them to the tricycle a nal
alignment must be performed.
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.
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.
Mounting of front mudguards
The front mudguard mounting is attached
by headset’s cap and screw and fastened
against the headset clamp. Make sure this
clamp is fastened properly, see page 63.

Companion bar
If the rider needs extra guidance, HP
technik can install its unique companion bar.
It allows an escort to actively control the
trike‘s steering and brakes as well as to give
the rider a little extra push. As the escort
walks on the left side next to the rider,
communication between the two is always
possible.
As well as the basic vehicle Gekko fxs, the
solid companion bar can be adjusted individually to driver and escort. It is adjustable
both in height and in alignment and thereby
adapts to the seat position of the driver as
well as to the body dimensions of the companion. A reliable function without affecting
the position of the driver is ensured. Of
course, the companion bar can be removed
without tools for transporting the vehicle.
The safety-related connection of the braking system of the Gekko fxs remains – a
detailed readjustment thus is omitted.

Adjustment of the companion bar
The companion bar can be adjusted in
height and angle. Open the middle clamp of
the telescopic height adjustment and move
the handle tube to the intended position.
The minimum insertion depth is 5 cm (2").
Danger! There is „max“-mark on
the handle tube. Do not pull the companion
bar out beyond this mark. Otherwise a safe
clamping is not guaranteed.
When adjusting the companion bar, make
sure that the handle tube is oriented
approximately horizontally and it does not
collide with the rider when steering. Check
it before every ride. The tightening torque
of the middle and lower clamp is 7 – 9 Nm.
Attention! The companion bar is
intended to give the rider a little extra push
and help steering. It is not tted for strong
braking by pulling the handle tube. To brake
the vehicle, the mounted braking lever must
be pulled. The maximum force on the handle
tube is 300 N (30 kg). Overloading can lead
to deformation or breakage of the companion bar.
The solid companion bar on the Gekko fxs enables
ermöglicht co-steering, accelerating and active braking.

Cleaning, conservation and
disinfection
The frame of the Gekko fxs has a high
quality and environmentally friendly powder
coating. The surfaces of the aluminium parts
are either polished or anodised. Threads and
technical contact areas can be unnished
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
inuences such as air pollution, dirt on the
roads and especially grit affects the parts,
and not only may this cause aws but also
serious structural damage of the parts by
corrosion.
In contrast to a widespread belief particularly the „non-rusting“ aluminium 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!
The best things to clean your bicycle with
are warm water and a soft cloth. If your
bicycle is very dirty rst 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.
Attention! 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.
Attention! Do not use any highpressure 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.
Attention! 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.
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 tricycle, 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 ows into
tiny gaps and pores. After some minutes the
solvent evaporates and leaves a dull and glu-
tinous lm. 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 52.
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-ityourself-store. That way you avoid scratches
in the powder coating and coating coming
off.
All fabrics are washable at 30° C. You can
disinfect the contact points like grips or the
seat with usual disinfectants. Make sure to
use cleaning agents that do not affect plastic.
Attention! Take care that after
folding the tricycle there are no parts rubbing against the frame. This may damage the
paintwork.

Maintenance routine
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 at 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.
Arrangements for further use
If the Gekko fxs has been used in accordance with regulations, got cleaned according to the cleaning tips and controlled by
your bicycle dealer, the bike is suitable for
further use.
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 parts that could come
loose during transport (seat cushion, water
bottles, luggage bags, pumps, pennants, etc.).
