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 Gekko fx with standard
parts from the series production of
HP VELOTECHNIK.
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.

Legal requirements
When you ride your trike on public roads it
must comply with national legislation and
guidelines.These will vary from country to
country.
In general, there are minimum standards for
brakes, reflectors 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 V
ELOTECHNIK
trike in traffic 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 find out
about your legal obligations.
As an addition, we recommend to mount a flag
on a pole for better visibility in traffic.
The safety equipment on your trike must be
checked before every ride and maintained in
proper condition.
General safety instructions
Intended use
Your Gekko fx 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 50.This
first service is the prerequisite for further use
of the tricycle and for your warranty claims.

Load capacity
The maximum load (rider + luggage) is 130 kg
(286 lbs).The maximum total weight (bicycle +
rider + luggage) is 150 kg (330 lbs).The lower
limit is valid.
With an attached trailer, the maximum total
weight must not be higher than 150 kg
(330 lbs)
Carrying luggage
Luggage transport is only allowed on the special racks designed by HP V
ELOTECHNIK .
Maximum permitted load on the rear rack is
25 kg (55 lbs).
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.
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. Be careful 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 or the derailleur.
The rear rack is designed for standard bike
panniers.They need to be removed before
folding the Gekko fx.
Take care that your luggage does not cover
the lighting system and the reflectors of your
tricycle and that they stay fully functional.

Transport with the car
The best way to transport your tricycle is inside the car.The Gekko fx is very space saving
when folded and has minimum space requirements inside a car. Due to the special folding
mechanism there are no parts which have to
be stored seperately.
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.).
Do not take kids with you
The Gekko fx is not designed for the transport of children.You are not allowed to mount
a child's seat. It is only allowed to transport
children in a trailer that has been specially designed for that purpose.
Trailers
You are allowed to use trailers (double trail
only) up to 40 kg (88 lbs) with the Gekko fx.
You can mount a common trailer coupling on
the frame’s left dropout. HP V
ELOTECHNIK rec-
ommends using a coupling by W
EBER.
Always check the proper function of trailer
and towing trike after mounting a trailer.
For C
HARIOT trailers you can purchase a
special lowered towing bar from dealer
Z
WEIPLUSZWEI for bikes and trikes with 20”
rear wheel.
Added parts and accessories
Additional accessories may impair the function
of your Gekko fx.We advise you to generally
contact your dealer before mounting any special parts or accessories to your tricycle.
Take care that the handlebar and the folding
mechanism always stay moveable.You must not
add any parts to the handlebar, the seat, or the
main tube 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 Gekko fx, 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 like fairings,
handlebar fittings, bottle holders, etc. may
impair your safety due to additional loading
or clips with sharp edges.

Replacement of parts
The replacement of parts relevant for safety
(especially brakes, lighting system, stem, handlebar, knuckles, drivetrain) should only be done
with original parts by a qualified 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!
No alteration of parts
If you wish to have your tricycle coded the
code can be added to the gusset under the
crosstube. However, HP VELOTECHNIK recom-
mends the use of code stickers.
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, and
wheels. Please follow the tightening torque
settings listed in the table on page 43.
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
General safety instructions
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!
Caution! You are not allowed to perform
any work on the parts of the tricycle, especially frame, knuckles, 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.
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 43 in
this manual.
Adjusting your new trike
7HP
Velotechnik
Before the first ride: adjusting your
new Gekko fx
Your position on the Gekko fx is essential for
your riding comfort, well-being and efficient
cycling.Therefore you should adjust the frame,
seat, and handlebar to your individual requirements.
In order to adapt the Gekko fx 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 part 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 from side to side.
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.
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
Sit down on your trike to find out the correct
front boom position.
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 bush (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 Gekko fx 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.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 19.
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 drive 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. 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 Gekko fx meshseat
Your Gekko fx is equipped with a meshseat
which needs not to be removed for folding the
trike. Using eight straps, the seat surface can
be adjusted individually to your back.The backrest angle is fully adjustable with a quick release.The 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 seat is bowed up in this area (lumbar support).
The adjustment of the seat mesh and the
proper seat angle is crucial for a comfortable
feeling while riding your recumbent.
Adjusting the seat mesh
By means of eight straps on the backside and
underside of the seat frame the tension of the
seat mesh can be adjusted according to your
needs.
If the seat feels too soft, you sink in too far at
one spot or you sit on the seat frame you’ll
have to tighten the straps in that area.
If there is some spot where the seat feels too
hard and uncomfortable or you don’t have
enough lateral support you’ll have to loosen
the straps in the respective area.
You can use gripping pliers to tighten the
straps in case the force you can apply with
your hand is not enough.To loosen a strap the
semicircular side of the plastic connector must
be lifted to release the strap out of the connector.
Adjusting the seat back angle
A great advantage of the mesh seat seat on
your Gekko fx 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 8 degrees by
simply opening the quick release lever. In the
medium seat position the angle is about 38°
from horizontal. 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.
Adjustment of the head rest
To relax the muscles in your neck on long
rides you can purchase a head / neckrest to
mount on the seatframe. Its height and inclination is adjustable at the clamp.Wearing a helmet the headrest pad should be positioned under the lower helmet edge next to your neck.
Adjust the inclination in a way that the headrest does just not touch your neck / head
while riding. It may be necessary to cut the
two tubes protruding the clamp on the underside to prevent them from touching your back.
Adjusting the seat position
Caution! Always tightly close the quick re-
lease at the seat back.The seat is a structural part of the trike frame. An opened quick
release may lead to frame damage.
Caution! Do not push or carry your trike
on the head rest, this may damage the head
rest or the seat!

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 is clamped in a stem under the
seat.The stem may rotate in the frame and
transmits the rotation to a sheetmetal under
the frame tube.There are track rods attached
to the sheetmetal which transmit the steering
movement to the wheels.
Most riders are comfortable with a 85° angle
so that the bent grips point upwards and
slightly forward.
In order to change the angle loosen the four
screws of the stem/handlebar clamping. Move
the handlebars until they are in your favourite
position.Tighten the clamping screws with
5–7
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.
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.
Adjusting the handlebars
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 angle is individually adjustable.
Handlebar width is adjusted at the stem clamp under the seat.
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.
Cover all contact areas where cables move
and touch the frame with frame protection
stickers available at your specialist dealer or
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.
Adjusting your new trike
13HP
Velotechnik
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.
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.
Caution! 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
trike.
Folding with D.F.F.-move
Thanks to the Dual-Flat-Fold (D.F.F.) technology, your Gekko fx folds from a comfortable
touring trike to a compact package within 10
seconds.Then it can be stored upright or

7. Rearrange the seatback to your desired position and close the quick release.
Caution! Always tightly close the quick release at the seat back.The seat is a structural part of the trike frame.An opened quick
release may lead to frame damage.
Danger! Make sure the folding hinge is
properly closed.The safety bolt must be
snapped in correctly and the quick release
fastened tightly.
Caution! Don’t rest the bike on the rear
rack. It may become deformed.
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.
Adjusting your new trike

Velotechnik
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
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 to mount a well
visible and reflecting flag to the tricycle
while using it in traffic. Please ask your dealer for more information.
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.
18
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.

Velotechnik
Protective clothing, Clipless Pedals
Use clipless pedals
The pedals of your Gekko fx can be upgraded
on demand with a binding system.As soon as
you are comfortable with riding your Gekko fx
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 support 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.
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 fix the frame together
and 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. (This is not applicable for
the folding hinge quick release.)
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 Gekko fx 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 further 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 very 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.
22
HP
Velotechnik
27
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.
● the hydraulic braking system for keeping
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
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 Gekko fx 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.
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.
Gear system
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
24
HP
Velotechnik
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 Gekko fx, HP V
ELOTECHNIK offers a dy-
namo light systems with a tire dynamo or a
hub dynamo.
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 lighting 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.
29
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.
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.

Maintenance and care
Your Gekko fx 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 46.
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.
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.
Maintenance and care, Brakes
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.
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 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.
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.

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 VELOTECHNIK 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 Gekko fx 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 incl.
metal back is 2,5 mm, of the brake disc it is 1,7
mm. Please also 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.
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.
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! 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).

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 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 trike is often parked outside
in bad weather conditions.
32
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.

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 Gekko fx 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.
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.
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.
Maintenance and care
29HP
Velotechnik
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.

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
chain ring.The chain may come off to a maximum of 5 mm. For a more precise reading you
can buy a chain measurement gauge in your
bike shop.
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
changing performance.
HP V
ELOTECHNIK 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.
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.

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.

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 28.
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 28.
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.
Chain tubes
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!

Take care that the tubes don't catch fire.At
any rate work in a place with sufficient 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.
Changing the tubes
In order to exchange the upper rear chain
tube 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.
For exchaning the upper forward chain tube
cut the zip tie that connects the chain tube
with the mounting strap.Align the velcro of
the new tube to the mounting strap and secure the tube with a new zip tie.
Changing the r
etention 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.
Take the retention spring off this plastic tube
and put on the new retention spring.Turn the
spring so that the retention spring runs under
the bolt to the tube and the wire lies 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 threadlocker and tighten
the bolt with 17-19 Nm.The recessed side of
the chain roller has to face to the frame.
Changing the lo
wer chain tube
The chain tube is connected to the mounting
plate by a rubber sleeve.Additionally it is routed through a mounting strap in front of the
folding hinge. For dismounting the chain tube,
first cut the zip tie at the mounting strap, thengrab 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.
Exchange the lower chain tube. Slide it through
the lower loop of the mounting strap. Hook it
to the mounting plate in reverse order to dismounting. Fix the tube to the mounting strap
with a new zip tie.
Chain roller

HP
Velotechnik
37
Chain roller
The chain roller guides the chain below the
seat to the rear wheel.
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 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 chain roller is not symetrically shaped; the
recessed side of the chain roller has to face to
the frame, the flat side outwards.
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 30.
The chain roller is mounted with a special high
strength screw of the German strength grade
12.9 and it should 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.

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.
The distance between the front edges bvmust
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
trike. Measuring at varying heights results in
measuring errors.

Put the rod end under the sheetmetal bracket
at the handlebar stem. Insert the bolt and
tighten the self-locking nut.
On the other side of the track rod the rod
end is mounted on the underside of the
knuckle.There is washer and a spacer between
steering lever and rod end.There is another
spacer between rod end and self-locking nut.
Adjusting toe-in
The front wheels are held by knuckles which
can turn at the ends of the main frame.The
knuckles 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. 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.Attach the tie-rod to the handlebar stem and measure the toe-in as described
above. Repeat the adjustment process until
you reach the required toe-in setting.
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.
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 locknut.The lock nut
must be screwed tight to the track rod,
otherwise the rod end can loosen up or develop play.
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.

Danger! Secure the thread of the bolt with
threadlocker. Check all connections of the
steering system before every ride. If a connection loosens, the trike becomes unsteerable which may lad to serious injury.
The inside rod end is mounted under the sheetmetal of the stem,
the button-head is facing downwards.
The outside rod end is mounted under the knuckle. It is protected by a rubber sleeve from dirt and moisture. On top of and below the rod end there is a spacer bushing mounted.

If your bike is not equipped with mudguards,
there will be a spacer (5 mm) between cap
and clamp.When mudguards are installed, the
spacer is replaced by the mudguard mounting.
After adjustment of the head set bearing, align
the mudguards in a way that they won’t touch
the front wheel.
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.
Headset, Mudguards
Adjusting the head set play
The knuckles that connect the front wheels to
the frame are supported by A-Head-type 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 trike back and forth.
If the bearing has play the upper cup moves
noticeably in contrast to the fixed part. In this
case loosen the clamping screw of the clamp
above the upper bearing and tighten the screw
in the cap a bit more.Afterwards, fasten the
clamp again.
To check whether the front wheel turns
smoothly lift your bicycle at the frame so that
the front wheel moves freely above the
ground.When you hold the frame straight and
push the handlebars slightly they should move
smoothly from their middle position. If the
bearing is too tight, loosen the clamping screw
of the top clamp and loosen the hex-headed
screw in the end cap a little bit by turning it
counterclockwise. Fasten the clamp again afterwards.
Danger! 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 the clamp tightened
as prescribed after you have finished your
adjustment.
Caution! You must not mount additional
parts like rear lights or reflectors to the
mudguards since those may break then.
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.
Mounting m
udguards
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
The little screw in the mudguard mounting fits
in the clamping slot of the headset clamp and
secures the mounting against turning.
If you decide to uninstall the mudguards, replace the mudguard mounting with a 5 mm
spacer.
Maintenance and care
HP
Velotechnik
37
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.
Water bottle cage
You can mount a water bottle cage with a special bracket behind the seat.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.
Raincover
To keep the meshseat dry when your tricycle
is parked in the rain there is a raincover available as accessory. It can be stowed in the bag
of your meshseat.
To make sure the raincover is safely fastened
all over the meshseat the most forward strap
has to be equipped with two plastic clamps
(supplied with the raincover).The raincover
must be hooked to the clamps.

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.
When you exchange tires please note the
maximum width limit of 50 mm (approximately. 2 ").You have to use tires of ISO size 406
(20") on all wheels.The tire width possible at
your bicycle depends on the size of your rims.
Please ask your local dealer.
After you have exchanged the tires please
check if the wheels turn freely and check the
minimum distance between mudguards and
frame.
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.
Wheels
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.

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.
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.
Cleaning and conservation
The frame of the Gekko fx has a high quality
and environmentally friendly powder coating.
The surfaces of the aluminum parts 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!
Wheels, Cleaning and conservation
Danger! Take care that your spokes are al-
ways 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!
Caution! To true up the wheels you need
special skills, please have this work done by
an experienced bicycle mechanic.
Loosen the bolt inside the locking part to remove the wheel from
the knuckle.

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
28.
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 parts 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.

If HP V
ELOTECHNIK refuses to count a repair as
warranty case we will only carry out a repair
with costs after having talked to the customer
or his representative, the respective dealer.
It is necessary for the purchaser to fill in the
enclosed warranty registration form to benefit
from the extended warranty. This filled in form
has to be sent to HP V
ELOTECHNIK within 4
weeks after the purchase.
The warranty is only valid when the warranty
pass at the end of this manual has been filled
in when you received your trike and when
every inspection listed has been done and
recorded by your bicycle mechanic within the
described time schedule.
In the event of any warranty the warranty pass
together with a copy of the proof of purchase
has to be sent to HP V
ELOTECHNIK through
your dealer.
This warranty does not have any influence on
the rights of the purchaser according to his
statutory rights.

Warranty Pass
With the HP VELOTECHNIK Warranty Pass you
can assure the safety and proper function of
your tricycle for many years.
Like any other vehicle your trike has to be
checked for safe operation before riding.Your
bicycle has to be maintained at regular intervals, at least once a year you will have to take
your trike to a qualified bicycle mechanic for a
thorough check.
The service plan on the next page shows you
our mandatory maintenance and service
works.
If you wish you can set an upper price limit for
the service with your bicycle mechanic. If the
necessary works exceed this limit you will be
informed in advance.
You can avoid seasonal waiting periods in
spring and summer when you have your annual
inspection done in the quiet months from
October to January. Many bike shops then
have special winter check offers.At any rate
do make an appointment. Clean your bicycle
prior to the inspection since then many of the
checks by sight can be done quickly and at low
cost.
Please have your specialist dealer record every
inspection and service work in the Warranty
Pass.This is a requirement for the validity of
our extended warranty that exceeds the legal
warranty.

The service intervals 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
or dirt it is necessary to have shorter maintenance intervals.
In order to measure your riding performance
we recommend to use a bicycle computer.
The regular service maintains the safe operation and the value of your bicycle. Not only
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 Gekko fx
one day.

I have received the bicycle in good condition, adjusted to my size and performed a test ride.
I have been informed about the correct use of
the recumbent, the components like derailleur
and especially steering and brakes as well as the
necessity of regular service and maintenance. I
will read the manuals prior to the first ride and
have all future users read them too. I am aware
that I need to send the warranty registration form
to HP Velotechnik within four weeks of the purchase to qualify for the extended warranty.
