Product Description & Intended Use
4 Product Description &
Intended Use
The handbike is coupled to a manual wheelchair as
a manual traction aid. This allows the driver to be
supported in his mobility. The aim is to extend the
range of action by making it easier to cover longer
distances independently. Coupling the handbike
creates a three-wheeled vehicle with three relatively
large wheels. The handbike therefore improves
driving characteristics on uneven surfaces.
Obstacles can also be overcome more easily.
Driving downhill and on slopes becomes safer due
to the additional braking systems. The handbike
can be independently coupled to and released
from the wheelchair by the rider. The wheelchair as
such is not changed and its properties remain fully
intact.
5 Safety and driving
instructions for accident
prevention
WARNING
These instructions are for your own safety.
Please read them carefully before operating the
hand bike and observe the instructions! Failure
to observe the operating instructions could result
in damage to the product as well as serious
personal injury. We accept no liability for damage
resulting from failure to observe the operating
instructions.
NOTE
Observe all safety and hazard information and
instructions, both in this and in all other operating
instructions supplied.
5.1 Safety instructions
For your own safety, do not go without a bicycle
helmet when riding a handcycle.
5.1.1 Permitted speed
Be sure to comply with the legal regulations of the
country in which you operate the handbike. The
hand bike is approved for a maximum speed of
25 km/h. On steep inclines, you may only ride at

manufacturer may limit this. Use the lower value as
a guide.
5.1.3 Users with small children
In the interest of the child, please refrain from
riding a handbike with a child on your lap. There is
a high risk of injury from the toothed belt or chain
and from the rotating cranks.
5.2 Safety checks
WARNING
Carry out the following safety checks before every
journey. These are primarily for your safety and
the safety of all other road users.
5.2.1 Air pressure
Check the air pressure of the handbike and
wheelchair tires. The air pressure of the handbike
tire should be about 3-4 bar, the air pressure of
the wheelchair drive wheels about 5-7 bar. For the
exact maximum values, please refer to the imprint
on the respective tire. Too low an air pressure of
the wheelchair wheels increases the risk of tipping
over, especially in curves!
5.2.2 Secure t of all components
Check all components, especially all screws, for

be checked particularly carefully and tightened if
necessary to exclude twisting. For the exact torque
values, please refer to “E Torque list”.
5.2.3 Straight run
Determine whether the drive wheel is aligned
centrally to the wheelchair. The wheel must be in
the center of the wheelchair track. Deviations of no
more than 1 cm from the center are permissible. If
necessary, use the instructions from “9 Coupling
the handbike to the wheelchair”.
The double-acting steering return supports
straight-ahead running. Detailed information or
setting instructions can be found in “11.1 Function
of the steering damper”.
WARNING
An incorrectly aligned drive wheel can lead to
accidents due to poor straight-ahead running and
vibrations.

distance.
Make sure that the parking brakes of your
wheelchair are set correctly. Always use the
parking brakes to secure your vehicle against
unintentional rolling away, especially when parking
on sloping surfaces. Avoid parking on sloping
surfaces if possible.
Ensure that the coaster brake detent button is fully
engaged. Also test the function of the automatic
back-pedal engagement (“12.1 Coaster brake”).
5.2.5 Toothed belt
Check the toothed belt for mechanical damage and
irregularities.
Check the tension of the toothed belt and adjust
the belt if necessary (“5.2.5 Toothed belt”).
5.3 Driving instructions
5.3.1 Getting used to the handbike
WARNING
Always adjust your driving to the degree of your
disability.
WARNING
Always drive only fast enough to be able to
brake safely at any time, even in unforeseeable
situations! This applies especially to downhill
driving.
WARNING
Always hold the cranks with both hands when
riding and braking to reduce the risk of accidents.
Safe control of the combination of wheelchair and
handbike requires some practice. Cautious and
slow riding is particularly useful for beginners.
Avoid mountainous terrain and bad roads at the
beginning until you have familiarized yourself with
the driving characteristics of the handbike.
By attaching the handbike to your wheelchair,
the four-wheeled wheelchair becomes a tricycle
with various advantages and disadvantages. In
curves, a tricycle is more unstable than a normal
wheelchair! In the beginning, familiarize yourself
with the new driving and tilting behavior by driving
carefully. Avoid jerky steering movements at all
costs!
Also slowly get used to the higher speeds that can
be reached with the handbike. Adjust your speed to

5.3.2 Driving at dusk and darkness
Always switch on the built-in lighting for rides at
dusk and in the dark. Attach the supplied rear light
to the back of your wheelchair. Always check the
batteries for the rear light before driving off and
have new ones ready.
5.3.3 Risk of falling
Avoid jerky steering movements at all costs!
Drive at a slow speed, especially in curves and in
unclear situations. Tilt your upper body towards the
inside of the curve (like a cyclist) to avoid tipping
over the wheelchair.
With narrow wheelchairs and little camber of the
wheelchair’s drive wheels, the lateral tipping hazard
is particularly high. To reduce the risk of tipping, we
recommend our track widening Kippex.
To avoid the risk of falling, do not perform the
following maneuvers with the handcycle:
• Driving over several steps or landings
• Driving over a curb at an angle
• Turning on sloping roads
• Quick steering movements
• Abrupt braking in curves
• Braking too hard on wet roads
Reduce your speed when transitioning between
slopes and level terrain.

negative camber of the wheelchair’s rear wheels.
5.3.4 Mountain rides
If the incline is too steep, the drive wheel can lose
grip and spin. To improve the climbing ability,
you can equip your handbike with a wheelbase
extension and additional weights. These also have
a positive effect on traction on unpaved paths and
braking behavior. Avoid attaching weight (e.g. a
backpack) to the back of the wheelchair. It is better
to use a luggage carrier at the front.

R&E Stricker Reha-Entwicklungen GmbHManual Handbikes
Condition of the wheelchair
WARNING
If the drive wheel slips when driving downhill, it
may be necessary to additionally apply the brakes
of the wheelchair.
6 Condition of the wheelchair
Your handbike can be mounted to different
wheelchairs. For this purpose, your wheelchair
should be in a technically perfect condition. Do not
use a wheelchair that has already undergone major
repairs to the frame. We recommend wheelchairs
with rigid frames, as these offer greater stability
for use with a handbike than folding wheelchairs.
Nevertheless, most folding wheelchairs are
suitable for combination with our handbikes. If you
have any questions about your wheelchair model or
a planned new purchase, please contact us.
Make sure that the brakes of the wheelchair are in
perfect condition.
Despite the attached handbike, you can move the
wheelchair normally by driving the rear wheels.
This means that driving forwards and backwards
is possible without restriction. Steering by moving
the wheelchair wheels is only possible to a limited
extent due to the automatic steering reset.

8.1 Unpacking the handbike
The handbike is tied up in the box for transport. Cut
the cord before removing the handbike.
For transport, both handles are removed and
both longitudinal tubes are twisted upwards. The
assembly and settings of the parts are explained
below.
NOTE
To perform all adjustments, place the handcycle
and your wheelchair securely on level, solid
ground. Make sure there is enough space and
light to carefully implement the adjustments.
8.2 Adjusting the inclination of
the headstock tube
WARNING
Make sure that the corner brackets secured by the
S1L and S1R screws do not slip out of the cross
tubes. Do not use the insertion depth of the corner
brackets to adjust the width of the clamping
device.
Loosen the S1L and S1R screws (Fig. 2) using the
Allen key (SW 6) provided. Turn the longitudinal
tubes to the desired angle to the control bearing

adjustment of the crank position, you may have to
adjust the angle again. Lightly tighten the S1L and
S1R bolts.
After completing all adjustments, tighten the S1L
and S1R screws to a torque of 30 Nm.
NOTE
If you make adjustments to the inclination of the
headset tube while the handbike is coupled to the
wheelchair, also loosen the S3L and S3R screws
to prevent tension in the frame. Tighten them
again afterwards with a torque of 30 Nm.
8.3 Mounting the handles and
cranks
If necessary, place the cranks back in place and
tighten the screws to a torque of 25 Nm. Make sure
that the cranks on a handbike are aligned in the
same way as on a bicycle.
Screw the two handles to the cranks and tighten
the screws (SW15) with a torque of 20-25 Nm.
8.4 Adjusting the length and
width of the clamping device
To adjust the length of the longitudinal tubes and
the angle of the clamps, loosen screws S3L and
S3R. Make sure that the length of the longitudinal
tubes is always set identically on both sides
(Fig. 3).
Adjust the angle of the clamps according to the
wheelchair frame at the clamping position. This is
especially important for wheelchairs with V-shaped
frames. Lightly tighten the S3L and S3R screws.
After completing all adjustments, tighten the S3L
and S3R screws to a torque of 30 Nm.
NOTE
If you make adjustments to the length of the
longitudinal tubes while the handbike is coupled
to the wheelchair, also loosen the S2L and S2R
bolts to avoid tension in the frame.
To adjust the width of the clamping device, loosen
the S2L and S2R screws. Adjust the clamping
device to the width of the wheelchair frame. Make
sure to set the same angle to the cross tube on
both sides (Fig. 3). Lightly tighten the S2L and S2R
screws. After completing all adjustments, tighten
the S2L and S2R screws to a torque of 30 Nm.

8.5 Coupling the handbike to the
wheelchair for the rst time
Make sure that the screws S1L and S1R as well as
S3L and S3R are only slightly tightened. A slight
adjustment according to the wheelchair should still
be possible. Make sure that the handbike stands
straight.
Align the wheel of the handbike exactly in the
center of the wheelchair track. A maximum
deviation of 1 cm from the center is permissible.
Use the footrest to check the alignment.
WARNING
An incorrectly aligned drive wheel can lead to
accidents due to poor straight-ahead running and
swinging tendencies.
To simplify the adjustment, you can make a
template (Fig. 4). Then drive the wheelchair up
to the template so that the wheels are the same
distance from the line of symmetry. Place the
drive wheel of the handbike exactly on the line of
symmetry.

WARNING
When lifting the front wheels into the driving
position, both locking pins must engage
simultaneously. This is absolutely necessary for
proper function.
The length of the latching slot provides a reference
point for the setting. When the handbike is parked,
about 1 cm of this should be visible. The longer the
visible part is in the parked position, the greater the
ground clearance in the driving position.
After adjustments have been completed, check the
ground clearance by lifting the front wheels of the
wheelchair into driving position. We recommend a
ground clearance of approx. 3-4 cm. Carry out the
previously described steps until the adjustment
meets your requirements. The adjustment of the
ground clearance may have an effect on the crank
position. Adjust this again if necessary.

Once you have carefully adjusted the handbike to
your wheelchair, you can easily and quickly connect
and disconnect it from your wheelchair at any time.
If locked, unlock the Automatic catch. To do this,

release the locking pin. Now you can adjust the
clamping device and thus relax the automatic
detents to maximum length. We recommend that
you close the detents again immediately to avoid
injury when operating the clamping levers.
Open the clamping device on both sides just
enough so that they can be slid over the front
frame tubes of the wheelchair. Open the clamps
only as far as necessary, as opening them too far
could cause the clamping nuts to fall out (after
approx. 20 turns).
WARNING
Tighten the ball handle nut or the tetrastar nut
with a maximum torque of 6-8 Nm!
Grasp the handbike by the handlebar and attach
it to the front frame of the wheelchair using the
clamping device. Now tighten the clamps on both
sides.
For your own safety, we recommend locking the
brakes on the wheelchair and handbike for the
coupling process. This will prevent the handbike
or wheelchair from moving and you will have both
hands free to close the clamps.
To further simplify the coupling process, you
will receive positioning clamps together with the
handbike, which you can permanently mount on the
wheelchair. You can easily and safely position the
handbike’s clamping device on these and only have
to close the clamps.
NOTE
When closing the clamps, always make sure that
the clamps are aligned parallel to the tubes of
the front frame of the wheelchair. If this is not the
case, there is a risk of damage to the PVC caps.
Before coupling, make sure that the PVC caps
are undamaged. Damaged PVC caps can cause
damage to the wheelchair.
WARRANTY & LIABILITY NOTICE
The PVC caps are wearing parts, therefore no
warranty applies to them. We accept no liability
for damage caused by damaged PVC caps.
Now release the brakes of the handbike. Push the
handbike forward by the handlebar so that the front
wheels of the wheelchair lift off the ground. Push
the handbike forward until the automatic locks
engage on both sides. You should hear a distinct
click. Check whether both locking pins are visibly
engaged.

Steer
11 Steer
Steer the handbike by turning the steering bearing
tube (handbike stem) using the crank handles. The
steering is equipped with a double-acting steering
damper, which ensures optimum directional
stability. For your own safety, avoid rapid steering
movements, especially when riding fast. There is a
risk of tipping over with the vehicle.
11.1Function of the steering
damper
The steering damper is located at the upper end
of the fork. Via the device, the steering is damped,
straight-line stability is supported and automatic
steering return is achieved. These functions are
provided by several steering damper rubbers.
There is a key milled hole (SW 13) on the lower
bolt of the tensioning rubbers. Turn this to the right
or left to adjust the fork and thus the straight run
(Fig. 8). If necessary, also open the nut on the front
of the fork.

12 Breaks
SAFETY INFORMATION
The brakes are designed for a single-seat
handbike. Use on other vehicles or equipment
will void the warranty. Improper use may result in
serious personal injury.
For safety reasons, all models are equipped with
two independent brakes or a brake with two
independent operating mechanisms.
Before each ride, check the function of the brakes
and the brake pads for wear.
12.1Coaster brake
EQUIPMENT NOTE
All handbikes in the City model series, with the
exception of the City Max model, have the coaster
brake installed as standard. All other model series
offer the coaster brake only as an optional extra.
You can switch off the coaster brake for
maneuvering. Turn the detent lever 90 degrees
counterclockwise so that it remains in this position
(Fig. 9).
Fig. 9: Coaster brake
To switch on, turn the knob back to the starting
position. You can also activate the automatic
switch-on by turning the cranks forward.
NOTE
Before each ride, make sure that the detent button
is fully engaged, test the function of the automatic
backpedal switch and check the function of the
brake and the wear of the brake pads.
If the coaster brake is applied very strongly by
the cranks, the coaster may lock up, especially
in the three fastest gears. This will cause you to

process may only become effective if you move the
cranks as load-free as possible for a moment.
13.2Derailleur
Only shift the derailleur while riding. Do not shift
the derailleur when stationary or when the cranks
are not moving. For the repositioning of the
chain by the shifting process, the rotation of the
chainring by cranking is absolutely necessary. This
can be done under load or with load-free cranking.
13.3Planetary gear Mountain-

15 Repair, cleaning and
maintenance
Maintain your handbike regularly. Your safety
depends greatly on the condition of the handcycle,
especially the condition of the brakes. The service
life of the handbike is considerably extended by
maintenance and care. For detailed instructions
of standard components use the offers of
the respective manufacturers on the Internet.
Professional maintenance can be performed by
us or your dealer. We recommend professional
maintenance every 2 years. A maintenance
protocol is available on our website. For the
adjustment of many handbike components, you
can also visit a specialist bicycle store.
15.1Cleaning and care
Clean your handbike with warm fresh water and
a sponge. For stubborn dirt, we also recommend
Sonax® Bike Cleaner (Stricker item no. 873027-
0). If you use the handbike near the sea or at the
beach, clean the device regularly with plenty of
fresh water to avoid corrosion.
WARNING
Avoid cleaning the handbike with high water
pressure. There is a risk that water will penetrate
the control and operating unit. These could be
destroyed as a result.
After cleaning, spray the frame of the handbike
and the screws with care oil. This further prevents
corrosion. We recommend Sonax® SX 90 PLUS
multifunction oil or WD40.
WARNING
Do not spray the care oil on brakes or rims and do
not spray on rubber parts.
15.2Air pressure of the drive
wheel
Check the air pressure of the handbike and
wheelchair tires. The air pressure of the handbike
tire should be about 3-4 bar. For the exact
maximum values, please refer to the imprint on the
respective tire.
When riding on loose surfaces or inclines, we
recommend reducing the air pressure of the drive
wheel to about 2 bar. This increases the contact
area of the tire and improves the grip.
EQUIPMENT NOTE
If you regularly use your handbike in conditions
such as loose ground or inclines, it may be
advisable to use different tires. Please feel free to
contact us about this.

15.5V-Brake
15.5.1 Adjustments
Full braking performance can only be achieved with
correctly adjusted brakes. Therefore, pay attention
to the following points during adjustment:
• With properly adjusted brakes, the brake pads
should have a small distance (1.5-2.0 mm) to
the rim. The greater the distance, the lower the
braking effect and you need considerably more
force to brake.
• Align the brake shoe almost parallel to the rim.
When braking, the brake shoe should be in full
contact. Make sure that the front part of the

If the brake pads are mounted too high, the tire
can be damaged by the brake pads.
• Ensure the correct position of the brake arms to
achieve the best possible braking performance.
When the pads are in contact with the rim, the
brake arms should be vertical. Use the washers
of different thicknesses to achieve the correct
alignment.

same distance to the rim.
15.5.2 Maintenance
Be sure to check the brakes regularly. Only then
can you rely on the function of the brakes and
come to a safe stop even in dangerous situations.
Pay attention to the following points when
checking the brakes:
• Are the brake shoes in good condition?
• Carefully clean the brake shoe from time to
time with emery paper or a wire brush.
• Replace worn brake pads.
• Do the brake shoes have the correct alignment

you may have to try several measures to eliminate
the cause. The following measures can help to
eliminate the problem.
• Adjust the brake shoe slightly higher or lower to

Too tight radii lead to unnecessarily high hand
forces due to friction of the brake cable. Outer
sheaths that are laid too generously have the same
effect. Corroded brake cables also impair braking
performance and should be replaced.
15.5.5 Changing the brake pads
In the case of a brake shoe with replaceable brake
lining, pull the pin out of the brake shoe using a
pair of combination pliers. The brake lining can
now be pulled off. If necessary, use combination
pliers for this if the brake lining is very tight. If the
brake lining of the brake shoe cannot be replaced,
replace the entire brake shoe.
