Power Assist Devices
Repair, cleaning and maintenance
protocol is available on our website. For the
adjustment of many handbike components, you
can also visit a specialist bicycle store.
16.1 Cleaning 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 or power assist
device 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.
The pushbutton, the display and the battery may
only be wiped with a damp (not wet) cloth. The
drive wheel can be cleaned with a soft sponge or
brush.
16.2 Air pressure of the drive
wheel
Check the air pressure of the handbike or power
assist device and wheelchair tires. The air pressure
of the 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.
16.3 Clamping device
Regularly lubricate the latching slot, the pin, the
latching.flap‘s.sliding.hinge.holes.and.the.spiral.
spring.located.in.the.latching.flap.with.spray.oil.
16.4 Automatic catch
Regularly lubricate the thread, taper washer and
taper socket of the ball handle nuts with grease.
16.5 V-Brake
16.5.1 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
brake.shoe.touches.the.rim.first..When.the.front.
part just touches the rim, the rear part may still
have 0.5 mm clearance. A common cause of
brake squeal is poor brake shoe adjustment.
• With properly adjusted brakes, the brake shoes
should.be.centered.on.the.rim.flank..If.you.have.
mounted the brake shoes too low, they can slip
off.the.rim.flank.and.get.caught.in.the.spokes..
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.
