is pushed backwards. When you press the on/off button on
the activated display the electrical drive unit could switch on.
Remove the battery from the e-bike before you begin work
(e.g. inspection, repair, assembly, maintenance, work on the
chain, etc.) on the e-bike, transport it by car or plane, or store
it. Unintentional activation of the electrical drive unit poses a
risk of injury.

battery contacts and corresponding holder contacts. Clean
them carefully with a soft, damp cloth.

it will improve the lighting performance.
● All components including the electrical drive unit may not be
immersed in water or cleaned with a high-pressure cleaner.
● The foam box used on the Shorty model is made from a sturdy
foam material called EPP (Expanded Polypropylene). EPP
insulates very well and has good wear and tear resistance.
Regular bicycle maintenance or generic household cleaning
products will not affect the material. Don't use solvents.
● Never submerge the e-bike battery in water.

8.2.1 Speed sensor check

In order for the speed sensor to function:
● Clean your bike in shorter intervals when you cycle on roads
have been prepared with winter road salt. The road salt may
cause damage to parts of your bike.
Never submerge the battery in water or clean using a jet
of water. Danger of short-circuiting which may pose a fire
hazard.
The gear hub and grip shifter are sealed and well protected
from the external environment. However, never use water
under pressure (such as pressure washers or water jets)
when you clean these parts to prevent malfunctions due to
water penetration.
Never use aggressive cleaners on any of the parts of your
e-bike. This may cause permanent damage to the bike.

Maintenance

1. The clearance between the speed sensor 26 and its speed
sensor magnet 27 needs to be at least 5 mm, yet no more
than 17 mm after a turn of the wheel (see image 32).
See later in this paragraph for information on how to adjust
the clearance if necessary.
2. The speed sensor needs to be connected properly.
