Maintenance and Care
ATTENTION
Regularly check the tightness and seating of the nuts holding the rear
wheel hub and the bolt for the engine support for models with the
coaster brake. The nuts holding the rear wheel hub must be tightened
to 20 Nm (= VERY FIRMLY!). Compliance with this tightening torque is
essentially required for the proper function of the drive. It is strongly
recommended that the mounting nuts and bolt for the engine support
are checked and re-tightened immediately after the first 10 km of
receipt of the bike, since the screw connections must be allowed to
settle in the new bike.
Pay attention to the chain tension when using a model that is equipped with a drive system
with a coaster brake function – too little tension of the chain can negatively affect the
braking performance of the coaster brake.
We recommend checking by the dealer of the spoke tension of the wheels and all bolted
connections (including the motor screw connections) after the first 200 km. It should
also be noted that shorter maintenance intervals should be complied with for Pedelecs
than for regular bicycles because of higher loads. Your dealer will gladly provide you with
the relevant advice.
To maintain the lasting and good functionality of the drive system, all plug contacts of the
drive system should be reviewed every two to three months and, if necessary, cleaned with
a soft dry brush. It must be ensured that no dirt or moisture gets into the battery holder.
The electric motor is a brushless DC motor, which does not have to be serviced.
Cleaning
ATTENTION
Never use a pressure washer to clean the drive system. A strong
jet of water could damage the electrical components of the drive
system!
We recommend cleaning the bike with a soft sponge or a soft brush. To clean the battery
holding rail, use a damp cloth. Always work with a little water and keep water away from
the electrical contacts. After cleaning, check the connectors for moisture and let them dry if
necessary before re-starting the bike.
