6.3.  AFTER AN ACCIDENT

If due to an accident, parts of the drive system are visibly damaged 
(cable, motor, battery), a hazard of electric shock exists.
-> Immediately remove the battery in such case. Check the drive sys-
tem by a qualified dealer.

Any damages caused to the carrying parts of your Pedelec due to an 
accident may lead to a breakage hazard.
-> After an accident, contact your specialist dealer to check all 
damaged parts such as frame, fork, handlebar, stem, saddle support, 
pedal crank and pedals, and exchange any parts if required. 

6.4.  BATTERY

The battery has a guaranteed service life of two years (warranty term) and 500 
charging cycles, with a remaining capacity of 60% after this period. A charg-
ing cycle means a complete charge of the battery with one single charge or 
several partial charges (e.g. two half charges). 
A battery is a wear part, as it ages over time or wear is accelerated rate by its 
use. The battery life depends on the following factors:

Stress

Battery life is reduced by a high demand on the motor output (strong stepping 
up, high supporting levels).
