Description
The bicycle does not have a separate emergency stop 
or emergency shut-off button. The drive system with 
removable display can be stopped in case of 
emergency by removing the display. 
The motor switches off automatically as soon as the 
rider no longer pedals, the temperature is outside the 
permitted range, there is an overload or the shut-off 
speed of 25  km/h has been reached.
A push assist system can be activated. The push 
assist continues to drive the bicycle as long as the 
rider pushes the plus button on the handlebars. The 
speed can be a maximum of 6  km/h in this case. The 
drive stops when the plus button is released.
3.5.1 Battery
The lithium ion battery has an internal electronic 
protection circuit. It is matched to the charger and the 
bicycle. The battery temperature is monitored at all 
times. The battery is safeguarded against deep 
discharge, overcharging, overheating and short 
circuit. In case of a risk the battery is switched off 
automatically by a protective circuit. If the electric 
drive system is not used for about 10  minutes (e.g. the 
bicycle is stationary) and no button has been pressed 
on the display or the control panel, the electric drive 
system and the battery are automatically switched off 
to save energy.
The service life of the battery can be extended if it is 
well cared for and, above all, stored at the correct 
temperatures. Even if the battery is cared for properly, 
the charge status of the battery reduces as it ages. If 
the operating time is severely shortened after 
charging, this is a sign that the battery is spent.
