Switching the push assistance on/off
The push assistance aids you when pushing your
eBike. The speed of this function depends on the se-
lected gear and can reach a maximum of 3.7 mph.
The push assistance function must only be used
u
when pushing the eBike. There is a risk of injury if
the wheels of the eBike are not in contact with the
ground while using the push assistance.
To activate the push assistance, briefly press the
WALK button on your on-board computer. After acti-
vation, press the + button within 10 s and keep it
pressed. The eBike drive is switched on.
Note: The walk assistance cannot be activated with
the riding mode set to OFF.

The push assistance is switched off as soon as one of
the following occurs:
– You release the + button (12);
– the wheels of the eBike are locked (e.g. by applying
the brakes or hitting an obstacle);
– the speed exceeds 3.7 mph.
The push assistance function is subject to local regu-
lations; the way it works may therefore differ from the
description above. It can also be deactivated.
Do not activate push assistance function while
u
riding on the bike. Only use push assitance func-
tion when pushing the eBike.
Switching bicycle lights on/off
On the model in which the lighting is powered by the
eBike system, the front and rear lights can be
switched on and off at the same time via the on-board
computer using the bike lights button (3).
Before starting each journey, check that your bike
lights are working correctly.
If the lighting is switched on, the bike light indicator c
(see "Start page", page English – 17) lights up in the
status bar of the display.
Switching the bike lights on and off has no effect on
the backlighting of the display.
