Operation
Starting up the eBike system
Requirements
The eBike system can only be activated when the following
requirements are met:
– A sufficiently charged eBike battery is inserted (see oper-
ating instructions for the battery).
– The on-board computer is properly fitted to the holder
Switching the eBike system on/off
The following options are available for switching on the
eBike system:
– Slide the on-board computer onto the holder (4).
– Once the on-board computer and the eBike battery are
fitted, briefly press the On/Off button (5) on the on-board
computer.
– With the on-board computer fitted, press the On/Off but-
ton on the eBike battery (bicycle manufacturer-specific
solutions are possible whereby there is no access to the
battery On/Off button; see the battery operating instruc-
tions).
The drive is activated as soon as you start pedalling (except
if you are using the push-assistance function or if the assist-
ance level is set to OFF). The motor output depends on the
settings of the assistance level on the on-board computer.
As soon as you stop pedalling when in normal operation, or
as soon as you have reached a speed of 25/45 km/h, the
eBike drive switches off the assistance. The drive is automat-
ically reactivated as soon you start pedalling again and the
speed is below 25/45 km/h.
The following options are available for switching off the
eBike system:
– Press the On/Off button (5) on the on-board computer
for at least 1 second.
– Switch off the eBike battery using its On/Off button (bi-
cycle manufacturer-specific solutions are possible
whereby there is no access to the battery On/Off button;
see the bicycle manufacturer operating instructions).
– Remove the on-board computer from its holder.
If no power is drawn from the eBike drive for about
10 minutes (e.g. because the eBike is not moving) and no
