Switching the eBike system on/off
The following options are available for switching on the
eBike system:
– If the on-board computer is already switched on when you
insert it into the holder, the eBike system will be activated
automatically.
– Once the on-board computer and the eBike battery are
fitted, briefly press the on/off button on the on-board
computer.
– With the on-board computer inserted, push the on/off
button on the eBike battery (bicycle manufacturer-spe-
cific solutions are possible when 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, Switching the
push assistance on/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 km/h, the eBike
drive switches off the assistance. The drive is automatically
reactivated as soon you start pedalling again and the speed
is below 25 km/h.
The following options are available for switching off the
eBike system:
– Press the on/off button of the on-board computer.
– Switch off the eBike battery using its on/off button (bi-
cycle manufacturer-specific solutions are possible when
there is no access to the battery on/off button; see the bi-
cycle manufacturer operating instructions).
– Remove the on-board computer from its holder.
If the eBike is not moved for approx. 10 min and no button is
pressed on the on-board computer, the eBike system
switches off automatically in order to save energy.
eShift (optional)
eShift is the integration of electronic gear-shifting systems
into the eBike system. The eShift components are electric-
ally connected to the drive unit by the manufacturer. The
separate operating instructions describe how to operate the
electronic gear-shifting systems.
Setting the assistance level
You can set the level at which the eBike drive assists you
while pedalling on the on-board computer. The assistance
level can be changed at any time, even while cycling.
Note: In some models, the assistance level may be preset
and cannot be changed. There may also be fewer assistance
levels available than stated here.
The following assistance levels are available as a maximum:
– OFF: Motor assistance is switched off. The eBike can just
be moved by pedalling, as with a normal bicycle. The
push assistance cannot be activated at this assistance
level.
