from being removed from the holder. To do so, remove the
holder

(4)

from the handlebars. Put the on-board computer

in the holder. Screw the locking screw

Operation

Prerequisites

The eBike system can only be activated when the following
requirements are met:
– A sufficiently charged battery is inserted (see battery op-

erating instructions).

– The on-board computer is properly inserted in the holder

(see "Fitting and removing the on-board computer
(see figure

)", page English – 1).

– The speed sensor is connected properly (see drive unit

operating instructions).

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 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 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 no power is drawn from the eBike drive for about
10 minutes (e.g. because the eBike is not moving) and no
button is pressed on the on-board computer or the operating
unit of the eBike, the eBike system, and therefore also the
battery, will switch off automatically 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.

Energy supply of the on-board computer

If the on-board computer is in the holder

(4)

, a sufficiently

charged battery is inserted in the eBike and the eBike sys-
tem is switched on, then the on-board computer is powered
by the battery of the eBike.
If the on-board computer is removed from the holder

(4)

the energy is supplied via an internal battery. If the internal
battery is weak when the on-board computer is switched on,

<Attach to bike>

will appear on the text indicator

(d)

for

3 s. The on-board computer will then turn off again.
To charge the internal battery, put the on-board computer
back in the holder

(4)

(when a battery is inserted in the

eBike). Switch the eBike battery on by its on/off button (see
battery operating instructions).
You can also charge the on-board computer via the USB
port. To do this, open the protective cap

(8)

. Connect the

USB port

(7)

of the on-board computer via a suitable USB

cable to a standard USB charger or the USB port of a com-
puter (5 V charging voltage, max. 500 mA charging current).

<USB connected>

will appear on the text indicator

(d)

the on-board computer.
