Assembly
Inserting and removing the battery pack
For inserting and removing the eBike battery pack in/from the
eBike, please read and observe the battery pack operating in-
structions.
Checking the Speed Sensor (see figure A)
The speed sensor 2 and its spoke magnet 3 must be mounted
in such a manner that the spoke magnet, after a turn of the
wheel, moves past the speed sensor with a clearance of at
least 5 mm, yet no more than 17 mm.
Note: If the distance between speed sensor 2 and spoke mag-
net 3 is too small or too large, or if the speed sensor 2 is not
properly connected, the speed indication will fail, and the
eBike drive unit will operate in emergency mode.
In this case, loosen the screw of the spoke magnet 3 and fas-
ten the spoke magnet to the spoke in such a manner that it
runs past the mark of the speed sensor at the correct clear-
ance. If the speed is still not being indicated in the speed indi-
cation after this, please contact an authorised bicycle dealer.

The drive is activated as soon as you step on the pedals (ex-
cept when in the push aid feature, see "Switching the Push-
assistance mode On/Off", page English–3). The motor out-
put depends on the settings of the assistance level on the on-
board computer.
As soon as you stop pedaling when in normal operation, or as
soon as you have reached a speed of 25 km/h, the assistance
from the eBike drive is switched off. The drive is automatically
re-activated as soon you start pedaling again and the speed is
below 25 km/h.
Options for switching off the eBike system:
– Press the On/Off button of the on-board computer.
– Switch the eBike battery pack off by its On/Off button (see
– Remove the on-board computer out of its holder.
If the eBike is not moved and no button is pressed on the on-
board computer for 10 minutes, the eBike system will shut
down automatically in order to save energy.
eShift (optional)
eShift is the integration of automatic gear shifting systems in-
to the eBike system. The eShift components are electrically
connected to the drive unit by the manufacturer. The opera-
tion of automatic gear shifting systems is described in the op-
