Checking the Speed Sensor
17 Speed sensor
18 Spoke magnet for the speed sensor
The speed sensor 17 and its spoke magnet 18 must be at-
tached in such a way 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 clearance between the speed sensor 17 and
the spoke magnet 18 is too small or too large, or if the
speed sensor 17 is not properly connected, the speed indi-
cator f will fail, and the eBike drive unit will operate in the
emergency mode.
In this case, loosen the screw for the spoke magnet 18 and
fasten the spoke magnet to the spoke in such a way that it
runs past the mark of the speed sensor at the correct clear-
ance. If the speed is still not being indicated on the speed
indicator f after this is done, please contact an authorized
Bosch eBike dealer.

Switching the eBike System On/Off
Options for switching on the eBike system:
– If the on-board computer is already switched on when
inserted into the holder, then the eBike system will be
switched on automatically.
– When the on-board computer and the eBike battery
pack are inserted, briefly press the On/Off button 5 of
the on-board computer once.
– When the on-board computer is inserted, press the
On/Off button on the battery pack.
Once it is switched on, the eBike system is in the "OFF"
mode. Select the desired assistance level and take off.
The drive is activated as soon as you put pressure on the
pedals. The assistance level depends upon the on-board
computer settings.
As soon as you stop pedaling when in normal operation, or
as soon as you have reached a speed of 20 mph, the assis-
tance from the eBike drive unit is switched off. The motor
assistance is automatically re-activated as soon you start
pedaling again and the speed is below 20 mph.
Options for switching off the eBike system:
– Press the On/Off button 5 of the on-board computer.
– Switch the eBike battery pack off by using its On/Off
button (see battery pack operating instructions.)
– 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.
Power Supply for External Devices via
USB Connection
With the USB connection, it is possible to operate and
charge most devices whose power supply is possible via a
USB port (e.g., various mobile phones).
A prerequisite for the charging is that the on-board computer
and a sufficiently charged battery pack are inserted in the
eBike.
Open the protective cap 8 of the USB port on the on-board
computer. Connect the USB connection of the external de-
vice to the USB port 7 on the on-board computer using the
USB charging cable Micro A – Micro B (available from your
Bosch eBike dealer).
Once the consumer has been disconnected, the USB con-
nection must be sealed again carefully with the protective
cap 8.
 A USB connection is not a waterproof plug-in connec-
tion. When riding in the rain, an external device must
not be connected and the USB connection must be
completely sealed with the protective cap 8.
