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.
Notice:
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.
Operation
Initial Operation
Requirements
The eBike system can only be activated when the following
requirements are met:
– A sufficiently charged battery pack is inserted (see oper-
ating instructions for the battery pack).
– The display unit is properly inserted in the holder.
– The display unit is properly connected.
Switching the eBike System On/Off
Options for
switching on
the eBike system:
– If the display unit is already switched on when inserted
into the holder, then the eBike system will be switched
on automatically.
– When the display unit and the battery pack are inserted,
briefly press the On/Off button
5
of the display unit
once.
– When the display unit is inserted, press the On/Off but-
ton on the battery pack.
The motor assistance is activated as soon as you step on
the pedals (except when in the
“OFF”
assistance mode).
The motor assistance depends upon the settings of the dis-
play unit.
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 display unit.
– Switch the battery pack off by using its On/Off button
(see battery pack operating instructions.)
– Remove the display unit out of its holder.
If no power is drawn from the drive unit for about
10 minutes (e.g., because the eBike is not moving), the
eBike system will shut down automatically 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 display unit and a
sufficiently charged battery pack are inserted in the eBike.
Open the protective cap
8
for the USB port on the display
unit. Connect the USB port of the external device to the
USB socket
7
on the display unit using a standard-compli-
ant Micro A/Micro B USB 2.0 cable. Using a USB cable that
is not standard-compliant or a cable/adapter combination
can lead to damage to the display unit.
