Checking the Speed Sensor
(see figure D)
The speed sensor 11 and its spoke magnet 12
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 clearance between speed sensor 11
and spoke magnet 12 is too small or too large,
or if the speed sensor 11 is not properly con-
nected, the speed indication a will fail, and the
eBike drive will operate in emergency mode.
In this case, loosen the screw of the spoke mag-
net 12 and fasten 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. When the speed is still not being indicated
in the speed indication a after this, please refer
to an authorised bicycle dealer.
Operation
Initial Operation
Requirements
The drive of your eBike can only be activated
when the following requirements are met:
– A sufficiently charged battery is inserted (see
operating instructions of the battery).
– The drive HMI is properly inserted in the
holder (see "Inserting and Removing the
Drive HMI", page English–2).
– The drive HMI is properly connected (see
"Checking the Speed Sensor", page
English–3).
Switching the Drive On/Off
Insert the battery into the holder and switch it
on via the On/Off button (see operating instruc-
tions of the battery).
Note: When switching on the battery, the pedals
of the eBike may not be subject to load, as oth-
erwise the output capacity of the drive will be
limited.
If the battery was inadvertently switched on
with load applied to the pedals, then switch it
off and then on again without load.
Bosch eBike Systems
Switching on the battery also switches on the
display of the drive HMI. The drive HMI indicates
the charge condition of the battery as well as
the settings of the drive unit.
The drive is activated as soon as you step into
the pedals (except when in start-assistance
mode, see "Switching Start-assistance On/Off",
page English–4). The assistance level depends
on the settings of the drive HMI.
As soon as you stop pedaling when in normal op-
eration, or as soon as you have reached a speed
of 45 km/h, the assistance from the eBike drive
is switched off. The drive is automatically re-ac-
tivated as soon you start pedaling again and the
speed is below 45 km/h.
To switch off the drive, switch the battery off via
the On/Off button (see operating instructions of
the battery).
When no power output of the drive is requested
for approx. 10 minutes, (e.g., because the eBike
is parked), the battery automatically switches
off to save energy.
Indications and Settings of the Drive HMI
Note: Indications and settings on the drive HMI
are only possible when the eBike battery is
switched on. The drive HMI does not have an
own power supply.
Charge Condition of the Battery
Besides on the charge-control indicator on the
battery itself, the charge condition can also be
read from indicator g of the drive HMI.
On indicator g, each bar of the battery symbol is
equivalent to a capacity of approx. 20 %:
100 % to 80 % capacity
20 % to 5 % capacity; the battery
should be recharged.
Less than 5 % capacity; drive assistance
is no longer possible. The LEDs of the
charge-control indicator on the battery go out.
When the eBike lighting is powered via the bat-
tery (country-specific), the capacity upon first
indication of the empty battery symbol will be
sufficient for approx. 2 hours of lighting. When
the symbol begins to flash, the lighting will con-
tinue to operate only for a short period.
