the wheel, moves past the speed sensor with a clearance of
at least 2 mm, yet no more than 8 mm.
If any structural changes are made, the correct distance
between the magnet and the sensor must be complied with
(see figure A).
Note: Make sure you do not damage the sensor or the sensor
holder when fitting or removing the rear wheel.
When changing a wheel, make sure that the sensor cable is
routed so that it is not under tension and has no kinks.
The CenterLock magnet (5) can only be removed and rein-
serted up to five times.
Operation
Start-up
Requirements
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 on-board computer operating instructions).
– The speed sensor is correctly connected (see "Checking
the speed sensor (see figure A)", page English – 2).
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, Switching the
push assistance on/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 km/h, the eBike
drive switches off the assistance. The drive is automatically
reactivated as soon you start pedalling again and the speed
is below 25 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.
Bosch eBike Systems
If the eBike is not moved for approx. 10 min and no button is
pressed on the on-board computer, the eBike system
switches off automatically in order 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.
Setting the assistance level
You can set the level at which the eBike drive assists you
while pedalling on the on-board computer. The assistance
level can be changed at any time, even while cycling.
Note: In some models, the assistance level may be preset
and cannot be changed. There may also be fewer assistance
levels available than stated here.
The following assistance levels are available as a maximum:
– OFF: Motor assistance is switched off. The eBike can only
be moved by pedalling, as with a normal bicycle. The walk
assistance cannot be activated at this assistance level.
– ECO: Effective assistance with maximum efficiency, for
maximum range
– TOUR/TOUR+:
TOUR: Steady assistance, long range for touring
TOUR+: Dynamic assistance for natural, sporty cycling
(only in conjunction with eMTB)
– SPORT/eMTB:
SPORT: Powerful assistance, for mountain biking and
cycling in urban traffic
eMTB: Optimum assistance whatever the terrain, rapid
acceleration when starting from a standstill, improved dy-
namics and top performance (eMTB only available in
combination with the drive units BDU250P CX, BDU365,
BDU450 CX and BDU480 CX. A software update may be
required.)
– TURBO: Maximum assistance even at a high cadence, for
sporty cycling
The requested motor output appears on the display of the
on-board computer. The maximum motor output depends on
the selected assistance level.
