Switching on/shutting down the on-board
computer
To switch on the on-board computer, briefly press the on/
off button (5). The on-board computer can also be switched
on when it is not inserted in the holder (if the internal battery
of the on-board computer is sufficiently charged).
To switch off the on-board computer, press the on/off but-
ton (5).
If the on-board computer is not inserted in the holder, it
automatically switches off after 1 minute to save energy if no
button is pressed.
If you are not going to be using your eBike for several
u
weeks, remove the on-board computer from its
holder. Store the on-board computer in a dry environ-
ment at room temperature. Regularly recharge the on-
board computer's internal battery (at least every three
months).
Battery charge indicator of the eBike battery
The battery charge indicator of the eBike battery (i) displays
the state of charge of the eBike battery, not that of the on-
board computer's internal battery. The eBike battery's state
of charge is also indicated by the LEDs on the eBike battery
itself.
In the indicator (i), each bar in the battery symbol repres-
ents approximately 20 % capacity:
The eBike battery is fully charged.
The eBike battery should be recharged.
The LEDs of the battery charge indicator on the
eBike battery go out. The capacity for assisting
the drive has been used up, and assistance is
gently switched off. The remaining capacity is
made available for the lighting and the on-
board computer. The indicator flashes. The ca-
pacity of the eBike battery is enough for about
two hours of lighting. This does not account for
other consumers (e.g. automatic gearbox, char-
ging external devices at the USB port).
If the on-board computer is removed from the holder (4),
the state of charge that was last displayed for the eBike bat-
tery is saved. If an eBike is powered by two eBike batteries,
the battery charge indicator for the eBike battery (i) will dis-
play the state of charge of both eBike batteries.
OFF
If an eBike has two eBike batteries inser-
ted into it and both eBike batteries are
MPH
KM/H
charged on the bike, the charging pro-
gress of both eBike batteries will be in-
dicated on the display (the left-hand
eBike battery pack is being charged in
the illustration). You can also tell by the
flashing indicator on the eBike battery
which of the two eBike batteries is being
charged.
Bosch eBike Systems
Setting the assistance level
On the operating unit (9), you can set how much the drive
assists you while pedalling. 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: Drive 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
To increase the assistance level, press the + button (12) on
the operating unit repeatedly until the required assistance
level appears on indicator (b). To decrease the assistance
level, press the – button (11).
The requested drive power appears on the display (a). The
maximum drive power depends on the selected assistance
level.
When the on-board computer is removed from the
holder (4), the assistance level that was last displayed is
saved; the drive power indicator (a) remains empty.
Interaction between the Drive Unit and Gear-
shifting
The gear shifting should be used with an eBike in the same
way as with a normal bicycle (observe the operating instruc-
tions of your eBike on this point).
Irrespective of the type of gear shifting, it is advisable that
you briefly reduce the pressure on the pedals when changing
gear. This will aid gear shifting and reduce wear on the
powertrain.
By selecting the correct gear, you can increase your speed
and range while applying the same amount of force.
For this reason, follow the gear change recommendations
provided by the indicators (g) and (h) on your display. If in-
dicator (g) is displayed, you should change to a higher gear
with lower cadence. If indicator (h) is displayed, you should
select a lower gear with higher cadence.
