charged on the bike, the charging
progress of both batteries will be in-
dicated on the display (the left-hand
battery is being charged in the illus-
tration). You can also tell by the
flashing indicator on the battery
which of the two batteries is being
charged at the moment.
Setting the assistance level
On the operating unit (9), you can set the level of as-
sistance you want the eBike drive to provide you with
while pedaling. 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 max-
imum:
– OFF: Motor assistance is switched off. The eBike
can just be moved by pedaling, as with a normal bi-
cycle. The push assistance cannot be activated at
this assistance level.
– ECO: Effective assistance with maximum effi-
ciency, for maximum range
– TOUR: Steady assistance, long range for touring
– SPORT/eMTB:
SPORT: Powerful assistance, for mountain biking
and for cycling in urban traffic
eMTB: Optimum assistance whatever the terrain,
rapid acceleration when starting from a standstill,
improved dynamics, top performance (eMTB is
only available in combination with drive units
BDU250P CX, BDU365, BDU450 CX and
BDU480 CX. This also requires a software update.)
– TURBO: Maximum assistance even at high pedaling
speeds, for biking sports

To increase the assistance level, press the + but-
ton (12) on the operating unit repeatedly until the re-
quired assistance level appears on the indicator (b).
To decrease the assistance level, press the – but-
ton (11).
The requested motor output is shown on the display
(a). The maximum motor output depends on the se-
lected assistance level.
When the on-board computer is removed from the
holder (4), the last indicated assistance level is
stored; the motor-output indicator (a) remains
empty.
Interaction between the eBike system and
gear-shifting
The gear-shifting should be used with an eBike drive
in the same way as with a normal bicycle (observe the
operating instructions of your eBike on this point).
Irrespective of the type of gear-shifting, it is advisable
that you briefly stop pedaling when changing gear.
This will aid the gear change and reduces 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 recommenda-
tions provided by the indicators (g) and (h) on your
display. If indicator (g) is displayed, you should

change to a higher gear with lower cadence. If indica-
tor (h) is displayed, you should select a lower gear
with higher cadence.
Switching bike lights on/off
On the model in which the lighting is powered by the
(10) eBike system, the front and rear lights can be
switched on and off at the same time via the on-board
computer using the bike light button (2).
(11)
Before starting each journey, check that your bike
lights are working correctly.
When the lighting is switched on, <Lights on> ap-
pears and when the lighting is switched off, <Lights
off> appears for approx. 1 s on the text indicator (d).
The lighting symbol (c) is displayed when the light is
on.
The on-board computer saves the light status and ac-
tivates this saved status accordingly after a restart.
Switching the bike lights on and off has no effect on
the backlighting of the display.
Switching the push assistance on/off
The push assistance aids you when pushing your
eBike. The speed of this function depends on the se-
Displays and settings of the on-board computer
Speed and distance indicators
The speedometer (f) always displays the current
speed.
You can choose from the following functions in the
function display (combination of text indicator (d)
and value indicator (e)):
– <Clock>: Current time
– <Max. speed>: Maximum speed achieved since
the last reset
– <Avg. speed>: Average speed achieved since the
last reset
– <Trip time>: Journey time since the last reset
– <Range>: Estimated range of the available battery
charge (at constant conditions such as assistance
level, route profile, etc.)

lected gear and can reach a maximum of 3.7 mph.
The lower the selected gear, the lower the speed of
the push assistance function (at full power).
The push assistance function must only be used
u
when pushing the eBike. There is a risk of injury if
the wheels of the eBike are not in contact with the
ground while using the push assistance.
To activate the push assistance, briefly press the
WALK button on your on-board computer. After acti-
vation, press the + button within 3 s and keep it
pressed. The eBike drive is switched on.
Note: The push assistance cannot be activated at as-
sistance level OFF.
The push assistance is switched off as soon as one of
the following occurs:
– You release the + button;
– the wheels of the eBike are locked (e.g. by applying
the brakes or hitting an obstacle);
– the speed exceeds 3.7 mph.
The push assistance function is subject to local regu-
lations; the way it works may therefore differ from the
description above. It can also be deactivated.
– <Odometer>: Total distance traveled with the
eBike (cannot be reset)
– <Trip distance>: Distance traveled since the last
reset
To switch between display functions, press
the i button (1) on the on-board computer or
the i button (10) on the operating unit repeatedly un-
til the required function is displayed.
To reset the <Trip distance>, <Trip time> and
<Avg. speed>, switch to one of these three functions
and then press and hold the RESET button (6) until
the indicator is set to zero. This will also reset the val-
ues of the other two functions.
