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
In the model in which the lighting is powered by the
eBike system, the front and rear lights can be
switched on and off at the same time via the on-board
computer with button (2).
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 light on and off has no effect on
the back lighting 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-
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).
u The push assistance function must only be used
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.

Displaying/adjusting basic settings
The basic settings can be displayed and changed re-
gardless of whether the on-board computer is in-
serted in the holder (4) or not. Some settings can
only be viewed and changed when the computer is in-
serted. Depending on the equipment of your eBike,
some menu items may not be present.
To go to the basic settings menu, simultaneously
press and hold the RESET button (6) and the i button
(1) until <Configuration> appears in the text indica-

tor to increase or scroll up. If the on-board computer
is inserted in the holder (4), it is also possible to
change the settings with the – (11) and + (12) but-
tons on the operating unit.
To exit the function and save a changed setting, press
the RESET button (6) for 3s.
