Battery Charge-control Indicator
The battery charge-control indicator i displays the charge
level of the eBike battery pack, not that of the on-board com-
puter's internal battery pack. The charge level of the eBike
battery pack can also be checked on the LEDs of the battery
pack itself.
On indicator i, each bar of the battery pack symbol is equiva-
lent to a capacity of approx. 20 %:
The eBike battery pack is fully charged.
The eBike battery pack should be recharged.
The LEDs of the charge-control indicator on the
battery pack extinguish. 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 capacity of the eBike battery pack is enough for about
2 hours of lighting. This does not account for other consumers
(e.g. automatic gearbox, charging external devices at the
USB port).
If the on-board computer is removed from the holder 4, the
last displayed battery charge level is saved.
Setting the Assistance Level
On the operating unit 10 you can set how much the eBike
drive assists you while pedalling. The assistance level can be
changed at any time, even while cycling.
Note: For individual versions, it is possible that the assistance
level is pre-set and cannot be changed. It is also possible that
less assistance levels are available for selection than listed
here.
The following assistance levels (max.) are available:
– "OFF": The motor assistance is switched off, and the eBike
can be moved as a normal bicycle only by pedalling. The
push assistance/start assistance cannot be activated in
this assistance level.
– "ECO": Effective assistance at maximum efficiency for
maximum cruising range
– "TOUR": Uniform assistance, for touring with long cruising
range
– "SPORT": Powerful assistance for sportive riding off road
as well as for urban traffic
– "TURBO": Maximum assistance, supporting highest ca-
dence for sportive riding
To increase the assistance level, press the "+" 13 button on
the operating unit until the desired assistance level appears in
the display b. To decrease the assistance level, press the
button"–" 12.

* The motor output can vary for individual versions.
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.
Switching the Push/Start Aid On/Off
With the speed version, the push aid can also be used as a
start aid. The start aid is switched off at 18 km/h.
The push/start aid can make it easier for you to push or start
the eBike. The speed of this feature depends on the selected
gear and depending on the model, can reach a maximum of
6 km/h or 18 km/h. The lower the selected gear, the lower the
speed of this function (at full capacity).
 The push/start aid function may only be used when
pushing or starting the eBike. If the wheels of the eBike
have no contact with the ground when using the push aid,
then there is risk of injury.
To switch on the push/start aid, press and hold the "WALK"
14 button on the operating unit. The eBike drive is switched on.
Note: The push assistance/start assistance cannot be activat-
ed in the "OFF" assistance level.
The push/start aid is switched off if one of the following
occurs:
– you release the "WALK" 14 button,
– the wheels of the eBike are blocked (e.g. by actuating the
brakes or impacting against an obstacle),
– the speed exceeds 6/18 km/h.
Switching bike lights on/off
In the model in which the lighting is powered by the eBike sys-
tem, 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" appears and
when the lighting is switched off "Lights off" appears for ap-
prox. 1 s in text indication d. The lighting symbol c is dis-
played when the light is on.
Switching the bike light on and off has no effect on the back
lighting of the display.
Version Speed: Daytime running lights are always provided
in this option. When you switch on the eBike system (see
"Switching the eBike System On/Off", page English–3), the
lights will also be switched on. The bike lights cannot be
switched off with button 2.
