The requested drive power appears on the dis-
play (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 dis-
played is saved; the drive power indicator (a) re-
mains empty.
Interaction of the drive unit with the gear-
shifting
You should shift through gears on an eBike in the
same manner as when using a normal bicycle (ob-
serve the operating instructions of your eBike with re-
gard to 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 re-
duce 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
(9)
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
(11)
computer using the bike lights button (2).
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.
