The LEDs of the battery charge indicator
on the battery go out. The capacity for as-
sisting the drive has been used up, and as-
sistance is gently switched off. The re-
maining capacity is made available for the
lighting and the on-board computer. The
indicator flashes. The capacity of the
eBike battery is enough for about two
hours of lighting. This does not account
for other consumers (e.g. automatic gear-
box, charging external devices from the
USB port).
If the on-board computer is removed from the holder
(4), the last displayed state of charge of the battery is
saved. If an eBike is powered by two batteries, the
battery charge indicator (i) displays the state of
charge of both batteries.
OFF
If an eBike has two batteries inserted
MPH
into it and both batteries are
KM/H
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.
