If the battery charge state falls below a minimum
level, the system switches off. No LEDs light up
on the control panel.
If you do not move your Pedelec for 10 minutes, the
system switches off automatically. If you subsequent-
ly want to ride using the assistance, you will have to
switch it back on via the control panel.
5.2 Troubleshooting
If faults are present, this is indicated on the control panel
by flashing battery indicator LEDs in the display.
CAUSE
SOLUTION
The speed sensor on
the chain stay is not
sending a signal to the
motor unit.
Make sure the spoke magnet
has not slipped. It should
be as close as possible to
the sensor on the chain stay
(max. 5 mm clearance).

Have the electric drive inspected regularly by your
specialist cycle shop. Do not carry out any work on
the electric drive or battery yourself. Unless you have
sufficient expertise this could lead to a serious ac-
cident. As a basic rule, always consult your specialist
cycle shop if you have a problem with the electric
drive or the battery.
You should only have the electrical components of
your Pedelec replaced with genuine parts. This makes
it safer for you and avoids problems when processing
warranty claims.
