8.1.4 Display "E9"

If "E9" is displayed, the following cause/solution may
apply:
› A problem occurred with the drive unit. Contact
your specialist cycle shop if this occurs.
If "E9" is displayed the distance covered will not
be recorded. It will therefore no longer be possible
to adjust the assistance control and the power as-
sist will no longer work.

8.1.5 Assistance control indicator flashing

If the assistance control indicator is flashing although the
battery charge is sufficient, the following cause and solu-
tion may apply:
› The drive unit is overloaded / overheated. The
battery management has switched itself on and
reduced the assistance. A short period follows in
which the drive recovers after which the full assis-
tance output is available once again.
If this does not happen, contact your specialist
cycle shop.

Error code

8.1.6 Additional possible sources of errors

› If you only pedal very gently, the power assist is
not enabled.
› If the motor is not running and you cannot pinpoint
the cause, check the buttons, cables and plugs of
the electrical system.
If you find a break or a crack, do not try to repair the
fault yourself. Take your Pedelec to a specialist cycle
shop.

9 Cleaning

Remove the battery before you clean your Pedelec.
We recommend you clean your Pedelec with a damp cloth,
a sponge or a brush. You can obtain suitable cleaning
agents and additional information from your specialist
cycle shop.
Make sure when cleaning that water does not enter the
battery. Although the electrical components are sealed,
it is not advisable to clean the bike by spraying it with a
hose or a high-pressure cleaner. This could damage your
bike.
When wiping down the battery, be careful not to touch and
connect the contacts on the underside. This could cause
the battery to switch off.
