The charge level indicator on the display
unit does not display "full" after a complete
charge.
The battery is affected by the ambient
temperatures so that the battery
becomes too hot while being charged.
Allow the battery to cool down and
repeat the charge procedure. Also
observe the additional instructions on
charging the battery.
The charge level indicator on the display
unit does not indicate the charge level
reliably.
By discharging and charging the battery
frequently, the synchronisation between
the charge level indicator and the actual
charge level of the battery cannot be
calibrated. After approximately every 30
cycles, perform a full discharge.
The display unit displays an error code.
A fault has occurred in the drive system.
Jot down or remember the error code
and refer to a specialist workshop. The
error code makes it easier to locate and
fix the fault.
The system is permanently in generator
mode.
The brake sensor in the brake lever for
the front wheel brake does not respond.
Switch the drive system off and on
again. If this does not help, disconnect
the connecting cable from the brake
lever to the operating console at the
electrical connection. Have a specialist
dealer inspect the drive system right
away.
The lighting system does not work.
The battery does not have sufficient
charge. Check the charge status of the
battery and where necessary charge the
battery.
Electrical connections can come loose.
Check the fit of electrical connections on
the handlebars.
If the problem is not resolved with these
measures, refer to a specialist dealer.
