Remove the bike from the obstacle,
power o , and power on again to
resume riding.
The voltage supplied by the battery is
too low to operate the bike. Charge
the battery and try again. If the issue
persists, check the voltage output on
the battery terminals using a volt meter.
If a fully-charged battery does not
output the correct voltage on the volt
meter, battery needs to be replaced.
Make sure you are using the correct
battery for your bike. For example, the
48V Pace 500 battery cannot be used
to power the 36V Pace 350 ebike, even
though they look similar.
Check all cable connections between
the controller and the display and that
the connectors are undamaged and not
contaminated with grit. If this does not
resolve the issue, replace the display. If
the bike does not work correctly with a
new display, replace the controller.
