Assistance is not being
provided.
Is the battery sufficiently charged?
Check the battery charge. If the battery is
nearly spent, recharge it.
Are you riding on long slopes in summer
weather or riding for a long time carrying a
heavy load?
The battery may be overheating.
Turn off the power, wait for a while and
then check once more.
The drive unit, cycle computer or assist
switch may be connected incorrectly or
there may be a problem with one or more
of them.
Contact the place of purchase.
Is the speed too high?
Check the cycle computer display.
Assistance is not provided at speeds set by
the manufacturer or more.
Are you pedaling?
The bicycle is not a motorbike, so you need
to operate the pedals.
Is the assist mode set to [OFF]?
Set assist mode to a mode other than [OFF].
If you still do not feel that assistance is
being given, contact the place of purchase.
Is the system power ON?
If you have performed the steps below and
still do not feel the assistance, contact the
place of purchase.
Use the power switch on the cycle computer
or the battery power button to turn the
power back on.
Assist traveling distance is
too short.
The traveling distance may become shorter
depending on road conditions, the gear
position and total light usage time.
Check the battery charge. If the battery is
nearly spent, recharge it.
The battery characteristics will drop during
winter weather.
This is not a sign of a problem.
The battery is a consumable part. Repeated
recharging and long periods of use will
cause the battery to deteriorate (lose its
performance).
If the distance that can be traveled on a
single charge is very short, replace the
battery with a new one.
Is the battery fully charged?
If the distance that can be traveled when
the battery is fully charged has decreased,
the battery may have degraded. Replace
the battery with a new one.
