Symptom
Assist traveling distance is
too short.
Pedaling is stiff.
Lights
Symptom
The front light or the tail
light does not illuminate
even when the switch is
pressed.
Other
Symptom
When using an electronic
gear shifting, I feel that the
level of assistance weakens
when the gears shift.
Sound occurs after gear
shifting.
A noise can be heard from
the rear wheel during
normal riding.
Cause / Possibility
The traveling distance may become shorter
depending on road conditions, the gear
position and total light usage time.
The battery characteristics will drop during
winter weather.
The battery is a consumable part. Repeated
recharging and long periods of use will
cause the battery to deteriorate (lose its
performance).
Is the battery fully charged?
Are the tires inflated to a sufficient pressure?
Is the assist mode set to [OFF]?
The battery may be running low.
Cause / Possibility
The E-TUBE PROJECT settings may be
wrong.
Cause / Possibility
This occurs because the level of assistance is
being adjusted to the optimum level by
computer.
Gear shifting adjustment may not have
been carried out correctly.
Check the battery charge. If the battery is
nearly spent, recharge it.
This is not a sign of a problem.
If the distance that can be traveled on a
single charge is very short, replace the
battery with a new one.
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.
Inflate the tire with a bicycle pump.
Set the assist mode to a mode other than
[OFF]. If you still do not feel the assist,
contact the place of purchase.
Check the assistance again after sufficiently
charging the battery. If you still do not feel
the assist, contact the place of purchase.
