Take care to ensure that the battery does
not get too hot. Battery ageing increases
sharply with temperatures above 40 °C.
Being placed directly in the sun’s rays can
cause a battery to heat up considerably.
Take care to ensure you do not leave the
battery in a hot car and park your bike in the
shade during bike rides. If you cannot avoid
the heat, make sure you do not charge the
battery at the same time.
A fully charged battery ages at an even high-
er rate at high temperatures than a partially
charged one.
If you ride constantly using maximum motor
power, you motor will always need a higher
current. Higher currents cause the battery to
age faster.
You can also increase the service life of your
battery by using the assistance judiciously.
Cycle using a low assistance setting. Low-
er discharge current draws will save your
battery.
Charge the battery to around 60% (3
to 4 charge indication LEDs lit), before
storing it for a long time. Check charge
status after 6 months. If just one charge
indication LED is still lit you will need to
recharge the battery again to around 60%.
If the battery is stored fully dis-
charged for a long time, it may be
damaged despite the low self-discharge
rate and charge capacity may be substan-
tially reduced.
It is inadvisable to leave the battery connect-
ed to the charger for long periods.
The Shimano Steps mid-mounted motor is a
durable and maintenance-free drive unit. It is
nevertheless a wearing component which is
covered by a two-year warranty. As a result
of the added performance, the wearing com-
ponents such as the drive unit and brakes
are subjected to higher loads than on a
conventional bike. Components wear faster
due to the effect of increased power.
