Batteries and Battery Charging
Never modify the electrical system. Alterations may cause a fire, resulting in serious injury and could also
damage the electrical system. • Charge with the supplied charger only. Use of the wrong charger may
cause a
fire or explosion, resulting in serious injury. • Ensure the voltage and frequency of the charger is
compatible with mains electrical supply. • Use the battery charger in dry locations only. • The battery
must be charged before first use. • For maximum bat
tery performance and service life, charge the battery
after each use, and charge at temperatures between 0 and 40°C (32 and 104°F). • Battery charging
generally takes up to 4 - 8 hours from discharged to fully charged. Do NOT charge the battery
continuousl
y for more than 24 hours. • If the bicycle has not been used for over 4 weeks, charge the
battery before use. • Always switch the bicycle OFF after each use.
The battery pack can be recharged repeatedly. However, rechargeable batteries eventually need to be
replaced. A significantly reduced operating period after charging indicates that the battery is no longer
serviceable and should be replaced. Discard old batteries in an environmentally responsible manner.
The battery charger has a charge status LED indicator:
•
Red - Battery charging.
•
Green - Battery fully charged or disconnected.
To charge the battery:
Remove the battery from the bicycle, then plug the charger connector
into the charging port.
Connect the charger to a mains electrical supply and switch ON. The
indicator LED on the charger illuminates red to show the battery is
charging.
When the battery is charged (approximately 8 hours), the charger
indicator LED illuminates green. Disconnect the charger from the
electrical supply, then put the battery back to the bicycle.
Battery Storage
When storing the batteries for a long period of time:
Charge the batteries at least every 30 days to avoid capacity loss. Batteries slowly self-discharge when
unused over a long period. If the battery cells are left at a critically low charge state, the lifespan and
capacity will be permanently reduced.
Always disconnect the charger from the mains electrical supply and battery before storing the battery.
Avoid storing batteries in extreme temperatures, whether hot or cold. The recommended battery storage
temperature is between 0 and 25°C (32 to 77°F). Avoid exposing batteries to temperatures at or above
40°C (104°F) for extended periods.
Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this may
cause shorting or corrosion.
Tyre Pressures
The tyres must always be inflated to the correct pressure (as specified on the tyre sidewall) before every
ride. Riding the bicycle with either too low or too high pressures will affect bicycle performance, may
affect effective electrical assistance range, and may render the bicycle as dangerous. Use an accurate
pressure gauge when checking pressures.
Maintenance
Some maintenance activities described may be beyond the scope of some users. Do NOT attempt
procedures that you are not comfortable with, or do not have the necessary tools, experience or
knowledge for
–
take the unit to an authorised service centre or qualified technician for servicing. Items
