Electric Bike

Nothing compares to the simple pleasure of a bike ride. ~John F. Kennedy

The bicycle is just as good company as most husbands and, when it gets old and shabby, a woman can dispose of it and get a new one without shocking the entire community. ~Ann Strong

Electric Bike Care and Maintenance Instructions

This page is dedicated to providing instructions to care and maintain your OPTIMIST Electric Bike. To ensure longevity of your OPTIMIST motorised bicycle, please ensure you follow below instructions.

Safety Notice

Please do not use the electric bicycle before you carefully read the instructions below.

The motorised bicycle is weather proof, but not waterproof. Please ensure that the controller, the electric motor, the battery, or any electrical cables do not get submerged in water, this will cause irreparable damage to those electrical components that make up the ebike.

If you plan to not use the electrical bicycle for a long time, ensure the battery is charged to full capacity and place it in a cool and dry place. Then it is recommended to charge the onboard Li-ion battery at least once a month to prevent the Li-ion battery from deteriorating and becoming unusable.

Important: making a turn on foot, please ensure the E-Brake is engaged by slightly squeezing the left brake lever to avoid accidently engaging the electric motor. If this procedure is not followed, injury may be caused to the rider, other persons in the vicinity, or damage to surrounding properties.

Operation Procedures - riding the electric bike

Ensure the Li-ion battery is charged before you ride the ebike. As a guide, a fully charged battery will last approximately 40-50km in Pedal-assist mode. It is recommended that the battery is recharged well before the 40 km is reached in order to maximise the battery life, and to ensure the battery does not run out during a ride. As the OPTIMIST Electric Bike is a motorised push bike, you can also ride it just like a normal bicycle (should the battery run out).

The OPTIMIST ebike is equiped with an E-Brake System on the left hand side brake lever whereby the electric motor will be disabled whenever this brake lever is squeezed. This will avoid engaging the motor accidently whilst maneuvering the ebike on foot.
Check whether the brakes work properly before every ride.

At the end of a ride, turn the key to the OFF position in order to disconnect the power before parking the bike. This will prevent accidental activation of the throttle. In the case of an ebike equiped with a Water Bottle type battery, e.g. the Elite Sprinter Electric Bike; the OFF switch is located at the bottom of the battery.

Periodically check that there are no loose bolts and nuts in the bike, as this will compromise the safety of your ride.

It is recommended to pedal-start the electric bicycle and only gently turn the throttle as required. This will prolong the life of the lithium battery and electric motor.

Recommended weight limit is 100kg. Please ensure the load does not exceed this limit at any time.

Lithium Battery Charging Procedures for Electric Bikes

For a newly purchased electric bicycle, please charge the battery to full capacity before the first ride as the battery may become low after delivery, transportation and storage for some time. Please use electric drive only after the battery performance is confirmed.

The special charger supplied or designated to the particular OPTIMIST eBike model must be used, or otherwise the battery may be damaged during charging, or there is even risk of fire.

Charging Steps

Ensure the battery is charged to full capacity before your first ride.

Please carefully check whether the rated input voltage of charger is consistent with the voltage of power supply.

Ensure you plug in the charger into the electric bike battery before plugging it in the power main, otherwise a power short-circuit may result, which is likely to damage the battery. There is a power and charging indicators on the charger.

The battery may be charged when it is fixed on the bicycle or when it is dismounted and taken to an appropriate place inside a room.

It takes up to 6 hrs to charge the battery from empty, or 2-3 hrs when toping up. The charge indicator on the charger shows a red light if charging is in progress. When the charging indicator turns green the battery is full. It is recommended to continue to charge for approximately 1 hour after the Charging indicator turns green in order to charge the battery fully and extend the service life of battery.

When charging is complete, please disconnect the power supply plug from the main before disconnecting the charger from the battery.

Disconnect the charger from the power supply when it is not used to ensure prolonged service life and to prevent other risks. As a precaution when charging the battery, the use of a timer set to automatically switch off after a maximum of 7 hours is recommended.

Advice on Lithium Battery Protection for Electric Bikes

The consumers are kindly requested to pay attention to the following operation principles of battery protection.

Do not allow the battery to go flat. It is best to charge it every day if used. As you are supplied with a premium Li-ion battery, there will be no 'memory' effect from regular charging.

During the first 3-6 months of operation, a new battery should be charged to full capacity after every 10-15 km ride.

After the initial 3-6 months, the battery and the Optimist electric bike can be used for longer trips, but the battery life is extended to 2000 cycles if it is charged before it is 80% empty. To minimize electricity consumption and maximise battery range, rider should use the bicycle in Pedal-Assist mode as much as practicable, and only use the Throttle mode occasionally when required. This will also protect the battery and extend its service life.

When low voltage is indicated the electric power is used up and power shall be cut out and pedalling is required. At this point the power must be switched off at the ignition or switch (depending on the battery model) on the battery housing, and the battery must be charged as soon as practicable. In this case, you must not use battery powered drive before charging, as a second start will cause the battery to discharge excessively and may damage the battery, and shorten its service life. This type of misuse may not be covered under warranty.

Please do not put the battery near open fire or high-temperature heat sources. It is not recommended to put the battery under the sunshine directly.

Electric Bicycle Care and Long Term Storage

Please store the bicycle in a cool dry and well-ventilated place after you dismount the battery from the bicycle. Ensure the bicycle components are maintained clean, dry, and dust free.

The battery shall be charged to full capacity before storage and then recharged once every 20-30 days. The charger shall be put in a dry dust-free place.

Ensure tyres are inflated to recommended pressure prior to use.

Ensure brakes are checked, serviced, and/or replaced periodically to prevent unsafe riding.

Ensure wheels are periodically adjusted.

Bicycle oil may be applied to the drive system and chain time to time. To improve performance and reduce excessive wear.

Dismantling the motor, controller, charger, or battery will void the warranty.

It is recommended to have the bicycle checked and maintained at the Bicycle shop every 3-6 months, depending on usage.
Brake handles contain a switch, which automatically cut out the motor when applied. For this reason, these brake handles must not be replaced with ordinary brake handles.

Electric Bike Battery Disposal

The supplied Li-ion battery is made under high quality standards and should last a long time. However, there is a natural deterioration with any battery technology and a time will come that will signal the end of a battery life. Should this ever occur and you wish to dispose of the battery, please follow the battery disposal guidelines applicable to your local council.
