Operation of Your Electric Bike

Your e-bike is driven by a motor embedded in the hub of the rear wheel .The motor is powered by a battery. The amount of power delivered to the motor, and hence the accelerating force on the e-bike, is controlled by you in a way according to the power-assisted mode you choose.

Electric -Assisted:

You must turn on the battery to use the e-bike in Electric-Assisted mode.
In the Electric-Assisted model, power assist is triggered when you pedal forward, and power assist stop when you stop pedaling. In other words, power assist happens as long as you pedal. You don’t need to pedal hard. All you need is to apply a light force to the pedals continuously to maintain the current flow. When you apply one of the brakes, power-assist will automatically stop.allowing the e-bike to slow down and stop.
You should use the SHIMANO gear shifter at the handlebar to set the gears appropriately according to road conditions and pedal as usual, you will find that you need to exert a lot less effort and the e-bike travels faster and at a more steady speed.

Adjustments and Maintenance

• Your e-bike is designed for regular road for a single person. Using your e-bike for extreme maneuvers, such as extreme off-road use, jumping, or carrying excessive load will damage the e-bike and could cause serious injury.

• Do not use high pressure water streams to clean your e-bike, as water might seep inside the motor or the wiring compartment and cause rusting of electric parts or short circuits. Please use damp cloth with neutral detergent to clean the bike body. Do not use alkali-based or canid based detergent such as rust cleaners as it may result in damage and/or failure of the bike body.

• Avoid parking your e-bike outside when there is rain or snow. At the end of a trip where there was rain or snow, bring the e-bike inside and use a clean, dry towel to eliminate any wetness.

• During daily use, please keep the controller clean and dry. Keep it away from water, vibration and contamination,
  Warning!
  Don not over lubricate. If oil gets on the wheel rims or the brake shoes, it will reduce brake performance and a long distance to stop the bicycle will be necessary. Injury to the rider or to others can occur.

• The chain can throw excess oil onto the wheel rim. Wipe excess oil off the chain. Keep all oil off the surfaces of the pedals where your feet rest.

• Using soap and hot water, wash all oil off the wheel rims, the brake shoes, the pedals, and the tires. Rinse with clean water and dry completely before you ride the bicycle.

• Using a light machine oil (20W) and the following guidelines, lubricate the bicycle:

Pedal| Every 6 months| Put 4 drops of oil where catch pedal axle goes into the pedal
---|---|---
Chain| Every 6 months| Put 1 drop of oil on each roller of the chain
B.B.| Every 6 months| Contact a professional technician
Motor| Every 1 year| Contact a professional technician

Some instructions on battery maintenance and charging

1. If you leave the battery pack in your stock in less energy condition, it will sleep to die easy. So please charge the battery pack full after each long distance ride. Do not charge the battery for a long time (that is “exceeds 10 hours”) in summer; in case that the battery will be calor ifacient and broken.

2. Perform a full discharge of the battery (ride your e-bike until the battery is completely empty) after 15 normal charges or every three months, this will help to increase the life of the battery. The charging time is about 6-8 hours per charging cycle.

3. If the bike is not used for more than a month, it is best to store the battery as follows:
   At 40% -60% of its capacity, recharge once a month for 30 minutes.
   If the battery is not in use, it should be checked once a month. At least one LED should blink to indicate that there is still charge. Charge the battery if necessary.
