When the chain of the rear derailleur rubs against the tires how to do? How to deal with the latter’s rear derailleur bending ?

  1. Just push the rear derailleur to the outside to make the chain and the tire have a distance of 1-2CM.

  2. Disassemble the rear derailleur directly, there is a white metal, you need to move it 1-2cm outside, and then reinstall the rear derailleur
    It is recommended to directly adopt scheme 1, which is simple and effective, and will not affect the use of functions

  3. If the silver metal fish hook is bent and deformed, the rear derailleur should become stuck. You can replace the silver metal fish hook or directly hammer it to become straight.

How to remove the battery?
Insert the key into the base of the steel tube, then press the key inwards, and finally rotate to unlock,and finally pull the battery bracelet to remove the battery.

Read This First: Safety and Compliance with the Law
Congratulations on your purchasing of your new e-bike. Your new e-bike is an excellent piece of personal transportation equipment that will give you good service for many years.
Before you start using your e-bike, we want you to be aware of a few important points. Please read this section carefully.

  • Observe Laws Regarding the Use of Battery-Operated Bicycles
    Your e-bike is designed and manufactured to meet safety requirements as a battery-operated bicycle. However, state and local laws governing the use of battery-operated bicycles on public roadways, parks, and other open areas may differ. Please check with your local authority before using your e-bike in public areas.

  • Observe Laws Regarding the Use of Bicycles
    Note that all laws regarding the use of bicycles in public areas, such as those mandating the use of helmets and the use of infant seats, will automatically apply for e-bikes. Check with your local authority on what restrictions might apply.

  • The Lithium-ion Battery of Your e-Bike
    Your e-bike is equipped with the latest battery technology. The lithium-ion battery is much lighter than lead- or nickel-based batteries that are being used in some older models.

  • Your First Ride
    Please be VERY CAREFUL when you are ready to get on your e-bike for the first time because that the e-bike moves significantly faster than a regular bicycle at active power-assisted mode. Take your e-bike to an area with a lot of open space before you start. Do not start pedaling hard as soon as you get on the e-bike (as you normally would so with a regular bicycle), as the e-bike will accelerate under pedal-assist mode and you may be unprepared for the sudden increase in speed.
    However, after a few times, you will enjoy using the pedal-assisted function.
    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.
    You can configure the e-bike to operate in the pedal-assist-only-mode or the full power mode (should check against local laws to ensure full power mode is permitted) where you can also use the hand throttle to deliver power to the motor.
    The e-bike is factory-configured to operate in the pedal-assist-only mode.

  • Your First Ride
    (Reprinted from the Safety and Compliance with the Law section)
    Please be VERY CAREFUL when you are ready to get on your e-bike for the first
    time because the e-bike moves significantly faster than a regular bicycle at active
    power-assisted mode. Take your e-bike to an area with a lot of open space before
    you start. Do not start pedaling hard as soon as you get on the e-bike (as you
    normally would do with a regular bicycle), as the e-bike will accelerate under
    pedal-assist mode and you may be unprepared for the sudden increase in speed.
    However, after a few times, you will enjoy using the pedal-assisted function.

  • Pedal-Assisted
    You must turn on the battery to use the e-bike in pedal-assisted mode.
    In the pedal-assisted mode, power assist is triggered when you pedal forward, and power assist stops 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. Power assist will turn itself off when the e-bike has reached the maximum speed of 18 mph.
    You should use the 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.

  • Hand Throttle Control
    In the hand throttle mode, amount of power assist is determined by the throttle switch controlled by your right hand. You control the throttle by twisting it from its resting position, the farther the throttle switch is from its resting position, the more power is delivered to the motor to accelerate the e-bike. When you want to slow down, you simply release the throttle and let it return to its resting position, and simultaneously apply the brakes if necessary.
    You do not need to pedal the e-bike if you use the hand throttle. However, you can pedal while commanding power assist. If you do pedal to help the movement, you conserve energy and the charge in the battery will last longer.

Care and Maintenance for Your New e-Bike
You should, in general, take care of your e-bike the way you would with a regular bicycle by keeping it dry, clean and the moving parts well lubricated. You should also avoid parking your e-bike in exposed areas whenever possible.
You should check the effectiveness of the brakes before each use.

  • For your e-Bike, you should also take note of the following:

  • Your e-bike is designed for regular country road use for a single person.
    Using your e-bike for extreme maneuvers, such as extreme off-road use, jumping, or carrying the 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 electrical parts or short circuits.

  • 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.

  • Be sure you do not lose both keys and remote controls. If you lost one key, you should immediately make a copy as a back-up. If you lost both keys, you will be unable to remove the battery from the e-bike. If you lost both remote controls, you can’t turn on the bike.

  • Special Care for the Battery and the Charger

  • Use only the supplied charger to charge your battery. Do not use an unauthorized substitute. If your charger is lost or damaged, contact your dealer to order a replacement.

  • Do not open or alter the battery or the battery charger.

  • Do not place the battery near fire or corrosive substances. Do not immerse in water or other liquids.

  • Avoid subjecting the battery from high temperatures, such as directly under the hot sun, for prolonged periods of time.

  • Do not connect (short circuit) the two poles of the battery.

  • After much use, your battery’s charge holding capacity will decrease. If you find that your battery does not hold sufficient charge even for short trips, you should contact your dealer to order a replacement. Under normal use, the battery will undergo 1000 charging and discharging cycles.

  • If the battery will not be used for an extended period of time, charge it fully and recharge it every 3 months. Store it in a cool place.
    ² Your e-bike battery is engineered with precision for high capacity and long useful life. We do not recommend that you use it to power other electrical devices. Improper use of the battery will damage the battery and shorten its useful life and may cause a fire or an explosion.
