Smart Tips:
- Please always pedaling your bike before giving electric power to avoid
over-discharging battery and save battery life.
Never apply power when stopping and braking that may damage battery
Travel distance is depended on how do you control your power. This is a power assistant bike. please use pedal on uneven road, or up slope to save battery energy and get longer running.
Note: To determine the size of the wheel you need for your bike, do NOT measure your rim. The wheel size is the rim with the tube and tire installed and inflated. Look on your bicycle tire for the wheel size. It should read something like this: 1.75 (width) X 26 (diameter). This would mean you have a 26" bike. Please click here to view the dimension of the fork that must fit a 26" rim.
Installation Instruction:
1. Please check the polarity first before installing the E-bike kits. Wrong polarity will damage the controller and we don't provide warranty for that.
2. Charge the battery immediately after use.
3. When charging Battery Pack, please put battery in a fire proof container. Always charge in an isolated area, away from other flammable materials. Ex: wood bench, carpet. Never charging the Battery Pack unattended.

The advantages of riding an electric bike:
- Get the experience of riding a bicycle without sweating.
- Use an e-bike for local errands. Why drive a 6,000 lb S.U.V. - 2 miles to the corner store or post office when an electric bicycle will get you there in the same amount of time - without the wear and tear on your car, and without polluting our atmosphere?
- Use an electric bike to commute to work. If your one-way commute is 10 miles or less, why not ride an e-bike instead of driving? If you take surface streets, you'll probably arrive at work the same amount of time it would've taken you to drive. Perhaps even less if you must fight morning and afternoon traffic, since a bicycle is much more maneuverable.
- Get a little exercise. Even though your bike is electric; you can still pedal along with it as much as you care to.
Laws governing electric bicycles: There are new federal guidelines concerning electric bicycles, and each state/municipality will have codes of their own. Suffice it to say: electric bicycles powered under 750 watts - that do not exceed 20 mph - are generally still classified as a "bicycle", and will not have restricted use.
