Product Description

Mid Motor With Torque Sensor By Self-developed


The mid motor with torque sensor is exquisitely designed, and the self-developed nano-scale torque sensor adopts the strain gauge technology. Compared with the traditional reverse magnetostrictive shrinkage material, the sensitivity is improved by more than 35%, and the power control is better. At the same time, it is exclusively produced by GE's companies in the United States, and the level of technology is on the same level as GM.


Main Features


1. Brushless, long life (bearing life), maintenance free;


2. The motor has no mechanical commutator to prevent dust from entering the motor and has high reliability;


3. Large power and simple structure;


4. Excellent starting performance, no hysteresis damping consumption kinetic energy, strong torque climbing ability;


5. High efficiency, low power consumption, and relatively long mileage;


6. High performance price ratio


7. Excellent waterproof performance.

1. Q: What is the E-bike motor kit?

A: The kit is designed to transform your standard bicycle(manual pedal power)to an electric-powered by a motor and battery pack.


2. Q: Will the conversion kit fit my bicycle?

A: The conversion was designed to fit 90% of the bicycles, and you can check your bicycle fork(the two metal pieces that attach the wheel to the bicycle) to be sure. You will need at least 100mm for front wheel and 135mm for rear wheel.


3. Q: If my bicycle meet your standard, how can I choose to install front wheel or rear wheel motor?

A: A front hub kit is normally much easier to install than a rear wheel kit since you don't have to worry about gearing or derailers. When riding, the rider can easily see the front wheel and respond quickly to problems such as wheel spinning.

Rear wheel drive has the advantage of better traction which is great for hills and inclines. And because the rear frame dropouts are normally stronger than the front fork dropouts, a rear wheel can handle more torque and increased power.


4. Q: How fast will it go?

A: The speed would be decided by the motor power, controller and battery spec. According to different countries rules, we provide 25km/h for EU and AU market, provide 30km/h for other market.


5. Q: How far can I go on one charge?

This varies depending on usage, your specification will affect the your battery performance and life. And mostly of the battery have a cycle life of more than 700charges.


6. Q: How long does it take to recharge the battery?

A: usually it takes 4—6 hours.


7. Q. When should I recharge batteries?

A. The battery can be charged after every ride. We do recommend that every 20th charge that you run the battery flat and give it a full charge.


8. Q: How should I store my battery?

A: Store in cool dry place, you should fully charge your battery before storing it.


9. Q: How can I get the best battery performance and range?

A: Pedal while the motor is on, start the motor after the bike is moving, use the motor mainly to climb hills, and don’t use the motor while you are going downhill.
