5 smart assist modes

We have spent 5 years on developing and optimizing the assist system. The assist system is based on the speed, acceleration, the road slope, and also the assist level that you set in the APP or on the wireless display, calculating out the power you need. It will assist you automatically when you pedal. And we will keep on optimizing the system and publish it from time to time. You will be able to update the system by the APP.

Dedicated APP provides you wonderful cycling experience

You can use the APP to control the wheels, upgrade the firmware, set the assist mode, set the assist level, calibrate the gyroscope angle, and detect the fault. And also you can check the speed, temperature, power, mileage, etc.

Speed up to 32km/h
Speed limitation is settable in the APP.

The default maximum speed is 25km/h, you can set the speed limitation up to 35km/h in the APP.

Anti-theft Tracking Function: Lost bike tracking. You can report lost when your bike is stolen.

After you report lost, once the thief tried to connect the wheel with the APP, the system will locate the mobile phone, disable the motor immediately and upload the information to the server.

Overspeed alarm makes it safer to ride

You can set the overspeed alarm value in the APP. It will alram when the speed is over the value you set.
