| Function Item| Function Description
---|---|---
1| Headlight Control| The headlights are turned on by default when the power is turned on. The headlights are turned off when the power is turned off.

The speed is limited to under 25 km/h.

3| Acceleration| When the power is on, the assist sliding speed exceeds 4 km/h (2.5 mph). When the handle is pressed, the system will control the rotation of the hub according to the depth of the handle press.

The lighter the press, the slower the speed, the faster the press, the faster the speed. The real-time speed is displayed in the first three words of the meter.

4| Brake| The brake is an electronic brake + drum brake. When the brake is pressed. the system controls the output electromagnetic brake and slows down gradually until the hub is locked.
5| Kick Start| The controller can drive the motor only when the speed of the kicking is above 4 km/h or 2.5mph.
