1、Material: The controller housing is made of aluminum alloy to protect the internal circuit. Conducive to heat dissipation and avoid thermal overload. 2、Features: Brushless motor controller, which can provide stable speed, quiet operation, sensitive braking and direction change control. More efficient and energy efficient. The phase angle and rated voltage of the electric bike can be automatically recognized. 3、Dual Mode Operation: When the motor Hall is normal, it works in the Hall mode, and when the motor Hall is abnormal or damaged, it switches to work without the Hall mode. 4、Ease of Installation: The cables and connectors are durable, ensuring a low failure rate for extended use. Each interface has a different color for your convenience. 5、Applicability: Suitable for electric bikes, electric tricycles, electric four wheeled vehicles, electric motorcycles, etc., as long as the power and voltage match.
