Heat dissipation function - Aluminum alloy housing with a groove design for efficient heat dissipation. This helps protect internal circuits from overheating and maintains stability during extended use. It prevents thermal overload and increases the durability of the controller. Stable speed regulation - The sinusoidal drive for the brushless motor provides stable speed control, enabling smooth acceleration and deceleration. It supports precise braking and clean direction changes, making it suitable for vehicles that require constant performance. Temperature resistance - Constructed with temperature resistant wires and flame retardant materials for added safety. This design helps prevent overheating and reduces fire risk, supporting performance applications where safety is important. Broad compatibility - Suitable for electric vehicles, electric bicycles and electric trikes. Offers seamless integration with different models and configurations and is designed to perform reliably across multiple types of electric vehicles. Use scenarios - Commuting and touring on electric bicycles or e-trikes: maintain steady power and smooth response for comfortable daily travel and longer rides. - Mountain climbing and heavy load conditions: reliable thermal management and stable speed control under high demand. - Fleet, rental, or shared mobility services: repeated start-stop use with durable build and consistent performance across various model configurations.
