Ultra smooth upgrade for all electric trials bikes.

Kelly KDS programmable small series/PM motor controller provides efficient, smooth and quiet controls for electrical tricycle, electric motorcycle, pump motor, and industry motor speed control. Motor speed controller uses high power MOSFET, synchronous rectification, fast PWM to achieve high efficiency. Powerful microprocessor brings in comprehensive and precise control to brushed motor controllers. This programmable motor brushed controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

Provide free male or female connectors matching with KDS controller.
