This high-performance Electric Sine Wave Controller is engineered for universal e-bike compatibility, offering intelligent voltage autopilot from 36V to 84V with zero configuration required. It delivers versatile riding modes including Sine Wave for ultra-smooth and quiet operation, Square Wave for instant torque response, and Sensorless mode as a reliable emergency backup. Equipped with SafeRide™ fail-safe technology, it automatically switches to sensorless operation within 200ms upon Hall sensor failure, maintaining 100% speed for uninterrupted rides. With high efficiency (up to 94%), accurate current control (±0.5A), and broad motor compatibility, it ensures a fault-tolerant, adaptable, and smooth riding experience for every journey.
