This high-performance electric sine wave controller is designed for universal e-bikes, enabling intelligent automatic voltage regulation from 36V to 60V without any configuration. It offers multiple riding modes, including a square wave mode for instantaneous torque response and a reliable emergency backup mode—sensorless mode. Equipped with SafeRide™ fault protection technology, the controller automatically switches to sensorless mode within 200 milliseconds in the event of a Hall sensor failure, maintaining 100% speed to ensure uninterrupted riding. With up to 94% efficiency, precise current control (±0.5A), and broad motor compatibility, it provides a fault-tolerant, adaptable, and smooth riding experience for every journey.
