This intelligent square-wave controller kit is designed for a wide range of compatible e-bike systems. It features automatic voltage recognition from a wide range of 36V to 72V, ensuring immediate installation and operation without manual setup. It offers two drive modes: square-wave mode for robust torque output and sensorless square-wave mode as a fail-safe. This mode can be switched manually or automatically in the event of a Hall effect sensor failure.

The kit features a SpeedDial™ waterproof OLED display with real-time adjustable speed limits between 25 and 80 km/h, meeting diverse riding needs. Utilizing the latest generation Hall Effect System 2.0 technology, it automatically recognizes both five- and six-wire Hall effect sensors, eliminating the need for jumpers or additional configuration. If a Hall effect failure is detected, the system seamlessly switches to sensorless square-wave mode within 300 milliseconds, maintaining 100% output power and reducing startup vibration to less than 2 seconds, significantly improving system reliability.

This product’s forward-thinking design ensures broad motor compatibility and efficient control, combining high performance with high reliability, making it ideal for daily commuting and high-power e-bike riding.
