This advanced sine wave controller kit is engineered for universal e-bike compatibility, offering intelligent auto-voltage recognition from 36V to 72V with zero manual configuration. It supports triple-waveform operation—sine wave for ultra-smooth and quiet rides, square wave for high-torque demands, and sensorless square wave as an instant failsafe—allowing manual selection or automatic fallback in case of Hall sensor failure.

Equipped with a SpeedDial™ waterproof OLED display, it enables real-time speed limiting programmable between 25-80 km/h. The innovative Hall System 2.0 offers automatic detection and compatibility with both 5-wire and 6-wire Hall sensors without jumpers. In the event of a fault, the system switches to sensorless square wave mode within 300ms, maintaining 100% speed with under 2 seconds of startup vibration for uninterrupted and reliable operation.

Designed for future-proof performance, it ensures broad motor support, high efficiency, and robust control—making it ideal for everyday commuting and high-power cycling applications.
