This high-performance electric square wave controller is designed for DIY enthusiasts, achieving a breakthrough by ensuring completely consistent forward and reverse speeds—power output, torque response, and top speed are identical whether going forward or backward. Reverse is no longer a “makeshift” backup mode, but a true full-speed reverse ride, allowing for reverse drifting. It achieves intelligent automatic voltage adjustment within a 48V to 84V voltage range without any configuration. It offers multiple riding modes, including a square wave mode for instant torque response and a sensorless mode as a reliable emergency backup. Identical forward and reverse speeds ensure balanced performance in both directions, meeting the needs of applications requiring precise reverse control. 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 and ensuring uninterrupted riding. High efficiency of up to 94%, precise current control (±0.5A), and broad motor compatibility guarantee a fault-tolerant, adaptable, and smooth experience on every ride.
