[Excellent performance]: The motor has strong climbing ability and low motor running noise, eliminating tire noise. [Scope of application]: Can drive sine wave motors, rectangular motors, and also suitable for Hall motors, can support 48V-60V-72V general, suitable for electric bicycles, electric scooters. [Outstanding upgrade accessories]: The drive motor has thicker copper bars, higher inductance accuracy, smoother starting, and more comfortable riding. [Exquisite workmanship]: Our products are professionally manufactured, with stable performance, increased shell thickness, and better heat dissipation. High reliability. The uphill torques of the controller is increased, the power is strengthened, the speed can be faster, the smoothness of the drive motor is better, and the life of the controller is longer.
