1. [Excellent Performance]: The motor has relatively strong climbing ability, relatively low operating noise, and can reduce tire noise. 2. [Application Range]: It can drive sine - wave motors, rectangular motors, and is also suitable for Hall motors. It supports 48V - 60V - 64V compatibility and is applicable to electric bicycles, etc. 3. [Outstanding Upgraded Accessories]: The motor copper bars are relatively thick, the inductance accuracy is relatively high, the start is relatively smooth, and the riding is more comfortable. 4. [Exquisite Craftsmanship]: Our products are professionally manufactured, with relatively stable performance. The shell thickness is increased, the heat dissipation effect is relatively good, and the reliability is relatively high. 5. The controller torque is increased, the power is enhanced, the speed is relatively fast, the motor runs relatively smoothly, and the controller has a relatively long service life. 6.
