Applicable to Electric Bicycles, Cargo. The range extender can generate power, collect cadence signals, collect pedaling force data, and simulate bicycle resistance, among other functions. The range extender motor adopts FOC (Field-Oriented Control) algorithm to simulate cycling resistance, making the riding experience feel more realistic and smoother. Through electrical transmission, it achieves a physical-free drive system, simplifying production and assembly. It also enables long-distance energy transfer and multi-actuator control.
