C203

Rated parameters of 36V/48V ,200-350W; current limit of 15A; sinusoidal FOC control; can adapt to wheel diameter of 16 ~ 28 inches; protection grade reaches IP66. The size of the body is designed according to the size of a matchbox; the weight (without harness) is only 90g. The software and hardware platform was designed to guarantees its high quality, high reliability and continuous stability; it can achieve long-term operation of 500W power in normal temperature environment and 350W power in 40 ℃ high temperature and humidity environment. Compatible with torque, cadence sensor, Hall or Hall-less motor; based on the full visual debugging platform, the adjustment state of high efficiency, low noise, low jitter and low delay is achieved. It can be adapted to many types of vehicles such as city, mountain, travel and road bikes.
