Our company has been engaged in the research of direct-current dynamo drive for any years. We have developed PIC116F72, NEC9234, XC846 (Infieon) and X8m06-A single chips with MCU program design, utilizing the newest scientific research fruit to these projects. So we can produce multifunctional and good quality electric bicycle controllers. Our company has special designs and uses highly-efficient PID CEE-type algorithm to timely deal with controller over current. Therefore, we effectively guarantee that electric vehicles can work with the conditions of high heat and low shock and electromagnetism disturbance. In recent years, our company has produced electric vehicle controllers with first-class quality, complete product specifications, good performance, reliable quality and reasonable prices based on extraordinary designs and superb technology. Therefore, they are favored by the majority of customers.
