Best experience

Qiroll’s products have a unique technical design structure, based on the original electronic clutch technology. When the motor and the tire are not separated, it will not cause resistance to ordinary bicycles. Therefore the Qiroll structure and operation mode are unique in the field of friction boost. Smaller size, more simplified installation and more stable and efficient use of friction are the main benefits of Qiroll electronic clutch technology.
