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.

This bicycle power-assist kit is compact and exquisite in design, and is highly concealed after installation. Whether it’s commuting or riding with a companion, the feeling of acceleration makes me feel great.
