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.

Reduce tire wear.

Frequent separation from the tire increases wear. With electronic clutch technology, motors and tires do not need to be separated frequently to reduce tire wear. This technology can also improve operating efficiency and extend driving distance.

Electronic control

A built-in DSP processor controls the operating state of the booster, electronic clutch, power control, and regulated operating mode. All under control.

Start response fast

Traditional separation structures require a “contact” action to transmit power. Electronic clutch technology allows the motor to stick to the tire, so that the response is faster, in just 0.1 seconds.

New friction material.

The new sticker-based friction material, developed on the basis of polyurethane materials, is the same material as the tires and does not damage the tires. It is easy to replace.
