The electronic clutch is a virtual clutch. The way of working is that the motor is not separated from the tire (not through mechanical parts) and the electronic is used to eliminate the resistance of the motor.

Manually separate the motor from the tire only when the booster is not in use.

This way of working is a revolutionary improvement to the friction booster, unlike other similar products.

Electric Clutch: Qiroll's electronic clutch technology ensures a very stable drive. It comes into contact with the tire without resistance and can enter the operating state quickly and steadily.

Mechanical Clutch: The adjustment knob separates the motor from the tire when the battery is completely depleted or needs to be self-riding.

Flexible use: The booster is not something that can't be changed and can be easily removed without using it. With electronic clutch technology, installation and adjustment is very simple.

Reliability: The second generation of motors has a larger margin and the motor life is also very long. In extreme cases, the internal controller actively cuts off the power to ensure safety.

Reliable system: QR-E components are designed for friction assist. After years of testing and market feedback, they are reliable, stable and easy to install.
