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. 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. 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.
