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 empty off power, 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.
This is the newest generation of motors, that has a larger margin and the motor life outstanding. Now with auto cut-off. In extreme cases, the internal controller actively cuts off the power to ensure safety.
QR-E components are designed for friction assist. After years of testing and market feedback, they are reliable, stable and easy to install.
- Drive Distance: The battery can reach 20-30 miles with extended range (dependent on battery).
- Speed: Speeds up at a maximum speed of 20 miles per hour.
- Climbing: Easy to ride 15% slope.
- Cycling mode: 2 modes of riding from eco to expert.
- Electric Clutch: Qiroll’s electronic clutch technology ensures a very stable pressurization effect. It contacts the tyre without resistance and can enter the running state quickly and stably.
- Technology Mute: The most advanced technology application, completely eliminate the motor noise
- Flexible Use: Installing the booster is not an irreversible thing, it can be easily removed without using it. Thanks to the electronic clutch technology support, installation and adjustment is very easy.
- Reliability: The second generation of motors has a larger margin and the motor life is quite long. In the extreme case, the internal controller actively cuts off the power to ensure safe cycling.
