If you want more performance, recommend QR-E PRO, available in store. Some countries charge tariffs. North America is transported by logistics companies. Most European countries use free. Tarifflogistics channels, and QR-E is delivered to customers by European logistics warehouses using UPS. For some special bicycles. Please send us photos of bicycles. QR-E mute 250W double clutch booster. Electronic clutch and manual clutch. Total: 1.2 kg (QR-E + B60i battery). QR-E + B60i battery. Standard range (25 miles – B60i mixed mode). Suitable for bicycles: road bikes, off-road bikes (riding on asphalt roads), city bikes, folding bikes. Need 6 4CM space to install. It may take some DIY to send a photo of the bike for confirmation. Battery size: 60 190MM(B60). Tire tread pattern needs to be continuous. B60i bottle 25V 6ah battery. DC Changer 25V 2A. Travel distance: drive for 25 miles (pedaling Test data, subject to actual results). Speed: The maximum speed is 27 mph (Support speed). Cycling mode: 2 riding modes, from ECO to sports. B70 bottle 25V 9.6ah battery. 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. Passed safety certification, can be sent to Europe. The item “Electric Bicycle E-BIKE Conversion Kit Qiroll Friction Drive QR-E MUTE+ B60I Bat” is in sale since Wednesday, March 31, 2021.
