QM-2 EBIKE KIT
Spring 2019 marks the beginning of a new chapter. Using data collected from years of in-house research and bikers’ feedback, we redesigned a new booster. QM-2 is a new type of supercharger designed with electronic clutch technology. Thanks to the addition of the electronic clutch technology, mechanical structure is not required to ensure the reliability of the entire booster. Its size is smaller than QM-1 and can be installed in more places. The pressure adaptive system makes installation easier. Just let the motor be close to the tire. At the same time the rubber-type friction material is used, so that the motor does not wear tires.
The power consumption of the electronic clutch system is also reduced to 70%. QM-2 is the best choice when using the booster.
Compared with previous products, our custom designed second generation of brushless motor and the third generation of control system can reduce the noise by at least 90%, almost 0 noise. It makes cycling easier. With our industry-leading systems and hardware, QM-2 provides secure, instant acceleration. This is an innovative product.
- 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.

QM-2 is designed to preserve the nature of every aspect of the bike. We can achieve this by designing the booster with a very small size and then design the battery into a Bottle.
The QM-2 is the smallest booster we designed. It can be installed in most frames to meet the needs of simple and reliable power. It is very hidden and difficult to find after installation.
It can be mounted in the middle of a classic steel frame bike and at the bottom of a new carbon frame. If you are riding more than 20 miles, it is recommended to purchase a high speed version.
Mountain bike installation requires attention to the tires. It is recommended to use continuous pattern tires to ensure sufficient friction.
Mountain bike riding speed is not fast. It is recommended to use low speed version.
The folding bike can be installed in the middle and bottom. It is recommended to use continuous tread tires to increase friction.
It can be installed in the middle and bottom of a city bike.
Place the QM-2 in the middle or bottom, place the battery in the bottle cage, and connect them with a hidden wire. Use the starter mounted on the handlebar to select the gear and activate the booster.
Retain tradition, accept new technology
The electronic clutch is a very interesting technique that eliminates the resistance in unpowered riding by controlling the state of the motor to achieve a separation effect. Although it consumes a little power, it is completely controlled, and 10% of the battery can support 10 minutes of electronic clutch operation, so it can be ignored. Or you can also choose the QR series with mechanical separation structure to meet the long-distance riding needs.
Ride Up To 25mile
Choose B60 battery pack (can be carried on board) to ride 15mile and choose B60i battery pack to ride 25mile. The two types of battery are not interchangeable.
Boost speeds up to 20 mph
QM-2 has 2 specifications: standard version with a maximum speed of 32km/h (with greater battery life and low noise performance)
High-speed version with a maximum speed of 48km / h (suitable for road bikes to pursue extreme riding speed)
Aluminum Alloy Frame
The CNC aluminum frame is very reliable and meets the special geometry of the booster. The classic simplified design ensures high reliability.
Second Generation Brushless Motor
A motor designed for the principle of friction assist, which increases power in very small sizes， meets 240 watts of power output and has a very large load capacity. And it has lower noise than similar motors.
Bottle Type Battery
Built-in battery protection chip and power display, low internal resistance 18650 battery and aluminum alloy insulated bottle ensures reliability.
There are different capacities to choose from, meeting the needs of 40-50KM. Aerospace-compliant models and long-distance cycling models are available.
