QR-E EBIKE KIT
Spring 2018 marks the beginning of a new chapter for QIROLL. Using data gathered from years of in-house R&D and riders’ feedbacks, we’ve built QR-E from the ground up. Every single component is designed and engineered specifically for the electronic booster.The QR-E, which inherits the classic QR series structure, retains the traditional mechanical structure and adds a new electronic clutch to make the operation more stable and fast.
Our custom-designed second-generation brushless motors reduce noise by at least 50%, increase power by 20% and efficiency by 15% compared to previous products. It makes riding easier.
With our industry-leading systems and hardware, QR-E delivers safe and reliable braking and instant acceleration. It is a classic product.
- Driven distance: Go up to 30 miles with the extended range battery.
- Speed: Get faster with a 27 mph top speed.
- Hill Climbing: Easily ride a 15 degree slope.
- Ride Modes: 2 ride modes, from ECO to Expert.
- Electric Clutch: Qiroll’s electronic clutch technology ensures a very stable boosting effect. It keeps touching the tires without resistance and can enter the operating state quickly and steadily.
- Mechanical Clutch: The motor can be adjusted to contact and disengage the tire with a knob. Separate the motor from the tire to achieve the desired effect when the battery is completely used up or if full human riding is desired.
- 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.

QR-E 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 QR-E has a unique swing arm structure that is more adaptable to the frame and can be mounted on most frames.
QR-E can support the structure of most mountain bikes with 2 optional installation positions.
Place the QR-E 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
Retain Mechanical Clutch
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 25 mph
QR-E 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.
Kettle Type Battery
Built-in battery protection chip and power display, low internal resistance 1860 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.
