Bafang launch H700 built-in automatic dual speed drive system

e-Bike drive system manufacturer, Bafang, has announced the launch of the built-in H700 automatic dual speed rear drive system, which is scheduled to launch in the third quarter of 2021.

Bafang’s development team has successfully integrated the transmission into the motor, achieving a highly-integrated built-in automatic dual speed motor which also integrated with an automatic dual speed system. Additionally, the motor automatically adjusts the gearbox ratio by detecting the speed in which the rider is cycling.

With a weight of 3.2kg, a maximum outer diameter of 136mm and standard OLD of 135mm, the H700 rear motor can be adapted to the standard eBike sizes for both belt and chain transmissions. In addition, the motor wiring is on the left side of the outlet structure to enable a concealed harness inside the frame to avoid unnecessary scratches.

Bafang designed the system with a smooth and non-marking outer tube. The 10Ah intube battery and controller are integrated into the downtube to enable a more stable structure; the single-button display is embedded on the tube to result in easy operation and full release of the handlebar space.

More information can be found on the Bafang website.

The H700 drive system will be presented at the 2021 Eurobike. The Bafang booth is: A1-303.
