Bafang has introduced a new e-bike rear hub motor, which will debut at the Eurobike 2017 show.
The H800 gear-drive rear hub motor, which is available with either a 350W or 500W output and a max torque of 55 Nm, features a modern MTB thru-axle design with Boost standard.
This makes the hub compatible with both sports oriented e-MTBs and all types of speed pedelecs in the major European and US market.
With a diameter of 180mm, the unit is designed to remain discrete and indistinguishable from the disc brake side. The freewheel body fits seven to ten speed cassettes and has been engineered for maximum heat resistance and compatibility with both 650B and 29” wheels.
One of the most important technical elements is the drop-out interface to resist torque. Bafang engineers have developed a special drop-out design, which delivers ultra-robust torque support integrated with the thru-axle system. Brands can also design their own dropouts, using this standard to match their frames.
The other standout feature is the waterproof Smart Plug quick release cable connector. Traditionally, a stiff cable exits from the axle and must be routed along the chain stay to an external connector, so that the rear wheel can be removed from the frame to fix a puncture, or for servicing. The SmartPlug makes this simple for both dealers and consumers and works with either speed or torque sensor bottom brackets.
The unit will be available from Q1-2018 onwards.
