Bafang Hub Motor for E-MTB and Speed E-Bikes
SUZHOU, China –Bafang’s new H800 gear-drive rear hub motor, with 350 or 500 W output and a max torque of 55 Nm, features a modern MTB thru-axle design. Together with the Boost option it’s most suitable for sporty e-MTBs and all types of speed pedelecs.
With a diameter of just 180 mm, the motor is virtually invisible from the disc brake side as the rotor has a diameter of 203 mm. The freewheel body fits 7 to 10 speed cassettes. It has been engineered for maximum heat resistance, and compatible with both 650B and 29-inch wheels.
GrooveDO drop out
According to Bafang “two other unique features differentiate the new motor from other products on the market.” Bafang points to an important technical element; the drop-out interface to resist torque. Bafang’s engineers have developed a special drop-out design which delivers ultra-robust torque support, seamlessly integrated with the thru-axle system. OEM’s can also design their own dropouts, using this standard to match their frames.
A second important new feature is the waterproof Smart Plug quick release cable connector. Traditionally a rather stiff cable exits from the axle and must be routed along the chain stay to an external connector. This allows the rear wheel to be removed from the frame to fix a puncture, or for servicing. The SmartPlug makes this super-easy for both dealers and consumers.
The hub works with either speed or torque sensor in the bottom brackets, while many different display are available. The new H800 will be available from Q1-2018.
