Bafang introduces a powerful rear hub motor for e-MTB and 
speed pedelec applications

Suzhou, PRC, August 16, 2017 – The Bafang 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 with Boost standard.
This makes the hub perfect for sporty e-MTBs and all types of speed pedelecs in the 
major European and US market.

With a diameter of just 180 mm, it’s virtually invisible from the disc brake side (rotor 
diameter 203 mm). The freewheel body fits 7 to 10 speed cassettes. It’s been 
engineered for maximum heat resistance, and compatible with both 650B and 29” 
wheels.

Two other unique features differentiate the new motor from other products on the 
market. 


GrooveDO™ - grooved drop out

One important technical element is the drop-out interface to resist torque. Bafang 
engineers have developed a special drop-out design which delivers ultra-robust torque 
support, seamlessly integrated with the thru-axle system.

  

Special grooved dropout design: Specially engineered dropout construction to absorb motor torque.


Brands can also design their own dropouts, using this standard to match their frames.


Bafang SmartPlug™

The other standout 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, so that the rear wheel can 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 bottom brackets, and many different 
display options are also available. Similarly, batteries of different types, f.e. the new, 
integrated F-series batteries from Bafang or from other manufacturers can be selected 
if required. 

The super-silent operation of this hub motor is particularly impressive, thanks to a 
specially-designed gear reduction system. It will be available from Q1-2018 on.
