The H400 is a Bafang front hub motor positioned for eCity bikes. Bafang lists it as Bafang H400 36V 250W Front Hub Motor in its OEM catalogue and 2027 workbook, which are the sources for every figure on this page.
Bafang notes that its torque figures are “peak locked” values that can be reconfigured for an application and battery, so the torque you get depends on the controller set-up. At 2.4 kg and 250W it suits EU pedelec city bikes, and it is one of the few Bafang hubs listed for V-brakes as well as disc brakes.
This is an OEM motor sold bare (no rim or kit parts); confirm wheel size, cable length/connector and freewheel or sprocket before ordering.
