Small-wheeled e-bikes are a growing sector globally, with both folding and compact bikes gaining ground in different markets. In the UK, 20"-wheeled compact city bikes are increasingly popular for their big bike ride feel, and folders are always in demand too. Motor giant Bafang are addressing that demand with two new motors specifically designed for short-hop bikes, which we'll no doubt start seeing on new bikes from later in the year.
G353 3-speed hub
This 220W powered rear motor with an integrated gear drive fits the narrower 120mm axle standard found on many folding bikes. It's disc brake only, and weighs in at just 2.4kg, which is a kilo less than many other popular hubs. The special cassette features a 9/13/17 tooth configuration activated by a short cage rear derailleur and 3–speed trigger shifter made by Sensah. The hub can be combined with either a speed or a torque sensor bottom bracket, and it's compatible with a range of Bafang displays and third party batteries
G351 singlespeed hub
Like its 3-speed sibling this single speed 220W rear hub motor is disc brake only and uses the same 120mm width. With a single 9 tooth cog it's even lighter at just 2.2 kg, making it one of the lightest geared hub motors in the market. Both hub motors feature quiet operation due to a special reduction system. The hubs are available in black or silver finishes.
