Bafang launch 3-speed automatic gear hub

Bafang has introduced an all-new 3-speed automatic, intelligent-acting, gear hub which removes the need for the rider to manually change gears.

The announcement highlights that, instead of shifting gears, Bafang has developed the new set up to shift according to the speed, in a quiet, discreet, and precise fashion, which happens automatically. This is made possible via an optional speed detection sensor, which replaces the traditional sensor installed on the chain stay, providing a very clean solution for mid-drive systems.

The 3-speed hub has precise shift points (25km or 32km) according to the wheel speed, thanks to Bafang‘s clutch mechanism. No matter if 20’’ or 24’’, for folding/concept bikes, or for bigger sizes such as 26’’or 28’’, the gear hub works seamlessly. Shift points are ideally matched (cadence calculated/based on a 38T/16T chain wheel), enabling riders to enjoy riding without need for gear shifting. This means less distraction on the road, increasing riding comfort and safety.

In terms of components, there is no need for an additional shifter and shift cable, resulting in lower maintenance requirements, easier servicing, and a high performance.

Weighing only 1.7kg, delivering 80Nm of torque, the hub is compatible with by both chain- and belt-driven motors. Plus, it can be used without any electric assistance at all on standard pedalling bicycles. This automatic gear hub is particularly suitable for e-trekking, e-city and e-cargo bikes (reduction ratios of 1:1, 1:1.36 and 1:1.65).

The e-bike motor manufacturer continues to expand its extensive product portfolio in the drive components segment, and as means to ‘real world’ test products, has recently unveiled its very own test track facility, which fully simulates various cycling scenarios from across the world, including many road surface types and cycling conditions.

Sustainably designed, the 8km-long test track is located in a 10,000 hectare industrial area (up to 60% forested) alongside a centrally located lake, with sections of the track featuring gradients between 10 and 15 degree, also enabling wet and dry surface testing.
