The Chinese manufacturer Bafang is a big name in the field of bicycles and e-bikes. Now they have presented another exciting innovation. And it comes in the form of a hub gear with three gears, which shifts completely automatically and is thus intended to provide improved riding comfort.
Bafang 3-speed automatic presented
As the magazine Electrek reports, the new Bafang 3-speed automatic relies on a hub gear and switches independently, depending on the current speed, between the individual gears.
With the development above all a highest possible compatibility stood in the focus, because the new circuit can be used not only with normal bicycles and E-Bikes, but fits also to a large selection of wheel diameters. The shift points of the gearbox can be adjusted to the cadence and can be adapted to the specifics of the bike and to customer requirements.
Unlike most internally shifted hubs, the new Bafang system is also compatible with electric motors of e-bikes, provided they do not exceed a torque of 80 Newton meters.
This supports most of the manufacturer’s motors, as well as the main European mid-range e-bike drives. As an example, Electrek cites mid-range motors from Bosch and Brose. With a tare weight of 1.7 kg, the Bafang circuit is even relatively light. It should be suitable primarily, but not only, for e-trekking, e-city and e-cago bikes, the manufacturer promises in the press release.
Simple design, high comfort
The automatic shifting of the new Bafang 3-speed automatic transmission also requires no shift cable or handlebar unit, which is said to simplify the user interface and ensure less cable clutter.
At the same time, this should make cycling more comfortable. The hub gears are compatible with both chain and belt drives and can be used on normal bikes, which means that the company does not shy away from competing with other manufacturers such as Shimano.
Especially the low-maintenance belt drives such as Gates Carbon Drive, which is used for example in the Urtopia e-bike, have recently enjoyed growing popularity in the mid-range and high-end segment. It is not yet known when the Bafang 3-speed automatic for hub gears will be available and how high the price will ultimately be.
