Chinese manufacturer Bafang is a titan of the electrical bicycle motor field, and therefore news swirling all around the corporation commonly traits toward new motor announcements. But the most recent headline-grabbing solution unveiling from Bafang is not a motor at all, but alternatively an internally geared hub created to present automated shifting on both electric and non-electric powered bikes.
The new Bafang hub delivers three gear ratios and is capable to change among the gears automatically based mostly on the bike’s velocity.
The hub is made to in good shape a vast range of wheel diameters and therefore can have its cadence-centered shifting points modified to meet altering wheel measurements and bicycle demands.
As opposed to some internally geared hubs that weren’t originally intended for the substantial torque of electric powered motors, Bafang’s supplying is intended to face up to powerful motors pulling up to 80 Nm of torque.
Though that won’t be enough for some of Bafang’s most extraordinary motors that can output torque figures at two times that amount, it will include most of the company’s motor lineup as very well as just about all European mid-push motors like these made by Bosch and Brose.
The computerized shifting mother nature of the hub gets rid of the will need for a shifter cable or handlebar controls, simplifying the person interface and lessening cable muddle on a bicycle and its bars.
Bafang claims that the hub is built for compatibility with a broad vary of electric powered bikes from town and utility e-bikes to cargo electric powered bikes. Apparently, the business is also positioning the hub for use in non-electrical bikes as effectively, which would place it in level of competition with other important bicycle component producers these as Shimano.
The new internally geared hub is built to perform with either standard chain drives or alternative belt drives. Belts this sort of as these formulated by Gates Carbon Push are turning into an more and more well-liked possibility for mid- to substantial-tier electric powered bikes.
We experienced the possibility to tour Bafang’s manufacturing facility in 2019 and enjoy how the organization assembles its motors on its generation line. You can see that course of action in our online video tour of the Bafang manufacturing facility beneath.
We have in fact suspected for some time now that Bafang would get into the transmission game. It makes sense looking at that lots of of the company’s far more impressive motors have pushed the boundaries of existing bicycle drivetrains developed by OEMs these types of as Shimano.
This is not even Bafang’s very first transmission in a hub, even though it may possibly the company’s very first standalone model. Bafang has formerly generated hub motors with created-in automatic two-speed gearboxes, and some of that development work probably assisted direct the style and design of this new a few-velocity hub.
I’m a bit stunned we have not viewed Bafang innovate on the bigger electrical power conclusion of the transmission assortment, contemplating its highest electricity motors are commonly recognized to be especially harsh on primary bike components this sort of as chains and sprockets that are not developed to handle these significant electric power and torque stages.
Potentially these kinds of a transmission is continue to under enhancement even though, with this 80 Nm presenting staying an early launch just before its large brother hits the market.
