Forget fiddling with derailleurs and gear levers mid-commute. Instead, Bafang wants to make urban e‑biking smoother than ever with its all-new H730 hub motor, featuring its patented GVT (Gear Variable Transmission) technology. The idea is to combine the advantages of internally geared hubs with Bafang’s own hub motors to create an internally geared hub motor.
We covered Bafang’s GVT technology after seeing it first-hand on a tour of the company’s headquarters in China. Now we’re getting a look at a new 3-speed version, which takes the original 2-speed concept even further.
Launched this summer, this new hub motor packs a 3‑speed automatic gearbox that shifts gears seamlessly based solely on riding speed – no rider input needed.
The benefits are immediate: durability, simplicity, and less maintenance. Without derailleurs, cables, or external shifters cluttering the setup, the H730 boasts a clean, minimalist rear-end design, not to mention the benefits of weatherproofing the transmission to handle rain, mud, and debris.
The 250W motor includes a torque sensor and smart controller to analyze riders’ pedal input in real time, suppressing pedal lag while delivering smooth acceleration up to 25 km/h (15.5 mph). It’s an ideal match for daily commuting, where energy efficiency and responsiveness matter. The speed limit fits European-regulation bikes, but it would make sense to see Bafang introduce a slightly faster 20 mph (32 km/h) version for the North American market.
That’s even more likely considering Bafang seems to be targeting broad compatibility, with the company highlighting how the H730 plays well with belt-drive systems and minimalist e‑bike frames.
The GVT system itself is the culmination of nearly two decades of innovation, Bafang explained. Since its introduction with the H700 motor in 2022, over 40 global e‑bike brands, covering everything from urban commuters to fat‑tire and cargo e-bikes, have adopted GVT-powered solutions.
Bafang seems to be positioning the GVT as the foundation of a platform, with the company seeing the H730 as a springboard for integration into shared‑bike fleets, folding bicycles, and e‑bike systems built to last. That’s a compelling narrative for urban mobility: fewer moving parts, smarter automation, and a ride experience tuned for simplicity and longevity.
Electrek’s Take
I love this solution because we’ve normally had to choose between an internally geared hub OR a hub motor, but not both. Getting an IGH normally meant shelling out for a more expensive mid-drive motor, but now it’s possible to get the benefits of both. An economical hub motor can keep prices more affordable, while the IGH means you don’t have the muss and fuss of a derailleur.
I wish the system also worked through the motor itself (i.e. could downshift the motor for more torque on hill climbs), but this is still great progress for the industry. And who knows, maybe Bafang has gear-shifting hub motors in development somewhere to give us the multi-ratio motors we want. Until then, this looks pretty cool.
