Recognized as a winner of the German Design Award 2026, the Bafang H730 represents a breakthrough in eBike drive systems. As eBikes become essential to daily mobility across Europe, this 3-speed automatic shifting hub system meets the increasing riders’ demands with an innovative GVT (Gear Variable Transmission) technology that blends seamless integration, minimal maintenance, and all-weather reliability.

- Smooth shifting for comfortable pedaling
The H730 automatically shifts at two specific speed points, seamlessly cycling through its 0.76, 1.0, and 1.31 gear ratios to deliver the right support at the right time. Closely-spaced gear ratios ensure seamless transitions between stages, maintaining a natural and continuous pedaling feel, effectively eliminating both “ghost pedaling” and "labored pedaling".
- Low gear (0.76): Delivers effortless starts and confident uphill climbing.
- Middle gear (1.0): Acts as a direct drive for smooth, efficient power transfer on flat terrain.
- High gear (1.31): Maintains a natural, comfortable pedaling cadence at higher speeds.
- Quiet motor for a Tranquil Journey
Advanced electromagnetic design, composite materials, and precision balancing work in harmony to ensure near-silent operation. The H730 lets the rider enjoy the surroundings without mechanical distraction.
- Low Maintenance for Effortless Lifestyles
The fully enclosed automatic transmission eliminates the need for external derailleurs, gear cables, and shifter. This integrated design protects the core mechanics from rain, dust, and winter road salt, offering outstanding reliability and drastically reducing maintenance while enhancing the bike's clean aesthetic.

Engineering Breakthrough
Building on the success of the 2-speed H700 from the Bafang GVT series, and refined with insights from real-world riding in hilly terrain, the Bafang H730 was developed to conquer diverse urban and countryside landscapes. Adding a third gear, however, presented a significant engineering challenge.
On paper, the addition of a single gear introduced complex spatial constraints in the development phase. The initial theoretical design resulted in a 160mm rear fork width, which presented challenges for both aesthetics and frame compatibility. The engineering team meticulously re-evaluated every millimeter of the motor and shifting structure. Through rigorous testing and new manufacturing processes, the design was successfully optimized to a sleek 148mm width—achieving a perfect balance of performance, form, and fit.

As the German Design Award jury particularly noted: "Automatic gear shifting that integrates seamlessly into everyday riding distinguishes the 'H730 Automatic Gear Hub Motor’. The clear, low-maintenance construction and consistent integration of technology ensure a distinctive, timeless user experience. The elegant combination of comfort and functionality is particularly impressive, making this product exemplary for outstanding technical design in this field."
