eSystems – Bafang’s New H730 Hub Motor Features GVT Auto-Shift
September 28, 2025 - Bafang’s innovative new H730 hub motor is equipped with its patented Gear Variable Transmission (GVT) technology that’s designed to redefine urban commuting.
The new H730 system integrates a 3-speed automatic gearbox that seamlessly adjusts gears based on riding speed, eliminating manual shifting while delivering smooth cycling.
Bafang’s torque sensor and controller work in tandem to analyze pedalling input in real time, dynamically adjusting power output to prevent “ghost pedalling”.
This synergy enables smooth acceleration up to 25kph and optimizes energy efficiency, making the H730 ideal for daily urban commutes. “Automatic shifting simplifies riding, especially in crowded cities where cyclists need to focus on safety, not gear levers,” emphasized Leo Wang, Bafang’s R&D Senior Manager.
By removing external components like gear cables, levers, and derailleurs, the H730 achieves a sleek, minimalist design while enhancing durability. Its weather-proof construction ensures reliable performance in harsh conditions, significantly reducing maintenance needs.
Since GVT’s first product, the H700 dual-speed hub motor that was introduced in 2022, over 40 global e-bike brands have adopted the technology across urban, cargo, touring, and fat-tire models.
“Automatic shifting simplifies riding, especially in crowded cities where cyclists need to focus on safety, not gear levers,” emphasized Leo Wang, Bafang’s R&D Senior Manager.
The series now includes motors ranging from 250W to 1000W, alongside the RG A510.D 5-speed gear hub, which supports loads up to 200Nm of torque, a critical advancement for high-powered e-cargo bikes.
“GVT has transformed shifting from a mechanical process into an intuitive experience, aligning rider and machine as one,” said Zou Bin, Bafang’s GVT Engineer.
Bafang’s shift toward platform-based innovation reflects its commitment to solving industry-wide challenges.
By integrating GVT into shared bikes and foldable models, Bafang is pushing design boundaries while extending the lifespan of e-bikes through reduced wear.
