The H730 system automatically shifts gears approximately 100 times during a 20km commute, adapting to speed changes without rider input. This contrasts sharply with traditional derailleur systems, which demand constant attention.
Simplicity meets precision
"Automatic shifting simplifies riding, especially in crowded cities where cyclists need to focus on safety, not gear levers," emphasizes Leo Wang, R&D senior manager at Bafang.
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 mud, rain, or harsh conditions, significantly reducing maintenance needs.
Intelligent power delivery
The torque sensor and controller work in tandem to analyze pedaling input in real time, dynamically adjusting power output to prevent ‘ghost pedaling’ – a common frustration in single-speed e-bikes. This synergy enables smooth acceleration up to 25 km/h and optimizes energy efficiency, making the H730 ideal for daily urban commutes.
The motor’s high compatibility with e-bike designs allows manufacturers to create integrated, belt-driven systems that prioritize aesthetics and functionality.
A legacy of innovation
GVT marks the result of years of research and development by Bafang, following key milestones such as the introduction of the industry’s first external rotor hub motor in 2003 and the launch of the M400 mid-drive system in 2015. Since the debut of GVT’s first product, the H700 dual-speed hub motor, in 2022, more than 40 global e-bike brands have integrated the technology into a range of models, including urban, cargo, touring, and fat-tire bikes.
The design philosophy of GVT aims to simplify the operation, offering riders a new riding and shifting experience. This same experience can also be found from mid-drive systems paired with automatic shifting hubs, like the M210 mid-drive system combined with the RG A310.D 3-speed automatic gear hub.
Intuitive shifting experience
"GVT has transformed shifting from a mechanical process into an intuitive experience, aligning rider and machine as one," says Zou Bin, Bafang’s GVT engineer. 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.
Platform for the future
The shift toward platform-based innovation reflects its commitment to solving industry-wide challenges. By integrating GVT into shared bikes and foldable models, the company is pushing design boundaries while extending e-bike lifespans through reduced wear.
"GVT is more than a product – it’s a technological foundation," notes Wang. "We’re exploring new possibilities to further elevate the riding experience."
Global evolution
Since its founding in Suzhou in 2003, Bafang has driven global e-bike evolution, from powering the French postal service (La Poste) in 2008 to pioneering global market and complete drive solutions. "The GVT series stands as a testament to our mission: merging user-centric design with cutting-edge engineering to achieve true ‘rider-e-bike-in-one’ harmony," concludes Wang.
