October 29, 2024 - Earlier this year, Bafang introduced its innovative Gear Variable Transmission (GVT) technology platform along with its new G500A, an internal 5-speed automatic shift hub designed for high-powered e-fat bikes.

The new GVT system offers precise automatic shifting mechanisms and advanced transmission control, creating seamless and smooth gear changes.

Debuting at the 2024 China Cycle Show, the G500A automatic hub is belt drive–friendly and according to Bafang reduces common maintenance issues and durability concerns in shift systems, thus extending the overall lifespan of e-bikes.

Designed to effectively tackle challenging terrain, including snow and sand, the G500A can withstand torque ratings of up to 200Nm to significantly reduce the impact and possible damage to the chain and freewheel caused by high torque. It can also support higher speeds up to 45kph and 60kph.

Available with 175mm and 190mm dropout options, Bafang’s rigorous testing standards claim that each of the five gears in the G500A undergoes at least 10,000 impact tests, ensuring durability and rider confidence.

“Over the past three years, we have launched the automatic hub motor and the automatic gear hub series, both of which have received positive feedback from various markets,” commented Zou Bin, the chief engineer of the Bafang GVT system.

In the industry, the shifting performance of high-power eBikes has always been a hot topic. Due to the high output power, traditional external shifting systems face challenges with increased risk of damage. To address this, Bafang has introduced the GVT automatic shifting hub motor series including the H700, H710 and H720, covering power ranges from 250W to 1000W.

“Over 40 e-bike brands globally, including Dutch iMove and France’s Eovolt, have integrated our GVT products across urban, touring, cargo, and fat e-bike categories,” said Yingzhe Wang, Bafang’s head of R&D. “Without the need for shifting cables or external cassettes, you’ll find more folding bikes and urban shared bikes equipped with GVT series products. Looking ahead, we will continue to explore more possibilities on this platform.”
