In the wave of green travel, electric bicycles have gained widespread recognition for their environmentally friendly and convenient features. However, for a long time, there has been little breakthrough in the transmission systems of electric bicycles, with most still relying on the manual shifting methods of traditional bicycles. Now, the GVT technology introduced by Bafang, especially the new G500A 5-speed gear hub, is revolutionizing this status quo and bringing a revolutionary upgrade to the shifting experience of electric bicycles.
Bafang’s Gearless Variable Transmission (GVT) technology is an internal transmission system specifically designed for electric bicycles. It replaces the traditional manual transmission system with an automatic shifting function, greatly simplifying the riding process. Gary Xu, the director of the R&D department, pointed out that the original intention of the GVT technology design is to reduce the frequency and cost of maintenance, eliminating the need for shift levers or cables, thereby reducing the need for replacement. This system features a wireless design, non-grip, and in terms of material selection, Bafang places special emphasis on the use of renewable, recyclable, and biodegradable materials to reduce reliance on non-renewable resources.
The newly launched G500A by Bafang is an automatic 5-speed gear hub that is part of the GVT technology series. This system, through automatic shifting, allows riders to focus more on the road and riding performance, rather than on cumbersome shifting operations. Automatic shifting ensures that the bicycle always travels in the most suitable gear for the current environment, providing a smoother, safer, and more enjoyable riding experience.
The GVT technology has three major core advantages:
- Intelligent Automatic Shifting: Automatically adjusts gears based on wheel speed, offering a seamless riding experience without the need for manual operation.
- Highly Integrated Design: As demonstrated in the H700 model, the gearbox is integrated with the hub motor, streamlining the design and reducing installation complexity.
- Handle-free and Wireless Design: Eliminates traditional shifting components, giving the electric bicycle a cleaner and smoother appearance, and reducing maintenance requirements due to harsh weather or external wear.
The G500A is a robust and durable 5-speed gear hub capable of withstanding high loads up to 200 Newton meters, making it highly suitable for high-power electric bicycles. Compared to traditional gear systems, it is more durable and not prone to damage even under high power output. After undergoing continuous 800-hour 100 Newton meter load testing and 10,000 cycle impact testing for each gear, the G500A has proven its longevity. GVT technology ensures smooth gear transitions, enhancing the riding experience.
The introduction of Bafang’s GVT technology and the G500A gear hub is not just a technological leap but also heralds a revolutionary upgrade in the transmission systems of the electric bicycle industry. The application of this innovative technology signifies that electric bicycles are advancing towards a new era that is smarter, more convenient, and more eco-friendly.
