Vanpowers Bike, an e-bike startup formed earlier in 2022, is set to launch the world’s first e-bike with an assembled frame. The frame of this unique e-bike uses an ancient Chinese mortise and tenon structure to provide “a superior riding experience and safety,” according to Vanpowers.

According to Vanpowers, most one-piece frames on the market are primarily heated to extreme temperatures after welding, with manual shape adjustment and polishing. However, if this technique is repeated more than twice, the frame will become extremely fragile and will have to be discarded.

Vanpowers has come up with a new solution to the problem of the instability and fragility of a one-piece frame, which it claims is the first of its kind. The new e-bike, dubbed City Vanture, has an assembled frame that integrates ancient Chinese mortise and tenon construction methods with current industrial technology. As a result, the frame is said to be able to withstand heavy loads while reducing the frame’s deviation from symmetry and maintaining its strength. This results in better security and stability.

Going into more detail, Vanpowers says that the City Vanture’s mortise and tenon construction manages and lowers centerline tolerances. It can also reduce the number of frames that are discarded in the manufacturing process, which is good for the environment. Plus, when routine maintenance is needed, the battery can be safely disassembled and rebuilt, making it easier and more affordable to keep the bike in service longer.

The City Vanture is equipped with a brushless hub motor. The 350W motor, sensor and controller are all integrated into a single unit, which greatly facilitates disassembly and assembly. The electric motor, which uses a Gates belt drive instead of a traditional chain, drives the two-wheeler to a top speed of 25 miles per hour. Gates belt drive systems are known for their long life and quieter operation than traditional chain drives. Plus, the belt is much lighter than a traditional chain, which translates to smoother power and a claimed life of over 20,000 miles.

As for the battery, the City Vanture sips juice from a 36V 7Ah LG3500 lithium battery. The battery, according to Vanpowers, can deliver 50 miles of range in just two hours of charging. Installing a battery extender is also an option, and Vanpowers claims this will extend the City Vanture’s range to 80 miles.
