AI Technical Summary
The existing electric bike frame has an unreasonable center of gravity distribution, which leads to unstable handling and a high risk of tipping over in complex road conditions, making it difficult to adapt to mountain and off-road riding.
The frame design features a hollow frame structure, with the battery and motor centrally located in the frame's central area. The battery compartment and motor compartment are formed by the separate connection of the U-shaped upper tube and the V-shaped lower tube and the fixing plate, and are equipped with shock absorbers to buffer vibrations.
It achieves a balanced center of gravity, improves stability and anti-rollover ability, enhances riding comfort, and is suitable for a variety of riding scenarios.
