AI Technical Summary
Traditional carbon fiber frames lack targeted reinforcement design in key stress areas, which makes it easy for longitudinal impact force, steering torque and load pressure to concentrate, resulting in deformation or cracking. Furthermore, the seat bar can easily damage components and pose a safety hazard to the rider when it slips off.
Multiple continuous triangular structures are formed by reinforced components to disperse the impact force of riding, and the impact force is absorbed by the damping spring and multi-stage elastic ball structure through the buffer components to avoid rigid collisions and improve overall stability and comfort.
It effectively resists bumps and impacts during riding and steering torque, reduces the risk of structural damage, and improves riding comfort and safety.
