Complaint
Main structure: A type of four-link system, such as the one used in GIANT's NRS frame. In this structure, the rear wheel is tilted backwards to absorb shock, and the shock absorber does not have a reverse slow travel. In the event of a collision, the shock absorber immediately pulls away from the chain guide bar after absorbing the shock, which can cause subsequent shaking.
Advantages: No shaking, even when riding in a standing posture, it is still stable.
Technology: There is no need for a rear shock absorber with a treadle platform, as this shock absorber system is already equipped with anti-shaking measures.
