    • A bicycle frame (10) having a rear passive suspension system configured to elastically deflect predominantly in only the vertical direction under normal cycling loads so as to better isolate the rider from road-surface irregularities and roughness, while simultaneously maintaining or improving rigidity in other directions so as to preserve or improve handling. The frame (10) has a pair of upper chain stays (18) that control the rear wheel motion rigidly in five of the six degrees of freedom with stiffness comparable to existing road, cyclocross, hybrid, city, or hardtail mountain bicycle designs, while simultaneously allowing deflection of the tubular members and a significant amount of vertical movement of the rear wheel for ride compliance in order to improve comfort, handling, and safety.
    • 一种具有后被动悬挂系统的自行车车架(10),其构造成在正常循环载荷下主要在垂直方向上弹性偏转,以便更好地将车手与路面不平整度和粗糙度隔离,同时保持或改善其他方向的刚性 以保持或改善处理。 框架(10)具有一对上链支架(18),其以六个自由度中的五个刚性地控制后轮运动,刚度与现有的道路,自行车,混合动力,城市或硬尾山地自行车设计相当,同时 同时允许管状构件的偏转和后轮的大量垂直运动用于骑行顺从性,以便改善舒适性,操纵性和安全性。
