The invention discloses a bicycle lever-driven speed change system and a bicycle with the same, and belongs to the field of vehicles, the bicycle lever-driven speed change system is arranged depending on a bicycle frame of the bicycle and comprises flywheels symmetrically arranged on the left side and the right side of the bicycle frame respectively, at least two movable shafts, a speed change mechanism, a rotary bearing and an interactive lever, the flywheel is arranged on the side close to the bicycle frame and connected with the interaction lever through a movable shaft, a speed change mechanism and a rotating bearing are sequentially arranged between the flywheel and the interaction lever from the flywheel to the outside, and pedals are arranged on the interaction lever. Lever driving is adopted, the human motion law is met, and the driving efficiency is high. The speed change device is simple in structure and fast and simple in speed change; the bicycle frame is an integral bicycle frame, elastic deformation of materials is fully utilized to absorb impact during riding, and the buffering and damping effects are achieved.

    本发明公开了一种自行车杠杆驱动变速系统和具有该系统的自行车,属于交通工具领域,该自行车杠杆驱动变速系统依托自行车的车架设置,包括在车架左右两侧分别对称设置的飞轮、至少2个活动轴、变速机构、旋转轴承和交互杠杆,飞轮设置在靠近车架的一侧,并通过活动轴与交互杠杆连接,飞轮和交互杠杆之间自飞轮向外依次设置有变速机构和旋转轴承,交互杠杆上具有脚踏板,本发明的自行车杠杆驱动变速系统不容易出故障,即使损坏也方便维修更换,采用杠杆驱动,符合人体运动规律,驱动效率高;变速装置结构简单,变速快且简单;车架为整体车架,充分利用了材料的弹性形变来吸收骑行时的冲击,起到了缓冲、减震作用。
