The invention discloses a damping variable-speed power bicycle. The damping variable-speed power bicycle comprises a front wheel, a rear wheel and a bicycle body framework, an auxiliary power unit, a pedal driving unit, a saddle unit and a handlebar unit are arranged on the bicycle body framework; the saddle unit is provided with an insertion pipe, a locking sleeve, a spring and an air valve, a positioning protruding strip and a pressing plate are arranged on the outer side face of the insertion pipe, a guide groove is formed in the inner surface of a vertical pipe of the bicycle body framework, an annular groove is formed in the end face of the vertical pipe, a plurality of vent holes are formed in the vertical pipe, and the air valve is arranged on the vertical pipe. One end of the spring is arranged in the annular groove of the vertical pipe, the other end of the spring is arranged on the pressing plate, the inserting pipe is inserted into the vertical pipe, and the locking sleeve is sleeved on the pressing plate of the inserting pipe and is in threaded connection with the vertical pipe. The spring is arranged between the inserting pipe of the saddle and the vertical pipe of the bicycle body framework, the damping effect is achieved, the air cavity is formed by the inserting pipe and the vertical pipe, damping and shaking relieving are further achieved through the multiple vent holes and the air valve, and therefore the riding comfort is improved.

    本发明公开了一种减震变速的动力自行车,包括:包括:前轮、后轮以及车身骨架;车身骨架上设有辅助动力单元、脚踏驱动单元、车座单元以及车把单元;车座单元具有插管、锁紧套管、弹簧以及气阀,插管的外侧面设有定位凸条与压板,车身骨架的立管内表面设有导向槽,立管的端面设有环形槽,立管上设有多个通气孔,气阀设置在立管上;弹簧一端置于立管的环形槽中,另一端置于压板处,插管插于立管中,锁紧套管套设于插管的压板上与立管螺纹连接。本发明在车座的插管与车身骨架的立管之间设置了弹簧,起到减震的效果,并且插管与立管形成气腔,通过多个通气孔与气阀来进一步减震和减缓晃动,从而提升骑行的舒适感。
