The invention discloses a three-folding bicycle with an adjustable damping function, and relates to the technical field of bicycles. The bicycle comprises an upper pipe and a head pipe, one sides of the two adjacent ends of the upper pipe and the head pipe are rotationally connected through a hinge, the other sides of the two adjacent ends of the upper pipe and the head pipe are connected through a screw, one end of the surface of the head pipe penetrates through and is rotationally connected with a vertical handle through a bearing sleeve, the lower end of the vertical handle is fixedly connected with a front fork, and a front wheel is installed in the front fork. The upper end of the vertical handle penetrates through and is slidably connected with a handle. The main seat tube can be locked in the auxiliary seat tube by screwing down the seat tube bundle on the auxiliary seat tube, so that the effect of limiting the damping spring can be achieved, the damping effect of the bicycle is reduced, the bicycle can be conveniently driven on a flat road surface, the damping effect of the damping spring can be achieved by loosening the seat tube bundle on the auxiliary seat tube during driving, and the bicycle is convenient to use. The bicycle can conveniently run on the bumpy road surface.

    本发明公开了一种减震可调的三折叠自行车,涉及自行车技术领域。本发明包括上管和头管,上管和头管的相邻两端的一侧通过合页转动连接,上管和头管的相邻两端的另一侧通过螺丝连接,头管的表面一端贯穿并通过轴承套转动连接有立把,立把的下端固定连接有前叉,前叉的内部安装有前轮,立把的上端贯穿并滑动连接有把手。本发明通过拧紧副座管上的座管束即可让主座管锁紧在副座管内,以此可以达到让减震弹簧限位的效果,降低了自行车的减震效果,方便在平整的路面上行驶,通过松开副座管上的座管束即可达到让减震弹簧在行驶时有减震的效果,方便在颠簸不平的路面上行驶。
