The invention relates to a telescopic folding bicycle which comprises a frame, a main beam tube, a front fork and a rear fork, the main beam tube comprises a first part and a second part which are connected in a sleeved mode, the front fork is connected with the first part, the rear fork is connected with the second part, the front fork is used for assembling a front wheel, and the rear fork is used for assembling a rear wheel; the first part can be switched between a first position stretching forwards and a second position retracting backwards relative to the second part, so that the telescopic folding bicycle is switched between an unfolded state and a folded state. As the main beam pipe comprises the first part and the second part which are mutually sleeved, when the telescopic folding bicycle is folded, the first part is operated to be switched from the first position to the second position relative to the second part to be folded, and when the first part is located at the second position relative to the first part, the size of the main beam pipe is small; therefore, the size of the whole telescopic folding bicycle is small.

    本发明涉及一种伸缩折叠自行车,包括:车架,包括主梁管、前叉及后叉,所述主梁管包括相互套接的第一部分与第二部分,所述前叉与所述第一部分相连,所述后叉与所述第二部分相连,所述前叉用于装配前车轮,所述后叉用于装配后车轮;所述第一部分能够相对于所述第二部分在向前伸展的第一位置与向后收缩的第二位置之间切换,以使得所述伸缩折叠自行车在展开状态与折叠状态之间切换。由于主梁管包括相互套接的第一部分与第二部分,则在折叠伸缩折叠自行车时,操作第一部分相对于第二部分从第一位置切换至第二位置折叠即可,在第一部分相对于第一部分处于第二位置时,主梁管的尺寸较小,从而使得整个伸缩折叠自行车的体积较小。
