[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] As shown in the accompanying drawings, the utility model relates to a spinning bike with elastic buffer, in which a spring device is added to a ground-contacting tube, and the buffer strength of the device can be adjusted according to the weight of different users. Specifically, the dynamic bicycle with elastic buffering described in the utility model comprises a dynamic bicycle body 6, which is installed on a fixed bracket 7. A machine ground pipe 1 is fixed to both left and right ends of the rear side of the fixed bracket 7. An inner tube 8 is arranged inside the machine ground pipe 1. An annular plate 9 is sleeved and fixed on the outer periphery of the top end of the inner tube 8, and is fixed to the inner wall of the machine ground pipe 1 through the annular plate 9. A bolt connecting plate 10 is fixed to the bottom of the inner tube 8. A bolt hole 11 is opened on the bolt connecting plate 10. A strong spring 2 is arranged inside the machine ground pipe 1. The top of the strong spring 2 is sleeved on the outer periphery of the inner tube 8. An adjusting bolt 3 is installed under the strong spring 2.
