DETAILED DESCRIPTION

[0015] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0016] Please refer to Figure 1 , Figure 1 Schematic diagram of a fast-shifting bicycle with a high-pressure resistant rim according to an embodiment of the present application. As shown in the figure, a fast-shifting bicycle with a high-pressure resistant rim is characterized in that it comprises: a hub 10, a rim 20, a connecting tube 30 is provided on both sides of the hub 10, a shockproof part 31 is provided on the connecting tube 30, and a fixing plate 40 is provided on the top of the connecting tube 30; a spoke group 50 is arranged between the hub 10 and the rim 20; the spoke group 50 includes three groups of spokes 51, the spokes 51 are rectangular, the width of the spokes 51 gradually increases from the inside to the outside, and an arc-shaped stepped reinforcement plate group 60 is provided on the three groups of spokes 51; a protective plate 70 is arranged on the outside of the spoke group 50, a trapezoidal weight-reducing hole 71 is provided in the middle of the protective plate 70, a circular weight-reducing hole group 72 surrounding clockwise is provided on the outside of the trapezoidal weight-reducing hole 71, and an arc-shaped reinforcement plate 73 protruding outward is provided on the upper side of the trapezoidal weight-reducing hole 71.
