Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] See attached document Figure 1-6 An electric motorcycle includes an integral frame, a seat assembly on top of the integral frame, a front fork assembly, a front wheel, and handlebars at the front end, and also includes a rear wheel upper bracket 5, a rear wheel lower bracket 6, and a shock absorber spring assembly 2. The shock absorber spring assembly 2 is located at the integral frame and is connected to the front end of the rear wheel upper bracket 5. The rear ends of both the rear wheel upper bracket 5 and the rear wheel lower bracket 6 are connected to the rear wheel 4, and their front ends are open. A shock absorber linkage assembly is connected to the openings of the rear wheel upper bracket 5 and the rear wheel lower bracket 6. The shock absorber spring assembly 2 includes a spring shaft and a spring.

[0028] The shock absorber linkage assembly includes a horizontal linkage 9 and a vertical linkage 10. The horizontal linkage 9 is connected to the front end of the rear wheel bracket 5 via a horizontal linkage pivot 11, and the horizontal linkage 9 and the vertical linkage 10 are connected via a vertical linkage pivot 12.

[0029] The Z-shaped shock absorption system, formed by the shock absorber spring assembly 2 and the shock absorber linkage assembly, provides a comfortable shock absorption effect.

[0030] Both the upper rear wheel bracket 5 and the lower rear wheel bracket 6 are U-shaped. Figure 13 shows the connection point of the rear wheel 4 bracket, where the U-shaped openings of both the upper rear wheel bracket 5 and the lower rear wheel bracket 6 are connected to both sides of the rear wheel 4. The middle section of the upper rear wheel bracket 5 is a middle connecting plate 16, which is rotatably connected to the transverse connecting rod 9 via a transverse connecting rod pivot 11.
