[0002] When assembling an electric bicycle, it is necessary to configure the shock absorber. At this time, the shock absorber is generally welded in front of or below the center tube. The corresponding welding method can flexibly set the position of the shock absorber, but it causes the flexible adjustment of the shock absorber. The structure of the vibrating part is not compact and takes up a lot of space. In addition, the current welding configuration method and the welding process are cumbersome. After welding, the welding part must be sprayed, to ensure that the car body is in good condition, which affects the preparation efficiency of the entire vehicle. At the same time, the current welding method, the structural reliability of the shock absorber depends on the work level of the welding personnel and the fixed reliability. Shock absorber settings cannot be guaranteed.
