A rear swing arm structure for an electric scooter includes a pedal rear portion, a telescopic shock-absorbing unit, two swing arm units, and connecting rods. The swing arm unit is pivotally connected to the pedal rear portion, with the first connecting rod linking the telescopic shock absorber and the second connecting rod connecting the swing arm unit and the first rod. When the rear wheel encounters vibration, the swing distance of the first connecting rod adjusts to match the rear wheel's movement. This automatic adjustment balances shock absorption and buffering, preventing the system from being too hard or soft. This design improves comfort, reduces tail swinging and slipping, and enhances grip during turns, resulting in smoother control and increased safety on various road surfaces.
