The invention relates to a bicycle frame, in particular to a damping bicycle frame stable in structure. A vertical beam is arranged at the lower end of a saddle casing, a right-angle type strengthening and fixing beam is arranged at the lower end of each of the vertical beam and an oblique beam, a top bar is arranged between the strengthening and fixing beam and a front-fork casing, a connecting plate is arranged at the position, of the right-angle bend, of the strengthening and fixing beam, a rear-axle fork frame is of a half-arc shape, the end portion of the rear-axle fork frame and the middle lower side of the oblique beam are connected through a hinged shaft, the rear-axle fork frame penetrates the strengthening and fixing beam from two sides, and a damping spring is connected between the position of the half-arc bend and the connecting plate. The hinged point of the half-arc rear-axle fork frame and the oblique beam is taken as a pivot, vibration is possibly absorbed by deformation of the bicycle frame under the action of the damping spring, and safety and comfortableness of a bicycle are improved; the right-angle strengthening and fixing beam is arranged in the middle of the entire bicycle body and is taken as core to be connected with the bicycle body, so that stability of the whole bicycle body structure is strengthened.
