The invention discloses a foldable bicycle and an electric bicycle frame, which comprises a girder and a rear fork, the girder and the rear fork are connected through a bearing and a rotating shaft, fixing holes A are formed in the two sides of the girder, the girder is connected to the upper portion of a hinge part through the fixing holes A, a fixing hole B is formed in the lower portion of the hinge part, and the rear fork is connected to the rear fork through a bearing. The rear fork is connected to the upper portion of a shock absorber through the fixing hole B. The lower portion of the shock absorber is connected to the rear fork through the fixing hole C. The two ends of the rear fork are each provided with an end cover. The foldable bicycle and the electric bicycle frame are simple in structure. The whole product adopts a one-shaft multi-purpose mode, the problem that a pedal shaft and a folding shaft can be shared is solved, therefore, frame assemblies are reduced, the weight of the whole bicycle is reduced, the whole bicycle is simpler, folding is more convenient, the manufacturing cost is low, and the folding bicycle can be used for folding bicycles and electric bicycles.
