The invention relates to the field of machinery, in particular to a frame. The invention provides a multipurpose electric power-assisted bicycle frame which comprises a frame body, and the frame body comprises a front wheel, a front fork, a vertical rod, a transversely-arranged fixing rod, a connecting rod, a first shock absorber, a rear fork and a rear wheel. The rear fork comprises a first bent part, a second bent part and two straight rods, and the rear wheel is arranged between the two straight rods; the front portion of the first shock absorber is fixed to the middle of the connecting rod, and the rear part of the first shock absorber is fixed to the rear part of the second bent part. Through the design, the multipurpose electric power-assisted bicycle frame is simple in structure and convenient to use, an original rear fork structure is improved, the situation that a shock absorber cannot be installed on a small frame is avoided through cooperative work of the connecting rod, the first rotating shaft, the rear fork, the first shock absorber and other components, the shock absorption effect of the frame is improved, and thus the frame can achieve better stability, comfort and safety.
