The invention relates to a folded bicycle frame which comprises a front fork stand pipe, a beam assembly, a rear wheel bracket assembly, a bicycle seat assembly, a cross bar assembly arranged on the front fork assembly, and a driving and transmission assembly, wherein a front fork assembly is arranged on a front wheel assembly; the rear wheel bracket assembly is arranged on a rear wheel assembly; the beam assembly is arranged between the front fork assembly and the rear wheel bracket assembly; the bicycle seat assembly is arranged on the rear wheel bracket assembly. The folded bicycle frame has the following advantages: as multiple X-shaped telescopic mechanisms and a quick-locking device are arranged, folding after quick-locking and locking after unfolding of the bicycle frame are realized, and the bicycle frame after being folded is small in size, so that the bicycle is small in size, light in weight and easy to carry.
