The invention relates to a bicycle frame, in particular to a show bicycle frame in a stable structure. An upper beam penetrates a front fork sleeve and a vertical beam, the upper beam penetrates the vertical beam to extend to the upper end of a rear shaft fork support, the lower end of the rear shaft fork support is connected to a middle shaft sleeve, the upper end is fixedly connected to two sides of the front side of the upper beam adjacent to the connection of the upper beam and vertical beam, the shape of the upper beam is consistent to that of the curve of the upper end of the rear shaft fork support after extending out of the vertical beam, and the upper beam extends to the rear end to integrate with the upper end of the rear shaft fork support in shapes and is connected to two sides of the upper end of the rear shaft fork support structurally. Thus, the bicycle is fine in integral effect, high in impact resistance and stable in structure, and the bicycle is prevented from deforming during shows.
