Abstract

The invention relates to a bicycle frame, in particular to a bicycle frame with an integrated bent upper beam. The bicycle frame comprises a front fork sleeve, a saddle sleeve, a center shaft sleeve and a rear shaft fork frame. The front fork sleeve is connected with the center shaft sleeve by an oblique beam, the integrated bent upper beam is arranged between the saddle sleeve and the front fork sleeve, the front section of a bent section of the integrated bent upper beam is fixedly connected with the middle section of the oblique beam, and the lower end of the rear shaft fork frame is fixedly connected with the center shaft sleeve. The bicycle frame has the advantages that the integrated bent upper beam is arranged between the saddle sleeve and the front fork sleeve, the front section of the bent section of the integrate bent upper beam is fixedly connected with the middle section of the oblique beam, and the lower end of the rear shaft fork frame is fixedly connected with the center shaft sleeve, so that a vertical beam for the saddle sleeve can be omitted, the rear shaft fork frame is connected with the center shaft sleeve, and an excellent integration effect of the bicycle frame can be realized; a tail frame and the rear shaft fork frame are of integrally connected structures, so that an integration effect of a bicycle can be improved, and the bicycle is firm in structure.

Description

technical field [0001] The invention relates to a bicycle frame, in particular to a bicycle frame with an integral curved upper beam. Background technique [0002] The vehicle frame of bicycle generally comprises the front fork sleeve that is used to install front fork in the prior art, is used to install the saddle bushing of saddle, is used to install the central shaft bushing of central shaft, front fork sleeve and saddle The sleeves are connected by the upper beam, the center shaft sleeve and the front fork sleeve are connected by the inclined beam, and the saddle sleeve and the center shaft sleeve are connected by the vertical beam, and it is also used to install the rear wheel One end of the rear axle yoke is used to install the rear axle, and the other end is fixedly connected with the center shaft sleeve. [0003] However, in the prior art, a beam is set up under the saddle sleeve and connected with the center shaft sleeve, and there is no overall effect between the...
