The invention relates to a bicycle and in particular relates to a belt pulley bicycle with a joint rear shaft fork frame. The middle of the upper fork of the rear shaft fork frame is divided into three parts, namely an upper connecting part, a middle connecting block and a lower connecting part in the order from top to bottom; the angle of the section is relative to the direction of an angle of 45 degrees; a reinforcing connecting plug is welded at the fracture of the upper connecting part and the lower connecting part; the middle connecting block is fixedly connected with the reinforcing connecting plug of the upper connecting part and the lower connecting part by use of a screw perpendicular to the section. Due to the assembly and connection of the three parts, namely the fixed connection of the reinforcing connecting plug and the middle connecting block both connected with the upper connecting part and the reinforcing connecting plug connected with the lower connecting part by use of the screw perpendicular to the section, the process structure is beautiful and the strength of the body of the bicycle is improved.
