A tensile type folding bicycle frame belongs to the field of folding bicycles. The problem that the existing folding bicycle still occupies a large space after being folded is solved. The tensile type folding bicycle frame comprises a front fork, a connecting rod, a bicycle seat and a rear fork, wherein the front fork, close to a branch fork, is in rotating connection with one end of the connecting rod in the circumferential direction of the front fork and in the opening and closing directions of the front fork and the connecting rod; the parts, above the rotating connection part of the front fork and the connecting rod, of the front fork and the connecting rod are further connected through a pull rope A, and the pull rope A is in rotating connection with the front fork in the circumferential direction of the front fork; a transverse support plate is arranged between the front fork and the connecting rod; and the other end of the connecting rod is in rotating connection with the bicycle seat in the opening and closing directions of the connecting rod and the bicycle seat, the bicycle seat is further in rotating connection with the upper end of the rear fork in the opening and closing directions of the bicycle seat and the rear fork, the connecting rod is also connected with the rear fork through a pull rope B, and a triangular structure is formed by the connecting rod, the rear fork and the pull rope B when the pull rope B is in a tensioned state. The tensile type folding bicycle frame is used for a folding bicycle.
