Abstract

The invention relates to a bicycle frame and in particular relates to a dual-lug performing bicycle frame. The dual-lug performing bicycle frame comprises a head tube, an upper tube and a lower tube both connected with the head tube, a vertical tube connected with the upper tube, a rear shaft fork connected with the vertical tube, and a five-way joint connected with the tail end of the lower tube, the vertical tube and the lower end of the rear shaft fork; two holes are formed on the two sides of the head tube, and the hole on the upper side is a locking hole, while the hole on the lower side is a positioning hole; L-shaped tie wire holders are mounted on the two sides of the head tube; a projecting positioning lug is arranged on the vertical section of each L-shaped tie wire holder, a fastening hole corresponding to the locking hole is formed in the upper end of the positioning lug, the positioning lug is inserted into the positioning hole and locked and fixed by use of a screw connected with the locking hole and the locking hole; a tie wire connecting hole is formed in the horizontal vertical section of each L-shaped tie wire holder. As the L-shaped tie wire holders mounted on the two sides of the head tube are utilized to take the place of tie wire fixing bowls and the positioning lugs are inserted into the positioning hole and locked and fixed by use of the screw connected with the locking hole and the locking hole, the assembly and the structure are relatively simple and the shape is beautiful and elegant.
