    The present invention relates to a bicycle frame, wherein a frame surface of a bicycle is protected and components of the frame are assembled to be coupled. Stainless plate materials are packed to form a bicycle frame on an outer circumferential surface of a high-strength plastic pipe or bamboo. An H1-coupling member and an H2-coupling member are formed in a head tube. In addition, a curved surface coupling member including a first B1-coupling member, a B2-coupling member, and a B3-coupling member is formed on an outer circumferential surface of a bottom bracket shell. A S1-coupling member and a S2-coupling member are formed at an upper side of a sheet tube and a lower coupling member is formed at a lower side thereof to be embedded into the B2-coupling member of the bottom bracket shell. A chain stay is assembled to be coupled to the B3-coupling member of the bottom bracket shell while a sheet stay is formed between a wheel fixing member formed at a tail unit of the chain stay and the S2-coupling member of the sheet tube. A head member and a tail member are formed at both ends of a top tube while being assembled and coupled to the H1-coupling member of the head tube and the S1-coupling member of the sheet tube. In addition, a head member and a tail member are formed at both ends of the bottom tube while being assembled and coupled to the H2-coupling member of the head tube and the B1-coupling member of the bottom bracket shell.
