A folded bicycle frame comprising a single and continuous sheet of metal is disclosed. The bicycle frame is formed by cutting the sheet of metal to form a boundary, hydroforming the sheet of metal to create a profile comprising indentations and protrusions along the sheet of metal, and then folding the molded sheet essentially along its axis of symmetry, such that the symmetrical parts of the sheet are positioned next to each other to form the frame with a hollow interior. Holes are precut in the frame so that other bicycle parts may be attached to the frame. The frame is produced without the need for any welding or connecting of individual parts. Thus, it is stronger than conventional bicycle frames which are weaker at such welded connections of their parts. A method for making the folded frame is also disclosed.
