The seam (108) is formed by the connection of a first frame part (106a) and a second frame part (106b) connected to each other. The at least one housing (102a, 102b) and member (104a, 104b) may be different in size and shape but their function is to withstand forces in the longitudinal direction of the seam (108).

[0043] In this view of the embodiment a first housing (102a) comprises a protrusion from the frame (106a, 106b), which may be manufactured as part of the frame parts (106a, 106b) or attached thereto. A first housing (102a) is formed to the first and second frame parts (106a, 106b) coincidentally such that they are cross-sectionally aligned when the two frame parts (106a, 106b) are joined together. A first member (104a), which in this embodiment cylindrical and solid, is situated in the first housing (102a) adjacent to a part of the seam (108) and interlocked by the coincident first housings (102a) or by the connection to a frame part (106a, 106b) inner wall and insertion into the first housing (102a). The function of the at least one first housing (102a) and first member (104a) is to reinforce the frame. The first member (104a) of this kind may be a dowel, pin, rod, or the like.

[0044] As depicted, the first housing (102a) and the first member (104a) are preferably situated inside the bicycle frame when the frame parts (106a, 106b) are joined. The first housing (102a) and the first member (104a) are preferably connected to the inner surface or manufactured to be a part of the frame parts (106a, 106b) inner walls. However, the first member (104) may also be not connected to the inner surface or manufactured to be a part of the frame parts (106a, 106b) inner walls but be inserted into the coincident two first housings (102a) before the frame parts (106a, 106b) are adjoined. A second housing (102b) is formed as a cylindrical recess or cutaway to at least one of the first and second frame parts (106a, 106b), which may be manufactured as part of the frame parts (106a, 106b).
