Abstract: A tow bar for attaching two bicycles in tandem arrangement consisting of a hollow rod, tube, or pipe having an attaching strap traversing the length of the interior of the rod or pipe, with the strap being secured to frame members of each bicycle via a friction clamp at each bicycle without the need for tools. Further, the tow bar consists of an assembly of four or more segments that have removeable couplings by which each such segment is attached to an adjacent segment, thereby facilitating ease of assemble and disassembly of the tow bar. Such segments, when disassembled, can be easily stored in a conventional bicycle pouch that can be attached to a frame member of the bicycle.
