Abstract
A dual recumbent vehicle is provided which includes a pair of recumbent bicycles interconnected in a side-by-side relationship. Each bicycle has an operator controlled steering assembly, an operator controlled drive assembly, and a recumbent seat operatively connected to a frame structure. Each of these bicycles is further connected by cross-braces for operatively connecting the bicycles in a side-by-side relationship, and a steering coupler for coupling the steering assemblies of each of the bicycles so that they operate in unison. A preferred dual recumbent vehicle can be steered by any rider on the vehicle, and varying proportions of power may be provided by different riders. Further, a preferred dual recumbent vehicle is easy to assemble and disassemble into independently operatable bicycles, and is capable of being stored in an upright position in order to decrease the space required for such storage.
