In general, two person bicycles are complicated structures requiring substantial modification to the basic structure of the vehicle. A kit for converting a conventional bicycle into a two person vehicle includes a rear T-shaped crossbar for mounting on the top rear of a bicycle frame, the rear crossbar carrying a pair of seats on the outer free ends thereof; a front, generally U-shaped crossbar with a central bracket for mounting on the top end of the bicycle frame; fixed handlebars on one arm of the front crossbar, a rotatable shaft in the other arm of the front crossbar, a steering linkage interconnecting the shaft and the top end of the front fork carrying shank of the bicycle, handlebars on the top end of the shaft for rotating the latter to steer the bicycle, and an extra pedal and pedal crank arm connected to each existing pedal, so that each rider has a set of two pedals on each side of the bicycle frame.
