ABSTRACT:
A three-wheeled vehicle having no driving connection to the wheels is powered by side-to-side forces applied by the operator to a pair of foot boards, each of which has a castered rear wheel having a pivot axis that is inclined with respect to the vertical. The forward ends of the foot boards are connected to a vertical steering head supporting a single front wheel. In one embodiment, the distance between the foot boards may be varied to suit riders of different sizes by changing the effective length of a crossmember rigidly interconnecting the footboards.
