A foot propelled vehicle comprises a front housing in which a first rotatable ground engaging sphere is mounted by bearings for rotation about a transverse axis and a rear housing in which a second rotatable ground engaging sphere is mounted by bearings for rotation about three orthogonal axes. The front housing is longitudinally spaced from and connected rigidly to the rear housing. A seat is situated between the first and second housings and positioned so that a riders feet can contact the ground to propel the vehicle. A handle is mounted on the front housing for the user to hold whilst riding and steering the vehicle. Lateral stabilizers may be provided. In some embodiments both spheres may be mounted for rotation about three orthogonal axes.
