A vehicle includes a frame, a front ground-engaging sphere, a rear ground-engaging sphere, and gripping portions for a rider to hold. The front sphere is rotatable about a first axis which is transverse and fixed relative to the frame and the rear sphere is rotatable about a plurality of axes. The vehicle also includes a support, which is connected pivotally to a rear portion of the frame. The rear sphere is connected to the support for rotation about a second axis which is transverse and fixed relative to the support. The support is pivotal with respect to the frame about a third axis which extends downwardly and longitudinally of the vehicle, such that the support is pivotable through a range of positions including a neutral position wherein the first and second axes are parallel. The vehicle further includes a resilient biasing mechanism configured to resiliently bias the support towards the neutral position.
