Abstract: A vehicle (1) comprises a frame (17); a front ground engaging sphere (2) which is rotatable about a first axis which is transverse and fixed relative to the frame (17); a rear ground engaging sphere (3) which is rotatable about a plurality of axes, and gripping portions (11) which are provided towards the front of the vehicle (1), for a rider to hold. A support member (25) is connected pivotally to a rear portion of the frame (17) and projects longitudinally of the vehicle (1) and downwardly from the point of connection to the frame (17) to a remote part of the support member (25). The rear sphere (3) is connected to the remote part of the support member (25) for rotation about a second axis which is transverse and fixed relative to the support member (25). The support member (25) is pivotal with respect to the frame (17) about a third axis which extends downwardly and longitudinally of the vehicle (1).

Abstract: A bicycle having rotatable drive member in the form of a hollow drum (22) with pedals (48, 49). Each pedal is mounted in a foldable manner to a crank arm (24, 25) which in turn is mounted to the drum (22) by a pivoting mechanism (26, 27) allowing the pedals to be moved between an operative configuration in which each pedal projects outwardly from the drum (22), and an inoperative configuration in which each pedal (48, 49) and each crank arm (24, 25) is contained within the interior of the drum (22). The bicycle can thus be used as a training aid without the use of pedals, or in a conventional manner.

Abstract: 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 rider's 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.
