A vehicle 2 comprises a frame 8, a front ground-engaging sphere 4, a rear ground-engaging sphere 6, and gripping portions 18 for a rider to hold. The front sphere 4 is rotatable about a first axis which is transverse and fixed relative to the frame 8. The vehicle 2 also comprises a support 16, which is connected pivotally to a rear portion of the frame 8. The rear sphere 6 is connected to the support 16 for rotation about a second axis which is transverse and fixed relative to the support 16. The support 16 is pivotal with respect to the frame 8 about a third axis which extends downwardly and longitudinally of the vehicle 2, such that the support 16 is pivotable through a range of positions including a neutral position wherein the first and second axes are parallel. The vehicle 2 further comprises a resilient biasing mechanism 22 configured to resiliently bias the support 16 towards the neutral position. Supports 14, 16 of the ground engaging spheres 4, 6 may be part-spherical shells.
