A wheel apparatus 10 comprising a spherical wheel 12, wherein the spherical wheel is rotatably supported by a support member 14, and wherein the support member includes at least one spherical wheel contact member 16, the at least one spherical wheel contact member being moveable between a first position in which the at least one spherical wheel contact member is in contact with the spherical wheel, and a second position in which the at least one spherical wheel contact member is out of contact with the spherical wheel. There also may be a first and second bearing assembly 18a/b. The spherical wheel contact member may be a roller (figure 3 16a) and may be able to pivot. There may be a brake pad (figure 4 24) is arranged either side of the roller and preferably the roller may contact the spherical wheel before the brake pad as the roller is moved towards the first position.
