Abstract: The invention provides a wheeled base for luggage, a golf club bag, dollies and the like, the base comprising an axle having a pair of spaced-apart primary transport wheels provided at opposite ends thereof and further comprising a pair of spaced-apart secondary transport wheels, wherein each of the secondary transport wheels is provided with an axle which can be extended telescopically from ends of the axle supporting the pair of primary transport wheels, the arrangement being such that each of the secondary wheels is displaceable between a first compact position adjacent to an outer side of one of the primary wheels and co-axial therewith, and a second position extended in a spaced-apart array relative to its initially-adjacent primary wheel to form a base with four mutually spaced-apart co-axial transport wheels.
