An improved apparatus is disclosed and preferably includes a bifurcated truck assembly that is interlockingly and removably attached to a sole plate, as well as a quick-change wheel and axle apparatus. At least in a two-wheeled version of the roller skate apparatus, the wheels preferably include a generally flat horizontal central portion on the ground-engaging wheel periphery in order to provide greater ease and stability in two-wheeled skating.
