Abstract A convertible wheel apparatus for a skating device including a pair of wheels, a pair of wheel supports, and a connector. Each wheel support engages a respective wheel and includes a pivotal member defining a pivotal axis with at least one pivotal axis of the pivotal members located at a measurable non-zero distance from a respective virtual axis. The connector is attached to one of the pivotal members of each wheel support and concurrently positions the pivotal members. Control of the orientation of the rotational planes of the wheels is achieved by positioning features attached to a base element or by a biasing mechanism. Various skate configurations can be obtained by a choice selection and combination of connectors and axis constraints that characterize the convertible wheel apparatus.
