The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure, a wheel chassis, a wheel support, at least two wheels, and mechanisms which position the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The positioning mechanisms include tie rods, yokes, gear sets, and externally mounted rods or panels. A post on the bottom of the enclosure may include a threaded portion which is engaged by a nut to rotationally secure the position of the wheel chassis, or the post may include a portion of enlarged diameter supporting a spring which biases the wheel chassis into the post. A brake is provided to allow the user to slow or stop the skate in a controlled manner. An alternative embodiment involves a pair of yoke-chassis which both position and align the wheels.
