A roller board allowing the rider to slide laterally in a manner similar to a snowboard. The roller board is comprised of a platform having four fixed wheels, and two pivoting rollers positioned along the platform's longitudinal axis. The fixed wheels function similarly to conventional skateboard trucks. The pivoting rollers rotate to align themselves with the direction of force exerted on the platform. The pivoting rollers are spring biased to align themselves with the longitudinal axis of the platform. A height differential between the two types of rollers enables the rider to transfer weight from one type of roller to the other, alternating between the carving and sliding characteristics of a snowboard.
