Abstract: A roller board including a board and two or more downwardly-disposed roller assemblies mounted on the board. Each roller assembly has an annular retaining collar with a spherical recess, a plurality of bearings seated within the recess, and a spherical roller ball rotatably seated in the recess in contact with the bearings. A stabilizer assembly is mounted between the roller assemblies to give lateral stability, and a false axle is provided in each of the roller assemblies for imparting increased friction upon contact with the roller ball. The false axle imparts a higher coefficient of friction on hard cornering, thereby simulating “carving” or digging in the edges of a snow board. The foregoing features combine to exactly simulate the sensation of using a snow board on snow.
