Abstract
A skateboard is provided with trucks, each of which carries a plurality of wheels mounted in independent suspension. Longitudinally extending arms carry the wheel axles forwardly or rearwardly relative to a mounting which secures the arms in rotatable fashion to the trucks. The arms are resiliently biased by means of separate springs or torsion bars so that varying pressures across the skateboard platform alter the distance of the skateboard wheels from the underside of the platform and conversely roadway irregularities displace the skateboard wheels towards the platform independently one from another.
