A freestyle board sports device is described. More specifically, a rotatable footplate system for attachment to a freestyle board sports device, such as a skateboard with wheels, is described. The rotatable footplate system comprises a footplate assembly that is attached to the wheels of the skateboard and freely rotates in both a clockwise and a counterclockwise direction from a neutral position with respect to a vertical axis of the skateboard when a turning force is applied to the footplate assembly and/or wheels. An alignment mechanism automatically returns the footplate assembly and wheels back to the neutral position via a shortest path when no turning force is applied. A locking mechanism either allows or prevents the footplate assembly from rotating. |
