A caster board or vigorboard is a two-wheeled, human-powered land vehicle. It is somewhat like a snakeboard. Other names are waveboard and RipStik, both associated with commercial interests.
A caster board has two narrow platforms known as "decks" that are joined by a "torsion bar", which consists of a metal beam, usually coated by rubber, that houses a strong spring. One polyurethane wheel is mounted to each deck with a caster so that that each wheel can steer independently, and each caster has a steering axis that is tilted about 30° back from the vertical.
