A caster board, vigorboard or waveboard is a two-wheeled, human-powered land vehicle. Other names are J-board and RipStik (sometimes written ripstick or rip stick), both of which are derived from commercial brands.
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 each wheel can steer independently, and each caster has a steering axis that is tilted about 30° back from the vertical.
