Abstract
A twist vehicle includes a vehicle frame, a steering unit, a twisting unit and a connecting member in which when subsequent clockwise and anti-clockwise movements are imparted to the steering unit, the movements are then transferred to the twisting unit, causing the twisting unit to rotate accordingly, and therefore drive the twist vehicle to move forwardly. The twist vehicle further includes an anti-reverse system which includes at least two locking member provided to the pair of driving wheels respectively, and a pair of locking panels in which each locking panel has at least one biasing member for rotatably engaging with the locking member, so as to restrict the pair of driving wheels to be rotated in one direction only.
