A tricycle having two front steering wheels and a rear drive wheel has a frame for accommodating the rear wheel and a mount pivotally connected to the front of the frame carrying a pair of front steering wheels. Handle bars are connected with a tie-rod assembly to the supporting forks for the front steering wheels. The mount has a parallel linkage which allows the frame and the front wheels to bank to facilitate the turning of the tricycle. A basket is suspended below the mount between the front wheels. A lock connected to the beams holds the beams in fixed relation relative to each other. The lock can be released to limit the angle of the bank of the tricycle.
