A tricycle includes a frame mounting a single large diameter rear wheel and a pair of small diameter front wheels. A pedal crank mechanism is connected through a chain and sprocket to drive the single rear wheel. The front wheels are mounted on front fork members disposed at opposite ends of a transverse steering bar. A perpendicular attached steering rod extends through a head tube on the tricycle frame and connects with a handle bar having an elongated central portion extending parallel with the transverse steering bar. A rectangular basket is disposed forwardly of the steering rod and includes a pair of spaced parallel vertically extending corner frame members secured between the central handle bar portion and the transverse steering bar. The tricycle provides a stable and efficient vehicle which may be utilized by individuals for shopping and exercise purposes.
