## Abstract

A gyrocycle (10) comprising an elongated main body (12). A pair of front wings (14) extend from the main body (12). A pair of rear wings (16) extend from the main body (12). A front axle (18) extends transversely through the main body (12) and through the front wings (14). A rear axle (20) extends transversely through the main body (12) and through the rear wings (16). A pair of front wheels (22) are provided. Each front wheel (22) is mounted in a rotatable manner to one end of the front axle (18), so that the front wheels (22) can rest upon a flat horizontal surface (24). A pair of rear wheels (26) are also provided. Each rear wheels (20) is mounted in a rotatable manner to one end of the rear axle (20), so that the rear wheels (26) can rest upon the flat horizontal surface (24). A chair (28) is mounted onto the main body (12) adjacent the rear wings (16), so that a person (30) can sit in the chair (28). A facility (32) is built into the main body (12) for exercising, so that the person (30) sitting in the chair (28) can strengthen the triceps, biceps and abdominal muscles.
