A folding tricycle, maximizing the exercise effect by allowing a user to pedal the tricycle while standing up on the pedals, as well as being easy to move and carry by being folded to be of a small size, is disclosed. The folding tricycle has a running unit consisting of a main frame, two front wheels, and a rear wheel. The main frame consists of two frame parts with a first folding part jointing the two frame parts together, thus being foldable at the folding part. The two frame parts respectively have a front wheel shaft housing and a rear wheel support assembly. The tricycle also has a steering unit used for steering the rear wheel. The steering unit has a second folding part, thus being foldable at the second folding part. The tricycle also has a brake unit used for selectively braking the front wheels. In addition, the tricycle has a drive unit used for generating a rotating force and transmitting the rotating force to the front wheels through two front wheel shafts alternately acting as driving and driven shafts. The drive unit is designed to generate the rotating force from the pedals operated by a user standing up with both feet being placed on the two pedals. |
