Abstract
A tricycle features a hollow main frame member to which a pair of rear wheels and a seat are mounted. A head tube is attached to the main frame member and a post is pivotally positioned therein. The tricycle front wheel is connected to the lower end of the post while handlebars are connected to the upper end of the post. A steering miter gear is also attached to the post within the head tube. A steering shaft is rotatably positioned with the hollow main frame member and features miter gears on its leading and trailing ends. The miter gear on the leading end engages the steering miter gear while the miter gear on the trailing end engages a miter gear that is removably engaged by a pushing and steering handle. The tricycle thus may be pushed and steered by the handle.
