Abstract
An integral front fork and handlebar unit for attachment to the head tube of a bicycle includes a unitary member which is arranged into a handlebar portion for use in steering the bicycle, a front fork portion attaching to the front wheel of the bicycle and a connecting portion for joining together the handlebar portion and the front fork portion. The entire unit has a forward protruding wedge shape and is continuous in nature without any openings or voids with the exception of the front fork which splits into two front wheel support arms disposed on opposite sides of the front bicycle wheel. As part of the unitary and integral construction, a generally cylindrical post is provided on the center line of the unit and this post is received by the head tube of the bicycle in order to provide the rotational pivot for transferring steering forces from the handlebar portion to the front fork portion.
