Abstract: Improved components are provided for a bicycle which is powered by pedals, motor, or engine. Such bicycle can be folding or non-folding, The two components are 1) lever-locked handlebars mounted upon a sturdy steering column and 2) a sturdy offset seat column which can be height-adjustable. Included is a handle bar assembly having a pair of foldable handle bars mounted to a center section, which is mounted in turn on a steering column. Each of the handle bars has a cam mounted thereto with a lever attached to the cam, so that when each handle bar is pivoted up to its extended operating position, a lever and cam are pivoted so that the cam overlaps the center section in close proximity, holding each handle bar in such extended position. Pulling the levers out of their respective pockets and pivoting them and their cams in the reverse directions, releases the respective handlebars so that they can fold downwardly toward the steering column in a compact manner.

Abstract: The folding bicycle which includes front and rear wheels and a sprocket and pedal assembly mounted to a frame and a steering column and a seat column mounted to such frame, is provided wherein the seat column and the steering column fold into proximity with the frame and substantially in the plane of the frame, while the rear wheel and sprocket assembly pivot around the sprocket axis into proximity with the frame and the front wheel, also in the plane of such frame.The seat column has a bend or goose neck below the seat thereof to permit the seat column when folded toward the steering column, to curve around the base portion of the steering column and permit the steering column to fold thereover in planar proximity.Other features of the planar folding bicycle include foldable handle bars and foldable pedals and a sprocket belt drive which is positioned against the drive gear of the rear wheel by an adjustable nip guide roll.
