A modular scooter with suspension and collapsible components is provided. The modular scooter having a plurality of wheels attached to the underside of a large planar deck with a plurality of selectively, collapsible, telescoping handle bar posts configured for multiple riders thereon. The modular scooter also including a collapsible seat post and seat combination, allowing a passenger, such as child to sit during the ride. A wishbone, tilting suspension allowing a driver to lean into turns is also provided. The present invention also having the ability to be linked and interlocked remotely to other similar scooters or trailers and to be converted into other forms of three-wheeled transport such as, but not limited to a wagon, delivery scooter, and the like.

A bicycle is provided that can include front and rear wheels; a handle bar; and top, bottom, head, front seat, and rear seat tube members (each with a longitudinal axis) that form a frame that is suspended between the wheels. A distance between the head tube member and the front seat tube member can be 14 inches or less. The distance can also be one-half or less of the distance between the head tube member and the rear seat tube member. The longitudinal axis of the head tube member can intersect a longitudinal axis of the front seat tube member at 120 inches or less above a riding surface. The rotational planes of the front pedals of a front crankset can overlap a rotational plane of the front wheel. The handle bar rotates about a volume representative of an upper body of a front rider and/or cargo.

Various embodiments of side-by-side flexible adjacent vehicles, such as twin bikes, are disclosed including includes two vehicles joined together side-by-side by means of a plurality of interconnecting pivoted link bars. One or more driver riders may simultaneously or independently operate said side-by-side flexible adjacent vehicles. The side-by-side flexible twin bicycle may be configured employing different size bicycles, in-line multi-rider tandem bicycles, recumbent bicycles, mountain bicycles, and motorcycles of various types. These embodiments provide the vertical stability of a four-wheel vehicle while retaining the ability to lean into turns and ride over irregular surfaces affording for each of the riders the handling, ride and feel similar to that of a single conventional vehicles.

A clutch means includes an immobile tube (60) disposed between a top tube (2) and a head tube (6) of a bicycle frame, with a bearing portion (20) mounted to one of the facing end portions and axially supporting the end portions, whereby the top tube (2) and the immobile tube (60) are disposed so as to be capable of relative rotation. In the outer periphery of the bearing portion (20) and the immobile tube (60) axially supported therein, pin holes (22, 62) are respectively opened. The pin holes (22, 62) are bored at positions that are centrally aligned when a front fork (4) of the bicycle is are linearly positioned.
