A two-wheeled, variable configuration bicycle having a frame, a handlebar, a saddle, pedals with pedal cranks and a drive gear rotatably mounted on the frame, a front wheel mounted on the front fork, a rear wheel with a sprocket mounted on a rear fork. The bicycle includes the upright configuration and the recumbent configuration, and in recumbent configuration, the bicycle provides support for the back of the cyclist. The frame (2, 2) are provided two front mounting locations for attaching the front fork (14), wherein the first front mounting location is provided for attaching the front fork (14) in the upright configuration, and the second front mounting location is provided for attaching the front fork (14) in the recumbent configuration. The frame (2, 2) are provided two rear mounting locations for attaching the rear fork (17).

A means of providing motorized locomotion to a mobility device such as a wheelchair utilizing a first portion of the present invention configured to attach immovably but releasably to an array of mobility devices and configured to interlock with the second portion of the present invention, which is configured to attach immovably but releasably to an array of electric scooters. A movable feature permits the first portion and second portion of the present invention to be interlocked while keeping all wheels of the mobility device and the scooter in contact with the supporting surface. A stand for the electric scooter lowers when the two units are separated and lifts when they are engaged, to hold the electric scooter in an approximately vertical position when not engaged and to provide freedom of movement when engaged.

A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

A motorcycle conversion kit for a three wheeled motorcycle wherein the conversion kit of the present invention is operable to transition the motorcycle so as to traverse across a snowy terrain. The conversion kit of the present invention includes a pair of ski assemblies that are operably secured to the front rotor assembly of the motorcycle. The ski assemblies include rotor movement inhibitors. A swing arm assembly is operably coupled to the frame and includes a front portion and a rear portion. The rear portion has rotatably mounted thereto a snow belt drive wheel. The show belt drive wheel is superposed a snow belt of a snow belt assembly wherein the snow belt assembly is secured to the frame of the motorcycle. The kit further includes a fuel cell bracket assembly having support members mounted on opposing sides of the frame and having a compartment rearward of the motorcycle.
