A family of vehicles is presented which exploit dynamic controls to stabilize in-line two wheeled vehicles. The stabilization results in improved safety at high speeds and on uncooperative surfaces. Stabilization affords balance at zero speed without auxiliary support means. Transformational wheel base length affords high visibility at low speeds and low drag at high speeds. In wheel chair configurations transforming wheel base length allows navigation up and down stairs.

The invention provides a vehicle drivable in use by a person walking or running while seated comprising: a frame; a large diameter front wheel non-steerable with respect to the frame, a seat for supporting a user's weight while walking or running, the frame configured to carry the seat suspended on the front wheel, a small diameter, steerable rear wheel journalled to the frame at a steering pivot axis, the seat being rotatable forwardly with respect to the front wheel and comprising a seat base for supporting a user and further comprising a backrest for engaging the user's back in use. The large front wheel may be of approximate diameter of a user's leg (typically an adult human), thus the large front wheel may be of similar size to a bicycle wheel for the user.

Various embodiments for an apparatus and method for use of a footrest device with a stationary bicycle are provided. A footrest device includes a forward foundation, a rear foundation, one or more posts that extends in a horizontal direction, wherein at least one end of the one or more posts is coupled to either the forward foundation or the rear foundation. The footrest device includes a platform configured to function as a footrest, and one or more support shafts that extend in a vertical direction upwardly from the one or more posts. A method for using the footrest device includes placing one foot on a platform of the footrest device, placing a second foot on a pedal on the opposite side of the stationary bicycle, and pedaling the pedal of the stationary bicycle with the second foot while the first foot is located on the platform of the footrest device.

The invention relates to an auxiliary mobility system for a wheelchair, comprising a frame, at least one wheel-bearing part and at least one steering element or handlebar, said bearing part being connected to the frame such that it can rotate concentrically about its axial axis under the action of the steering element. The system also comprises means for rotating the bearing part concentrically in relation to an axis substantially parallel to the rotation axis of the wheel.

The system of the preferred embodiments includes at least two wheels, where the wheels are mounted on axles, where the axles are attached to a frame, where a seat is attached to the frame, where the seat is designed to allow a user to slide along the seat and off of at least one end of the seat. The mobility scooter of the preferred embodiments is designed to allow a user to slide from the seat of the scooter directly onto other types of seats, and then slide back onto the scooter, allowing the user to get around much more easily and with far less strength that they would have to with any other type of scooter or wheelchair.
