Abstract: The teachings provided herein are generally directed to compact vehicle drive mechanisms that can be used in the design of a foldable, carry-on vehicle. The compact drive mechanisms presented herein, for example, have contributed to the advent of the compact, carry-on bicycles set-forth in the teachings which include drive-and-steering units and drive-and-chassis units.

Abstract: A method of using a folding vehicle having a chassis that functions as a protective, carry-on casing is provided. The vehicle has a chassis with a center member, a rotatably-lockable front strut, a rotatably-lockable rear strut, and two pivot points for converting the vehicle from an operational state to a collapsed state; and, a drive member with a crankshaft. The crankshaft and the rotatably-lockable front strut pivot share a central axis of rotation; and, the releasably-lockable front strut and the releasably-lockable rear strut are configured to fold into a complementary relationship in the interior of the channel in the collapsed state. The channel functions as a protective, carry-on case for the folding vehicle in the collapsed state.
