A bicycle or other two wheel vehicle includes a frame (12) formed as a continuously curving arc. A front fork (20) is pivotably attached adjacent to a front end of the frame, and may have a curvature matching the curvature of the frame. The frame may be formed from a hollow thin wall tube bent into an arc. The frame typically has a round, oval or elliptical cross section, and may subsume an arc of 120-180 degrees. Drive line components, such as batteries (40), motors (44, 46), etc. may be installed within the frame (12).
