摘要
A bicycle frame includes a top tube, a head tube rotatably coupled to a forward portion of the top tube about a first pivot, a seat tube having an upper portion rotatably coupled to a rear portion of the top tube about a second pivot, and a chain stay rotatably coupled to a lower portion of the seat tube about a third pivot. The head tube and the seat tube each pivot between operating positions away from the top tube and storage positions substantially along the top tube, and the chain stay pivots between an operating position away from the seat tube and a storage position along the seat tube.
