A foldable bicycle is provided. One feature of the foldable bicycle is that the central portion of the frame that defines the bicycle's geometry is substantially rigid. That is, the down tube, seat tube, top tube and bearing tube are substantially fixed relative to each other. Another feature of the foldable bicycle is that the front wheel can be folded into a position between the down tube, which is comprised of two tubes. Yet another feature is a tandem bicycle configuration that does not extend the length of the frame or the wheelbase. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
