From Italian designer Gianluca Sada comes The Sada Bike, a bicycle that can fold to the size of an umbrella. The wheels have a hubless design with no spokes, which allows for the deconstructed bike to be more compact than prior folding models of like size. Once completely folded, it is carried in a backpack as seen in the video, and the designer states that it can be carried on during air travel. Though commenters on the YouTube link mention the Lifetime Movie Channel-esque music on the video as well as the folding process not being shown, all seemed interested in the concept of this easily portable bike.
