Foldable bikes have been around for some time, but Sada Bycicle pushes the limits of space-saving design by folding to the size of an umbrella. This hubless bike features a frame that folds away for maximum portability – it can even be packed in a regular-sized backpack!
The Sada Bike has a standard bicycle dimension with 26-inch wheels that are attached to the frame using an anchoring system. The entire structure can be folded with a single movement and packed in a container that can also be used as a backpack.
The design focuses on the bike’s space-saving advantages. Unlike most bikes, which usually get their strength from the tension in the spokes, the strength of the Sada Bicycle is put into the rim. This adds weight to the outside wheel, which can become a performance issue. However, the prototype is currently designed as a model for the city. The designer is seeking funding in order to further develop the design, which could allow him to tackle the weight issue and manufacture a model that combines light-weight bicycle design with high performance.
