Hubless folding bike


The Sada bike can be folded in a single movement.

With 26-inch wheels which are attached to the frame using an anchoring system, the entire bike folds down to the size of an umbrella which fits into a container.

Designed for city use, the prototype bike's performance is compromised by the fact that the strength is in the rim, making the outside wheel heavier. The designer is looking for funding to improve the prototype by reducing the weight without compromising performance.
