Most urban style folding bikes give up sleek styling for practicality and compactness, but not this concept model from German bike manufacturer Cube. Looking a bit like a sleeker version of the Cannondale On, the USC was designed by Coburg University of Applied Sciences student Gregor Dauth, who says it folds to a size small enough to fit into the tiny Smart car. Far from being a bare bones unworkable concept, the USC includes such practical features as a built in generator hub for the integrated LED lighting that switches on automatically when it gets dark.

No word about potential availability, but a bike this cool might even get me to follow my Doctor's advice and get some exercise.
