Creative bicycles, long a favorite subject of student industrial design contests, are busting out of art college and onto the streets. This year, there's been an explosion of creative frame designs across the cycling spectrum — road, mountain, electric, commuter — that are nothing short of sculpture on wheels. And unlike a lot of artsy inventions that are good only for mounting on a wall, these two-wheeled wonders not only work but also offer some innovative functional capabilities not seen on bikes with the century-old diamond-shaped frame.
