Here's something that'll make you think twice before your next bike purchase -- the geniuses (genii?) at Yale University have built a pretty rad spokeless bicycle, which was somehow inspired by the lack of "pictures of a real spokeless bicycle online." Sure, strictly speaking it's just a half-done product due to time (one semester) and budget restraints, but that rear wheel -- driven by the pedals on its geared inner rim -- alone should be enough to make you gasp. Practical hipsters might even be able to fit an electric motor or some sort of container inside the wheel, although we're pretty content with the futuristic hollowness. Either way, the Yale grad who posted these photos is now available for hire, so pay him well and you can have it your way.
