Folding bikes are a great solution for city dwellers, because when you're done with your ride, you can simply carry the bike into your office or apartment. This concept bike called the Union takes the folding idea to new extremes, breaking down into a package that's just eight inches across.
Created by designers Weiche Wu & Minhan Lin, the Union is easy to carry on public transportation, and can be unfolded in five simple steps. It looks like a neat package, but I'm a bit concerned about those tiny wheels. They might be fine if your town has streets as smooth as a pool table, but here in New York we have potholes as big as the whole bike.
Currently the Union is only a concept.
