Folding bikes are nothing new. The thing about them is that they require you to perform mechanical origami each time you want to change states. That sucks.
So now, Xootr is releasing the Swift, which has the notorious distinction of not taking much more than three seconds to go from fully functional to fully folded. The way you do it is brilliant. Simply pull the seat up, and the entire frame collapses forward, becoming instantly portable. At all of 22lbs, you can take it on the bus, under the desk at the office, etc.
