As someone who has had plenty of bike pieces stolen over the years (including a carbon fiber fork just this weekend from my LOCKED garage) I like the idea of this bike. It is pretty sweet -- basically the entire frame is made from these short pieces that are connected through some type of ratchet mechanism within the frame itself. When you are riding the bike, the mechanism is in locked mode, and the frame is sturdy just like a metal frame. When you are ready to park it though, you just push a button and the ratchet mechanism unlocks, turning your bike into some kind of mutant gumby transport. You can then literally fold the entire thing around a pole as shown in the picture above and lock it to itself using a small, pocket sized u-lock.
I'm betting the gears only come fixed...
