YAAAAAH!! Totally Awesome. I'd love to test that thing out and stress it.

As someone else commented, where's the drivetrain? Are the pedals actually connected to anything? Interesting that the bike is never shown actually being pedaled!

So true.. the devil is in the details, yet I'm still curious as to the design potential. Someone mentioned a drive shaft. There seem to be existing designs out there for that, but I don't know if they've been proven.

It's an interesting concept but I find the lack of a drivetrain to be a huge issue; I can't see a way to easily get around that although they may have a solution they are not showing until the bike is released or a patent is complete.

The one other thing I noticed is that if you look closely the seemingly smooth transition to the folded package seems to require a lot of precise movement and control; it all looks VERY practiced. I have to wonder how well it folds up for a first timer with little to know mechanical aptitude.

While cool in how small it gets, the fact that they haven't been able to put a functional drivetrain or brakes (look closely, no pads on the rotors) kind of hints to me this won't be on the market anytime soon. Wish I didn't have to be skeptical though.

Here's a quote: "The prototype pictured right uses hydraulics instead of the traditional chain; oil pumped inside tubes through the frame of the bike powers the back wheel, doing away with the oil and grease that comes with chains."
