You're green. You like things that are different, not just for the difference, but because they work. Take the bicycle. We're all pretty familiar with the basic shape of the bicycle, which hasn't changed much since somebody decided that being perched astride one ginormous wheel was sort of dangerous and hard to ride and would be mocked in later years. So the basic bike shape has remained about the same, until now. Why not make it a triangle, which is then foldable and totally portable?

Thus the Strida. It weighs just 22 pounds, holds riders up to 6'4" and 220 pounds (there's also a Tall version and a Mini version for a more custom fit), and did we mention the folding part? It folds into a compact elongated shape 45" x 20" x 9", which is a lot easier to take along on the bus/train/elevator and to park later at the office than a standard bike. Plus? A greaseless belt drive instead of a standard chain (if you've ever caught your pant leg in a black-greased bike chain, you'll know why this is important).

Like it? So did we when we saw—and coveted—one at this year's Consumer Electronics Show. It retails for $800 (though you can find it for less if you shop around a bit), and available accessories include saddlebags and an iPod backpack. Of course. And the bike looks about as travel-friendly as a stroller; we're betting you could check it on your next flight and have a bike to ride at your destination. Green(er) travel!

Watch how the Strida's inventor, Mark Sanders, came up with its design. Ingenious!
