Your average electric bicycle has a basket on the front and a lot of shame in the rear. Not the Grace One. When we first saw it almost two years ago, in the fall of 2009, it looked… well it looked like a pretty kickass bike. Since then the design has been thoroughly refined, the frame redesigned, but still the stacked projector headlamps remain in their aluminum housing in front of the bars. They're a hint at the high-tech nature of this bike, which features integrated Li-ion batteries that charge in about an hour and spin a hub-mounted motor in the rear wheel, giving you a top speed of 30MPH and a range of up to 31 miles — all for a mere €4,199 ($6,000).

All that’s need is to soak the tent and wait. It takes about 24 hours for the tent to harden, transforming into a permanent structure that can be sterilized and wired for electricity.

The BCC just posted a video interview with the founders who explain how the material came to be and the company’s plans, but if nothing else, click through just to see this stuff in action. I want one for my backyard shed. Put together a standard Home Depot barn is for jerks.
