The people at Sinclair Research have been hard at work at developing a compact transportation device, and it has all culminated to this point: the launch of the “A-Bike”, the world’s lightest folding bicycle.

This is a great invention for people who are tight on space, hateful of the rising gas prices, and want to get a touch of exercise while they’re at it. It takes only 10 seconds to fold up the A-Bike, and the same amount of time to unfold it before you can hit the streets. Best of all, this offering from Sinclair is a mere 12 pounds!

Interestingly, although it has some rather tiny wheels, the pedal power required isn’t all that much different from a regular bike, and because the chain system is fully enclosed, you won’t have to worry about getting your pant legs pulled in and torn.

Here’s a video of the A-Bike in action:
