This dramatic looking mode of transportation is said to be the modern day replacement for the skateboard.
Using a single large bicycle (or I guess that would be unicycle) wheel in front and a smaller caster in the rear for steering, it lets you achieve speeds up to 20 miles per hour, simply using your own leg strength to kick off.http://www.youtube.com/watch?v=M1OGHuGSPAw
According to the inventor of the wheel (I always wanted to say that,) its designed as an alternative to skateboards, scooters and roller blades, and is a great way to get around quickly. While it takes a bit of getting used to balancing on the wheel, it’s supposed to take just a couple of hours to get the hang of it.
Magic Wheel is accepting pre-orders now for £119 (appx. $245 USD plus shipping.) They expect to start shipping a fresh batch of them this August.
