Why bother with two wheels when you can ride inside of one. The Wheelsurf is an extreme vehicle that will rocket you from 0-40km'h in 8.2 seconds. The price is $4,600, but can you really put a price on something like the WheelSurf?
The company's website describes, "The Wheelsurf is pure adrenaline. It is one of the most distinctive vehicles on the planet -- a single-wheeled , ride-inside conveyance that's sure to get you noticed. Riding the Wheelsurf is not for those seeking transport alone."
