Cool. Looks fun, although a bit awkward. Looks really difficult mechanically, though - a motorbike arrangement gives you a lot more space to play with, and the chassis is much simpler.
The speed record on one of those is nearly 100 km/h, although balance is complicated by the enormous set of balls you require to attempt it.
