It started out a few years ago as an offbeat honours project at the University of Adelaide, Australia, and has since evolved into something rather special (that is, in the arcane field of human-operated diwheels). Not surprisingly, we love it.
In essence, it’s an electric-powered diwheel with quite a bit of functionality absent in similar machines, such as built-in dynamic lateral stability and slosh control to prevent “gerbilling” or tumbling during aggressive braking or acceleration manoeuvres. Keeping the vehicle in its unstable state is achieved using a combined swing-up and inversion controller. It also incorporates a unique feature that allows the rider to drive upside down. Top speed is around 40 km/h, and the diwheel is said to climb a maximum incline of 12 degrees. The sealed lead-acid batteries provide an operating time of about 1 hour.
What’s it for? That’s a ridiculous question. You should be ashamed.
