A quad bike that doesn’t roll is one of the finalists for the James Dyson Award.
Tahr Quad was designed by Nick Marks.
Four wheel quad bikes popular for farming can roll over in difficult terrain causing 850 injuries in New Zealand every year. Tahr Quad is a bike designed specifically for farming. It uses a completely different suspension and chassis system in combination with intelligent computer technology to prevent four wheel vehicles from rolling.
Nick Marks, a 24 year old designer from Torbay, Auckland designed an automatic balancing system, which borrows its principle from two-wheel bikes which lean into corners. Internally it gyrates and shifts the bike’s mass and lowers its centre of gravity, stabilising the vehicle and rider. All four wheels are designed to maintain contact with the terrain. . .

This sounds like a very good invention which would be much safer than conventional quad bikes.
Other finalists for the award are: Cortex, a lightweight and breathable cast for fractured bones designed by Jake Evill, and Fabseat, a desk chair that people can create for themselves by using materials that have been cut to their individual body measurements and cushioning preferences, designed by Evan Thomas.
