Designed and built in Perth, Australia, by road train driver turned stunt-jumper Ray Baumann, this car-crushing, two-wheeled behemoth is almost thirty feet (9 metres) long, ten feet (3 metres) high and weighs as much as a school bus.
Developed over three years, the 13.6 tonne Monster Motorbike is powered by a Detroit Diesel truck engine and six-speed Allison automatic and uses a two-speed Eaton differential from a road train to drive a massive chain on each side of the rear wheel.
The wheels and tyres themselves are from a Caterpillar 80 tonne front end loader and are almost 10 feet (3 metres) high and over 3 feet (1 meter) wide.

“We did stunt driving for quite a few years, broke a few records and broke my back a few times, so this is a way of taking a bit more care,” said Baumann.
