The Monster Motorbike that can crush its way through the rush hour

Here is one motorcycle that no-one on the road is going to mess with - this bike can crush cars.

The Monster Motorbike is three metres high, nine metres long and at 14 tonnes, it weighs more than a double decker bus.

Ray Baumann took three years to build this beast of a machine that can simply roll over most other vehicles.

Its two giant wheels and tyres are taken from an 80-tonne Caterpillar digger and are driven by two huge chains powered by a six-speed diesel lorry engine.

At ten times the weight of a family car, it is the world's biggest motorcycle and is more than a match for any road hog.

Retired stuntman Mr Baumann takes the Monster Motorbike to shows and demonstrates its astonishing power by crushing cars and caravans.

The former lorry driver, whose stunt career involved jumping cars, said: "I 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.

"Now I crush things, which is definitely less risky than jumping them."

It was designed and built in Perth, Australia, and uses a Detroit Diesel engine and six-speed Allison automatic gearbox from a lorry.

It also has a two-speed Eaton differential from an articulated lorry to drive a massive chain on each side of the rear wheel.

Mr Baumann said he and his team are looking forward to taking to the road with the giant bike.

He said: "This is just its first season out after spending three years working on it.

"We are getting it running right and then we will take it on the road.

"When we designed it, we kept the weight down low, so it isn't easy to roll over.

"However, it could roll if we ran over a car the wrong way, so we still have to be very careful.

"It's well and truly dangerous, just not as dangerous as the car jumps."

The bike is to go on show at the Australian Motor Show in Melbourne later this month.
