The world’s most popular cycling bike has its roots in a little-known Australian sport, and it’s still getting its legs under it.

The Dirt Bike is Australia’s fastest and most popular recreational bicycle, with the sport growing rapidly and now attracting riders from around the world.

It’s a sport in which the riders don’t care about their appearance, but rather their ability to push themselves to the limit.

Dirt bikes are not new.

The sport began with an original British bicycle designed in the late 1800s, called the “Door-Door”, and was popularised in Australia in the 1950s.

Since then, dirt bikes have gained popularity in the US, France, the Netherlands, Germany, and more.

Australia’s Dirt Bike Association says there are currently more than 100,000 dirt bikes in use in the country, with more than 1,000 registered riders.

Riders don’t necessarily follow a strict diet, however.

“We don’t drink or smoke.

It’s a fun way to travel,” says Mark Bowers, the Dirt Bike Club’s national chief executive.

Bowers says that when he first started riding in Australia, he’d only ever ridden dirt bikes once or twice a year.

He’d also only ever rode dirt bikes on roads with a straight track, where riders had to avoid cars and other cars and cyclists.

With the advent of roads and pavements in Australia and the internet, Bowers says there has been a huge jump in riders, from just a few riders to dozens.

In the past couple of years, the sport has been embraced by the broader community, and is becoming increasingly popular with people from across the world, from New Zealanders to Germans.

More than 10 million Australians have been dirt bike riders, and the number is growing.

Australian dirt bike clubs have a presence across the country.

A recent ride by Australian dirt bike club members from New York, New Zealand, the UK, the US and the Netherlands went on to win a $50,000 prize at the 2018 American Dirt Bike Championships.

At the end of the day, the dirt bike is a great way to get away, and enjoy the outdoors, says Bowers.
