IN HIS life as a competitor Luke Madill has earned the sobriquet "Dr Smooth" for his style.
Now Madill is worthy of a new unofficial title.
He could be called a professor of BMX riding.
The unofficial Penrith prof has got all the qualifications for teaching: 11 times an Australian champion, an Olympian and an overseas racer.
"I've been teaching BMX riding at schools as part of the government's Get Active program," he said of the new career as an unofficial adjunct professor with a team of teachers.
"We go around the Hawkesbury and Campbelltown regions, have about 20 bikes provided and set up little dirt tracks."
Madill has another qualification for teaching keen kiddies.
He was once one himself.
He followed his brothers onto a bike at three and competed in his first national title at five.
The 33-year-old is back home at Cranebrook before returning overseas for competition in February.
"It's slowly gaining popularity and is getting a lot more respect," he said of BMX's exposure, and he's been in some media demand, scoring with a feature in Men's Health magazine.
"They [highlight] physicality, mental preparation, dietary needs," he said of the magazine's focus.
How long can he stay focused as an experienced competitor in what is seen as a young man's game?
"It's like football or other sports; as long as you're motivated."
But when it comes to competing in Europe he notes that "it's a big commitment and costs thousands".
Madill showed the extent of his own commitment when he built a replica track with the help of his sponsor Red Bull, after it was announced that BMX riding would be part of the Beijing Olympics.
The track is still there, Madill still trains on it and he also trains young riders there.
There's that old saying about once you've ridden a bike you never forget how, and it certainly has an application for Madill and the injuries he's suffered.
"I've had a broken back and broken wrists," he said; but of trepidation and confidence returning: "You get back on the bike and it's second nature."
