Robert Pattinson is a biking enthusiast.

Robert Pattinson is a hell on wheels in Australia. The “Twilight” star has apparently been busted by police for… of all things… riding without a helmet!

As it turns out, Rob rode right into a heated political debate. Adelaide’s bike helment law is under fire from cycling enthusiasts.

A group called Adelaide Cyclists is lobbying against the requirement.

Local radio station SAFM Adelaide set the Twittersphere afire when it Tweeted the news to the rest of the world.

“‏@SAFMAdelaide Twilight’s Robert Pattinson has been cautioned by SA Police for not wearing a helmet while riding a bike in #Adelaide,” it messaged.

Police were obviously making a statement; no one is immune from the bicycle helmet law. In fact, they reportedly responded after seeing photos of Rob riding his bike.

Group members estimate that police fine between 500 and 2000 bikers a year for riding without a helmet.

The South Australia police have published and eight-page booklet on bike rules of the road and it clearly states: “When riding, you must wear an approved bicycle helmet that is properly adjusted and securely fastened.”

Rob was spotted on a solitary bike ride in Adelaide right after he arrived there. He’s filming in Australia’s Flinders Ranges, the largest mountain range in South Australia.

He was wearing a pair of dark shorts, a white T-shirt, sneaks, hat and backpack, but alas, no helmet. He took in the sights in Adelaide. He wore his cap backwards and hid behind some dark shades.

Pattinson wasn’t fined or charged, although he could have been. Police reportedly just let him go with a warning.

Ok… so he’s no Lindsay Lohan. In her last run-in with police she crashed her $100,000 Porsche 911 sports car into the back of a slow-moving dump truck outside of Los Angeles. She was likely traveling in excess of 70 mph and heavily damaged the car.

To compound matters, she lied to police an claimed she wasn’t driving. But in Australia Rob has become a hot political football. Lindsay is just a hot mess.
