Arnold Schwarzenegger was spotted riding a bicycle in Melbourne without a helmet on Saturday, after being stopped by police for doing the same thing two years prior.

And just like his famous saying, 'I'll be back,' so too was the star's protective headgear on Sunday.

The 69-year-old was seen zooming around Melbourne wearing his helmet, and showcasing his muscly arms.

The film star and politician wore a grey CrossFit T-shirt with dark grey shorts.

The Terminator star looked relaxed as he pedaled around, wearing black and white Adidas sneakers.

In May 2015, he was stopped by police for not wearing a helmet while riding a bicycle around the streets of Melbourne.

In Melbourne, mandatory bicycle helmet laws have been in place since 1990, with police issuing fines or warnings to those who do not follow the rules.

On Friday, during a press conference, Arnold was gifted a helmet from a journalist.

Arnold is currently Down Under hosting multi-sports event The Arnold Classic.

'It's wonderful to be back in Australia,' he was heard saying to waiting media shortly after landing on Aussie shores.

On Friday, Arnold dodged a question about Donald Trump on The Project, after he and the American President had a feud.

'Do you think Trump will last the four years (of his presidency)?,' Arnold was asked.

In a surreal exchange, Arnold said: 'The Arnold Classic, we will be here for four years, much longer. I think for the next 400 years you will see Arnold Classic in Melbourne.'

Arnold is a prominent Republican who served two terms as the Governor of California from 2003 to 2010.

He stated last year that he would not vote for Trump in the presidential election.

The bitter fall-out between the two intensified when Arnold signed up as host of The Celebrity Apprentice, taking over from Trump.

In January, Trump claimed Arnold's tenure on the show was plagued by poor ratings, as he posted several tweets about the reality TV series.

The bad blood between the pair has continued, with Arnold announcing he was stepping down from Celebrity Apprentice this month after just one season.

He claimed the show has 'baggage', saying: 'With Trump being involved in the show people have a bad taste and don't want to participate as a spectator or as a sponsor or in any other way support the show.'

But the President hit back, saying that Arnold was instead fired from the show for 'pathetic ratings'.
