On court, Canadian tennis player Milos Raonic is all about the art of winning.

Off court, he is all about the art, or, to be specific, the art of Andy Warhol and Ai Weiwei .

The 25-year-old and his girlfriend, model Danielle Knudson, visited the blockbuster exhibition at the National Gallery of Victoria in Melbourne yesterday, as part of a promotional event for the Australian Open tennis tournament.

One of the installations that caught their eye was Ai's Forever Bicycles series, composed from more than 1,500 bicycles.

When the Chinese artist, now 58, was growing up, a Forever Bicycle was a luxury, reported The Sydney Morning Herald.

If one bike symbolises the freedom to move, then imagine more than 1,500 of them piled 9m high, in a dizzying structure that one can walk around and peer through.

The frames and wheels hang static in the air in a tunnel of steel, representing endless possibilities and future pathways for the young artist in Beijing.

And, perhaps, for the young tennis player yesterday too.
