Zayn Malik rides tiny green quad bike while sporting a rock band vest during some downtime in Sydney

You would think Zayn Malik would be able to get his hands on a much more size appropriate bike compared to the tiny one he was spotted driving on Wednesday.

The One Direction star revved up a bright green quad bike during some time off in Sydney, where the band are currently touring.

The 20-year-old looked far too big for the four-wheeled machine as he drove around backstage sporting a very casual outfit.

The singer, who is engaged to Little Mix singer Perrie Edwards, wore a fun green and purple baseball cap with the words The Joker emblazoned across the front.

His numerous tattoos were clearly visible in his black Gun N Roses vest and matching skinny jeans.

Zayn clearly enjoys jumping behind the wheel as he was pictured driving a much sportier looking go-kart on Sunday.

Wearing a red T-shirt and blue jeans, the singer was seen completing a few laps backstage in Brisbane while fans screamed and cheered him on.

Bandmate Harry Styles was also seen enjoying some time off on Tuesday when he indulged in a round of golf alongside Australian tennis player Pat Rafter.

Clearly a fan of the sport, Harry looked deep in concentration as he took aim on the picturesque golf course.

Harry's was pictured enjoying his new hobbie after he and bandmate Liam Payne, 19, were seen embracing each other on stage as they performed for fans the night before.

One Direction are wrapping up the Australian part of their Take Me Home tour this month after performing a whopping 131-dates across the globe.
