Stunt cyclist takes on San Francisco

An amazing video of a Scottish stunt cyclist taking his skills to the streets of San Francisco is going viral online.

The clip of Danny MacAskill performing his daredevil stunts in the iconic Californian city has notched up 200,000 views on YouTube.

Mr MacAskill, 26, rode down the city's famous hilly streets and its historic neighbourhoods in search of a new set of tricks to perform.

He climbs walls, sculptures and even trees with his custom-built Inspired bicycle in the video, sponsored by razor maker Remington.

"I always feel like I've had a different way to view a city. When I'm looking around the streets, you can visualise how you'd ride different features," he said.

"It's just kind of a natural thing you'd have in your head. You're kind of looking around seeing how you can jump on that rail and then maybe jump to this wall."

At one point in the four-and-a-half-minute video, he rides along a narrow metal railing overlooking a cliff and a highway far below.

"When you're riding along the top of a spiky fence or along a railing, you really have to focus 100% and really put everything into it," he said.

"You think you're gonna come off at any second, but somehow you manage to piece it all together and make it to the end."
