What's faster across the city of Chicago, a top bike messenger or a taxi? In this video, we find out.

Nico Deportago-Cabrera is one of the world's fastest bike messengers, according to Red Bull, who made this clip. Does he know the streets of Chicago better than a cabbie? And if he does can he get from downtown to the northern centre faster?

They set out at the Willis Tower, formerly known as the Sears Tower and the tallest building in the world from its completion in 1973 until the Petronas Twin Towers in Kuala Lumpur, Malaysia claimed the title in 1998.

Their destination is Wrigleyville, location of the Chicago Cubs ground at Wrigley Field, which you may remember from the movie The Blues Brothers.

It's 5.6 miles by bike, 7.2 miles by car, but the cab can take the fast freeways while Nico has to battle surface streets with their traffic, lights and slow-moving buses.

Who's fastest? Whose machine reigns supreme? Watch and find out.
