Former tennis pro Boris Becker rides around on one of London’s Barclays Cycle Hires, also known as Boris Bikes, during the ATP World Tour Finals at O2 Arena on November 23, 2010 in London, England.

This one-time top ranked tennis player from Germany is a six-time Grand Slam singles champion, an Olympic gold medalist, and the youngest-ever winner of the men’s singles title at Wimbledon at the age of 17. Boris also won four year end championships titles including three ATP Masters World Tour Finals and one WCT Finals. These days, Boris sometimes provides color commentary at tennis matches for BBC.
