They are the little and large of sport - while Bolt stands 1.95 metres, Biles measures just 1.45 metres - but they were both giants at the Rio Olympics and enjoyed an ecstatic welcome as they received their statuettes here, the birthplace of the first ever Laureus awards 17 years ago.
Bolt, who won this award in 2009, 2010 and 2013, walked away with the 'Oscar of Sports' for the fourth time, joining tennis legends Roger Federer and Serena Williams, and surfer Kelly Slater as four-time Laureus award winner.
"Thanks for the wonderful award. Laureus is one of the biggest awards for me. This is my 4th award and to be equalling it with someone like Roger Federer is great. I am in great company. It is special," he added.
Olympic gymnastics champion Biles notched up the 'Sportswoman of the Year' trophy, courtesy her brilliant show at the Rio Games, where she finished with four golds and a bronze.
