Just like dating George Clooney means vacations on Lake Como, hooking up with Leonardo DiCaprio means bike rides (and lots of them). Leo was spotted out on a ride with his current girlfriend, German model Toni Garrn, who he's been vacationing with in Spain recently. The couple played a few rounds of tennis before biking back to their hotel in Mallorca today. We can't help but notice that Leo has a pretty obvious background of bike-riding with his babes — in addition to being great exercise and eco-friendly transportation, it seems to be one of the most common date ideas for the A-list actor. Here, a history:
