Miami Heat stars Lebron James, Dwyane Wade and Mario Chalmers biked through Miami for Miami Critical Mass. It’s about a 12-18 mile event held on the last friday of every month where bicyclists and, less frequently, skateboarders, inline skaters, roller skaters and other self-propelled commuters take to the streets en masse. It encourages cycling and reminds drivers that they must share the road. Looks like a really fun event, check the pics after the jump. Shay Marie
