Today only, Apr 22, 2017, CitiBike has partnered with Mastercard to offer FREE CitiBike day passes to riders in celebration of Earth Day.

“Earth Day also marks the 2nd Annual Car Free NYC Day, where the NYC Department of Transportation will transform thirty blocks of Broadway into a bike and pedestrian paradise. The route will be filled with fitness classes, walking tours, dance performances, and of course, Citi Bikes!”
