Even if you don't pedal to work during this week devoted to carless transportation, you'll still find plenty to do. Highlights of this year's programming include a bike-in screening of Rushmore in Millennium Park (June 16), a free two-hour bike tour (June 18), a free spin class at the Bean (June 19) and a celebratory Bike Rally on Daley Plaza (June 20, 7am-9pm).
