It's all about bikes today on Worldview. On today's show:

• We talk with journalist Nick Mead, who has spent the last two years reporting on what cities are doing to increase the number of bikes on the roadways.
• We link up with Working Bikes, an organization that “rescues discarded bikes and gives them new life as tools of empowerment” to talk about their recent projects abroad and their upcoming bike giveaway in Lawndale later this month.
• Chicago's “Bike Commuter Challenge” begins on Friday, June 10th. Are you ready?
