Streetcars go where people want to be. They make the best street in the neighborhood a safe place to bike no matter how old you are.
Some of the pictures here show people biking in streetcar lanes, which can be dangerous if you're not careful because your wheel can get caught in the tracks.
The Chicago Streetcar Renaissance plan does not mix bikeways and streetcar tracks. We're pushing for wide, separated bikeways between the tracks and the sidewalk.
