The Chicago Offline Bike Map allows you to reference a map of Chicago streets and bikeways without a data connection. The entire map is stored on your iOS device. The map is designed to look much like the City of Chicago’s official printed and online bike map.
Download Chicago Offline Bike Map in the iTunes Store.
The app shows the locations of bike lanes, shared lanes (where there are “sharrows” on the pavement), cycle tracks (also known as protected bike lanes), and off-street trails (like the Lakefront Trail and Major Taylor Trail).
Updates will be made monthly in order to ensure the app has the latest bikeway and OpenStreetMap data. The second version, a free update, will include a “locate me” function, train stations, and other interactive features. And all of those are possible without a data connection.
The app is quite large (over 100 MB) because all of the map data is downloaded and stored to your phone. This is ideal for people without data connections, or without active wifi, or those who have low data limits.
