Chicago Uber users will see a “Bike” option on their drop-down menu, appearing just above the “Payment” tab. Once they select the bike option, users inside the designated zone will see available Jump bikes nearby and can select one to reserve. The app will give a numeric code to unlock the bike. The bikes also can be accessed via Jump’s app. Riders can use the map in the app to find and reserve bikes, or just walk up to a bike, enter their account number and the numeric code and ride.
