This is how it works
You can rent a Donkey Republic bike by downloading the app, finding the nearest available bike and unlocking it electronically. You can keep the bike for as long as you want, lock and unlock it as needed and when you are done with the bike just put it in a publicly accessible place, lock it and end your rental period in the app.
