NextBike are one of the leading bike sharing schemes in Europe. When people rent a bike they are supposed to return the bike to an official bike station, however frequently this does not happen and the bike is left somewhere.

We created an app that turned the process of finding these stray bikes into a game and reward you when you then return the bike to an official station.

Starting the app our systems look for a stray bike within 1.5 miles of you. Once a random stray bike has been chosen you then track that bike by playing the hotter or colder game. The closer you walk to the bike the hotter you get. When you find the bike you can then choose to ride the bike back to an official station. Doing so will gain you a reward ranging from a 2 hour free voucher code, to a 6 month subscription. Get finding those bikes...
