Sobi is short for Social Biking. The bicycle fleet has been implanted with GPS that ensures good tracking and prevention of thefts. The Sobi server keeps all the data, information and records about which bike has been rented out by whom. The GPS has been placed in a box that doubles as a carriage with LED lights. Dedicated kiosks along the way help the users to register and log in to the system. Thus, one can ride around in the greenest manner possible.
