DB Rad is a free Android app developed by Scholz Volkmer GmbH that encourages people to use bicycles as a means of transportation. The app allows users to track their cycling activity and earn rewards for every kilometer ridden.

To get started, users simply need to download the app and activate it when they are cycling in participating cities. The app records the kilometers traveled, whether on a personal bike or a shared one, and converts them into rewards that can be redeemed at local partners such as cafes, museums, and farm shops.

One of the most significant aspects of DB Rad is the community aspect. As kilometers are accumulated, the whole community benefits from bike-friendly infrastructure and events initiated by the local government or Deutsche Bahn.

DB Rad is a pilot project developed as part of the "Initiative Zukunftsbahnhöfe" of Deutsche Bahn, and it is gradually being offered and improved in more locations.

Overall, DB Rad is an innovative way to promote sustainable mobility and a great initiative to reduce carbon emissions.
