Get on your bike in summer and even get rewarded? The new campaign from DB Rad+ and Call a Bike makes exactly that possible - with a bicycle scavenger hunt through Berlin and Hamburg. Those who take part can rediscover the city and collect vouchers - easily via app and on two wheels.
With Call a Bike, taking part in the bike scavenger hunt is easy and flexible.
From June 23 to July 20, 2025, bicycle enthusiasts in Berlin and Hamburg have the opportunity to take part in an interactive scavenger hunt. Every week, 20 new geopoints are waiting to be discovered by bike - and there is something to be won: Vouchers worth 5 euros.
Taking part is easy
Users can select their respective campaign area - Berlin or Hamburg - via the Rad+ app and start cycling straight away. Registration is not required. The prerequisite is that at least 1 km has been collected on the kilometer account.
The geopoints change weekly, which provides an additional spirit of discovery. Attractive vouchers from partners such as Budni, Rewe, Amazon, Rossmann, DB travel vouchers, Call a Bike and StadtRAD Hamburg await you along the way. These are stored directly in the Rad+ Wallet and can be redeemed there.
The aim of the campaign is to promote cycling in the summer in a fun way - and at the same time to encourage people to use Call a Bike, StadtRAD Hamburg and the Rad+ app.
