DB Rad+ and Call a Bike Scavenger Hunt in Cologne
Cycle through the city and secure great vouchers worth between €2 and €10 each.
Hop on your bike, grab your phone, and off you go!
It’s that simple
We’re turning Cologne into a treasure map—and you’ll pedal your way to the prizes. From March 9 to 30, 2026, Cologne transforms into your very own scavenger hunt arena: Each week, discover 20 new spots around the city and collect attractive vouchers as you cycle by. The app lets you know instantly if you’ve won.
What you need: a bike of your choice, your smartphone, and the DB Rad+ app—then you’re good to go!
What you can win
During the scavenger hunt, you can win vouchers from the DB on-board bistro, REWE, Rossmann, Amazon, Call a Bike and Flinkster. The vouchers have a value between €2 and €10 each.
You can win a maximum of one voucher per point and week. There are vouchers available while supplies last. So it pays to be quick!
Conditions of the campaign
No registration with DB Rad+ necessary: Download the DB Rad+ app and enable geolocation notifications in the app's privacy settings. This way, your kilometers will be counted, and we can display your vouchers.
Any bike: You can ride any bike to take part in the campaign. Take your own or rent a Call a Bike.
Start: Press the start button in the DB Rad+ app and begin your tour.
Redeem vouchers: When you reach one of the scavenger hunt points, you will receive a push notification. If you win and like what you see, please accept the voucher immediately. At the next point, the notification will replace the previous prize, and you cannot retrieve it. To redeem the voucher, you need at least 1 km in your kilometer account.
Have you won? Congratulations! Confirm the voucher immediately in the app. It will be added to your DB Rad+ Wallet and you can use it on your next purchase.
Free of charge: Using the DB Rad+ app is free of charge. It is not possible to pay out, refund or exchange the vouchers.
