Cycling and getting rewarded for it—too good to be true? Then Radbonus is perfect for you! With Radbonus, you can track your cycled kilometers and cycling days, earning attractive bonuses to motivate you to ride more. In cooperation with our partners, we challenge you to participate in challenges, battles, and missions. The rewards vary and include fixed prizes (everyone who completes the challenge gets the prize), raffles (everyone who completes the challenge is entered into the draw), and discounts. Challenges Challenges give you the opportunity to earn rewards by reaching a specified kilometer goal. Want to pursue your own goals? You can now do so with the new Radbonus feature. Create a custom goal, whether it's a certain number of cycled kilometers, CO2 savings, calories, or saving money for a financial goal (e.g., a new rain jacket for €70). Do you love measuring your performance against others? Then individual and team battles are just for you. Besides the existing battles, you now have the option to invite up to 10 friends to a private battle, where you compete on a leaderboard. You can set a fixed time frame or a kilometer goal. With a prize for the winner, the motivation to pedal hard is even higher! Is community important to you? Then you can collect kilometers together in missions. Tracking kilometers Tracking your kilometers is easy: just press "Start" at the beginning of your ride and "Stop" when you arrive. During the ride, location services and motion sensors help accurately measure your distance. Don’t worry, your data remains completely anonymous, and we do not receive any geo-data from you. For those interested in diving deeper into data protection and tracking, more details are available. And by the way, no cheating allowed!
