Hello.
Thank you for using Apple Support Communities. It sounds like you're experiencing issues with your right AirPod disconnecting or losing audio. If this is the case, we'd like to look into this with you.
To start, we'd like to ask some questions. When this issue occurs, does it only occur while riding your bike or does your AirPod also disconnect when using them indoors? If you connect your AirPods to a different device, does this specific issue continue to occur?
We would like to also recommend that you attempt to reset your AirPods. This step can sometimes help fix various issues. Please check out the following link:

Feel free to update us whenever you get a chance. Cheers.
