Hi ofissa!

Welcome to OpenStreetMap! Nice to have you here trying to improve the data :-)

Changeset discussions enable us to ask why things were changed or give hints on how to improve the mapping.

Concerning this changeset, I wonder what's the basis of your change. Have you seen any "Zeichen 254" that explicitly forbids cycling? That's how it looks like:
https://de.m.wikipedia.org/wiki/Datei:Zeichen_254.svg

Or did you set "no bikes allowed" because the road seems too buisy for you to safely bike there?

Remember that we map the legal access restrictions, see:
https://wiki.openstreetmap.org/wiki/Key:access
"Access values pre-eminently describe legal permissions/restrictions and should follow ground truth, such as signage or legal ruling, and not involve guesswork. It does not describe common or typical use, even if the signage is generally ignored."
Furthermore and if I remember right, there is no signs near that road that forbid walking or horseriding. Mapillary supports that:

Note that (in contrast to USA?), in Germany, you are allowed to walk on the road even if there is no sidewalk.
For tagging if there is sidewalks or not, please refer to this wiki page:
https://wiki.openstreetmap.org/wiki/Key:sidewalk

Might it be that the intentions of several of your changesets would rather be correctly mapped with "use_sidepath"?

Lokking forward to your feedback.

Happy mapping!
