Hi Matheus,

you added "bicycle=designated" to way https://www.openstreetmap.org/way/1301965616 here. Are you sure about that? I removed the designated-tag, because I'm pretty sure one do not have to use the cyclepath here (s. also quite up-to-date Mapillary imagery https://www.mapillary.com/app/?pKey=409371385328438). But I'm happy to re-add it if I'm wrong.

For cycleways, it requires one of three signs (number 237, 240 or 241 as shown here https://wiki.openstreetmap.org/wiki/DE:Tag:bicycle%3Ddesignated) so that a cycleway _must_ be used by cyclists. Colored paving stones on the sidewalk have actually no legal meaning in Germany. On a road/street, colored cycle tracks, however, do have a legal meaning. It's all quite complex ...

Cheers
Hauke
