Thanks for the note. The road that your note is on is also rideable in OSM, but the parts just northeast of it (here: https://www.openstreetmap.org/way/120147928/history#map=19/40.05226/8.86360) behind the gate are marked as "private access only"/private property, so those are probably (correctly) shown as non-rideable in Komoot.

So nothing to change here, I think. If you find other spots that need adjusting, it's good to open notes like this though. Or even better, you could make an account and do the changes yourself, here's some info for starters: https://learnosm.org/

Enjoy and all the best,
