Hallo,
Sorry, i will write it in english (just to be maybe clear).
I use maps.me, and sometimes it doesn't see any bike lines (if they are separate), so i have to use osm.wiki/Tag:google=) On all that places, which i corrected, it was separate bike lines on a sidewalks.
Now i see that on the bike-map - it's really a lot of bike lines (don't know about this map actually - that was a problem).
Other problem with crossing, i didn't find any good example on hamburg map - everywhere is different (same with bike-lines, example - Kennedybrücke and Lombardsbrücke).
So will try to use bicycle-map, and i will remove my corrections (hope this week)

Hallo,
mein fehler (osm-editor macht zu viel)
=)
