Hi, could you please specify, why bicycles are forbidden on this part of Strakonická Street. I didn't found any signs that claims that.
Or this part which you also edited (https://www.openstreetmap.org/way/40759221)?

It's not a highway (in words of OSM - motorway), just a 4 laned road. So bicycles are allowed there (if there is no sign).
Regards
