Anspachlaan has a  F103 with additional sing for cyclist and tagged with bicylce=yes https://www.openstreetmap.org/way/356328305#map=17/50.85002/4.35621 (for the area) and https://www.openstreetmap.org/way/12351894 (for the street itself). 

Here we have a F12a  thats indicate other restriction and rules and all the zone is tagged as pedestrian without allowing bicylcle to pass true. We can argue that theres some bollards blocking the zone and making this "defacto" a pedestrian zone, but it's not conform to signs and if at least cyclist should be allowed , that not the case in recent or old changeset  and it's not conform to the ground.
