Hi hein16,

I live in this area and I can't find any evidence to change this path to cycleway.

If so there should be a sign saying that this is dedicated cycleway with allowed pedestrians

https://wiki.openstreetmap.org/wiki/Tag:highway=cycleway

Also the path was tagged with 
bike=yes and foot=yes, as this indicate that both has access.

Can you describe for me why you changed this?

Best regards
