Thanks for great feedback. This type of cycleway is difficult in the Netherlands, since it is not allowed for e.g. horses, motor vehicles etc. 

I hope this is better, following https://community.openstreetmap.org/t/mofa-yes-of-designated-bij-g11-bord/109438 and https://wiki.openstreetmap.org/wiki/NL:Overzicht_Nederlandse_Verkeersborden:tagging_mofa_op_fietspaden

It is called a 'onverplicht fietspad'
