MTB-Scale

[pqhf5kd]

The CSS style for MTB-Scale is currently:
.bicycle-yes.surface-gravel, .bicycle-yes.surface-dirt, .bicycle-yes.surface-grass, .highway-cycleway.surface-gravel, .highway-track.bicycle-yes

I suggest adding the following tags:
.bicycle-designated.surface-gravel, .bicycle-designated.surface-dirt, .bicycle-designated.surface-grass, .highway-track.bicycle-designated

And possibly:
.bicycle-designated.surface-unpaved, .bicycle-yes.surface-unpaved
The definition of unpaved on the OSM wiki is vague and it is recommend to use a more precise tag:

A feature that is predominantly unsealed (unpaved); i.e., it has a loose covering ranging from compacted stone chippings to earth. Unpaved roads may, in aerial imagery, show evidence of water along their course; in such circumstances, the waterway should not be tagged as a stream, though it might appear as such. This value gives only a rough description; use a more precise value if possible.
