A designated mountain bike track is not that, it's a path specifically for bicycles. If mountain bike tracks should be tagged as highway=path, then the definition of path needs to be changed to not be an unspecified or mixed use path. > I agree, that this is not explicitly stated in the bicycle wiki page, and > should be added there, but I would assume that this is the common > understanding.
