There is a cycling subculture, but it, like all other subcultures, is wrong when it sees itself in isolation. I also think the easy mental picture to see when thinking about belonging to a subculture is to see yourself as belonging to a club, and others dont belong to a club.
We all belong to many subcultures.
Everybody is a collection of their subcultures, and maybe after deconstructing a person into their subculture components, there is nothing left over
