Try as I might, I can't shift my inner snob, so I offer the following:
There are cyclists, and Cyclists. Within the former category, there are all people on bikes, but they are sub-divided into numpties and ordinary cyclists. Numpties are the no-lights, rlj, hoping on and off the pavement sort, whatever bike they ride. Ordinary cyclists are the rest, the ones who ride in an appropriate manner in the appropriate place (road or cycle path, depending on convenience and safety, but not on pavements, unless officially shared). Obviously, I'm in the second group.
Then there are Cyclists. These are a subgroup of Ordinary cyclists. They are the people who define themselves by their cycling. So not those who just use a bike to get about, and don't really mind much what sort it is, as long as it works, but those of us (and yes, I'm in this subgroup) who understand n+1, and that bikes can have different specialities, and who go on holiday on their bikes, and cycle for fun - but serious fun. People who see bikes as more than just transport - although they are transport as well of course.
The edges of these groups are fuzzy of course, as is all human classification. And people can move from one group to another, if they choose to.
