Upvoting for importance in this debate: You can't count a wheel twice if it has wheels nested inside of it

A wheel needs an axle, so the bearings aren’t a separate wheel, but part of the larger wheel.

So if you take the wheels off the bicycle, are we no longer counting them as wheels?

Also, bearings have inner and outer races, so technically, the inner race could be considered an axel.

In the same vain, I think doors need atleast a frame and a large sheet of some kind to close it.

I think this definition of "door" is probably too restricted at the same time. When I moved into my house, I had to take some doors off to get the furniture in. The doors are still in the basement. My wife sometimes asks me what we are going to do with the doors in the basement. If someone was down there, they would recognize them as doors that have been removed. By your definition, those doors aren't doors. As the same time, the lid on a dumpster meets the definition of a door, so maybe the definition you have is too expansive?

The point is, the question is confusing because wheels are doors are concepts that we have, and not strictly defined objects.
