a door handle has a latch assembly which is arguably a wheel, as is the turning cylinder, if it has a lock it could have a bunch more “wheels” too, and the "rose’ (the round part that covers the hole the cylinder passes through to connect the two handles) could also be a “wheel” depending on your definition.
Not every cylinder is a wheel. Not every handle is connected to a door, and not every door has a handle. Sliding doors are doors, but not drawers. Cabinet doors are doors but not windows. A hinge is not a wheel. Plumbing isn’t a wheel. Your capillaries and glands are not wheels.
For the purposes of this question, I think the best definition is simply: a wheel is called a wheel, and a door is called a door. The definition is in the name. That basically eliminates most nonsense haha

One could count a hinge as a wheel as well.

Your definition is wheely bad
