CubeRootOfTrueBoundaries. What's a bike? What's a motorcycle? If you put fins on a cat does that make it a fish?*
This is an excellent example of how binary choice breaks. I'm an avid bicyclist and putting pedals on a machine like that to make it into a bike is, yes, like putting fins on a cat
* Technically the answer is yes, and there are many videos of cats swimming underwater. Also you are a fish
