If "foot cycling" is in the Olympics, why not hand cycling? If propelling yourself around a track or along a road by transferring power from your legs to wheels is one of the 39 disciplines, why isn't doing similar with your arms?

Look at it this way: if a world-class cyclist were to lose, say, a lower arm, but, with a prothesis, could still operate the handlebars, would they nonetheless have to start competing as a Paralympian? And if so, then why?
