what issues are there with a horizontal component to pedalling? Given that people manage to pedal recumbents
Pedal thrust on a recumbent is reacted by the back rest. On a conventional bike, the vertical component is reacted by gravity and the horizontal by saddle friction and arm tension. Since the load is cyclic and the gooch is flexible, the change in horizontal thrust at the saddle inevitably results in a certain amount of cyclic fore and aft relative motion between gooch and saddle, which is probably best minimised in the context of this discussion.

I guess that is true if you use or take into account KOPS. I set my amount of setback based on not having too much weight on my hands.
Other than respecting the god of KOPS, what issues are there with a horizontal component to pedalling? Given that people manage to pedal recumbents OK, it's not immediately obvious to me, but I might be missing something.
