You're implying that upright riders can't spin? Your note about not standing acknowledges that NOT spinning is even more detrimental to us than it is to upright riders; but that doesn't mean they can't spin, too.
Put simply, recumbents are no easier on knees than uprights, and are potentially worse if you're not using good form.
