What about the type that has bad knees, or metabolic issues, or low vision, or seizures, or about a hundred other things? Somehow I think a hard-to-see-in-traffic recumbent bicycle isn't going to be a solution for them. Advocacy is a wonderful thing, but when it turns into ableism it's disgusting.

I hear you. My uncle is disabled in the legs and I’ve admittedly had a hard time finding a recumbent arm bike that he felt comfortable enough to actually do his commuting on.
