However, bicycles evolved to be ridden by humans. Even on a personal level. My old steel road bike, modified extensively, now has a very short handlebar stem and compact handlebar. This happens to bring the modern brake/shift levers into a position where I can keep my hands on "the hoods" for many hours without having to switch hand positions to elsewhere on the handelbar for relief. Looks a bit weird, but works for me. There's a reason the classic diamond frame bike has survived for 130+ years. People constantly invent better bikes but none of them ever seem to go anywhere, except of course recumbents and folding bikes, which really are better for a tiny fraction of cyclists. I'll bet they, too, have reached a pinnacle of evolution.
