Frank had a problem with the hamster bars on his Optima Baron - they hurt his wrists. So for improved ergonomics, he flipped them! And then, to rest his hands a bit, he added bottom grips (wrapped bar ends). And now we have what is likely the first ever recumbent "butterfly" bar configuration.
Yes, there are "butterfly" bars on upright bikes, but do theirs have distinct upper/lower wings and brake lever antennae? Didn't think so.
