Sorry for the late reply. Actually, I'm talking about the guy who built a
flevo clone and put a delta rear end on it with a horizontal pivot so he
could still lean into corners like a normal bike. I'm wondering if it's
necessary. I've been following Greg's since almost the beginning, but it's
a little too complicated for my likes :)
