Re: What I found while cleaning out the garage.
I agree! Very cool little bike there! As a 6 foot fat man, I would suggest a sprung banana seat as well. The bars would be an individual choice but I'd try some bmx style medium rise for something similar to a Jesse James chopper riding position. You gain legroom by sliding back and don't need as much height.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
