Kinda sick of absolute top speed discussions. This topic interests me a little more. Assuming we get a 5'7"(5'5" in reality) skinny guy on a super light weight bike, like a fuji feather, dropped down all aero, fiber glass fairings, you name it.

how fast you think? I'm thinking 32mph and that's on a perfectly flat test track.
 
The Solex is actually not even 1 HP (.87), I can actually get to 18-19 MPH on a flat at 180 lbs. A smaller china doll engine would be interesting for a really light build. My Zeda on the chrome molly Fuji is on 54 lbs all up. I imagine a good quality vintage road racer in the sub 20 lb range would make for a fast set-up.

I can get a light schwinn frame for free from a friend. I haven't decided if i want it yet.

A sub 50lb build isn't inconceivable. A stock fuji feather is around 22lbs. I want to say a stanton friction drive kit is sub 30 lbs being aluminum.

A light weight bike, 50cc engine, small plastic gas tank, alloy wheels, aluminum sprocket, and other lightweight parts could make a sub 50 lb bike. I think the enines are around 20 lbs.
