Re: What would you build?
Pretty much what I'm building right now. I've already lost track on how much I've spent but it's gotta be right around $1,000 so far and I'm not quite done.
Chopped Schwinn OCC Stingray, a nice peanut tank, real motorbike bars, risers, hand controls and rear tire, hydraulic bicycle front brake, outrageous blingy front wheel and a china-girl 66cc engine. The only thing I would have done different is instead of modifying the unsprung forks I bought is I would have bought a nice set of springer forks from choppersus.com.
*edit* and I don't think building a motorized bicycle classifies as a mid-life crisis. You're not picking up any broads with a motorized bicycle. That's what Corvettes and Harleys are for.
