Alright then, I've learned alot but I'd still like to know what I might start looking at specifically, were I to try and have a durable, yet lightweight tiny frame made. As I've said, considering how the thing is to be used, titanium is the material of choice. It'd be great if it folded, but at the very least it needs to have a folding handlebar set (something Dahon calls a handlepost). I would like a design where the wheels don't tuck under as I find that this is when grease arrives at clothing. My other desire is that the final product can withstand abuse and survive a minimum of 10 years daily riding.I suppose that means not so light that a dent will kill it. Probably 20 inch wheels; 451's seem right but 406's would do.

Whatever your thoughts I'll appreciate hearing them. Especially the custom builders who do this stuff so well.

Thanks,
