Well if i going to build custom then i need to know what exact size frame i need... I need something to go fast but be able to carry a few bags... and to move left to right pretty fast in order to dodge cars..

Where do you buy tubing? what tubing should i use? I live near salt water.. are there build kits? whats the best tubing?

I am 160 pounds, 5 foot 7.

tip of my in Dex finger to my shoulder blade is 26"

what else do i need to know? how do i figure out what size tubing do i need?
