just eyeballing I would guess that the seat height would be approx 28 in. + or - 1. If your inseam is > 30 you should be good to go!
Awesome avatar pic, BTW! Offer 'em 50 bucks.
Thank you. I created that picture using Adobe Illustrator and Photoshop. It's sort of a quick-and-dirty version, but I plan to make a more accurate high-resolution one soon. I'll let you know.
