yeah, i'm so sick of all the people that are just now getting into bikes. all us old schoolers that have had bikes for 2 months and longer hate seeing newbies

seriously though, just get someone you know to let you learn on their bike. if i remember from masterbating to your pictures (j/k) you're pretty small, so i would recommend smaller than a 600 (or at least not a new 600). i'm 6'2" and have no problem putting both feet flat on the ground, but have a few shorter friends that ride and can barely keep both feet on the tippie toes. when i first learned, being taller definitely helped me from dropping the bike when i'd stop. just take it easy, respect the bike, and keep the rubber side down.
