hang in there. i commute 26 miles 5 days a week, and am 6'3'' 275 pounds, so i know where you are coming from! one of my favorite things to do is catch up to whoever yells at me, and pull right up on top of them, then stand up and give them a "look" I guess i look allot smaller when i am bent over the bike! scares the S@%$ out of the little punks every time when i get up close and personal
