I'm 6'3", and about 450... I'm looking at getting a rover. Been talking to some folks and sounds like I'll need to do the wide seat and bars, can anyone tell me the width of the upgraded seat? Also, anyone around my weight been using one? What other upgrades are necessary right away?(wheels tires etc?) I've found one used about 1.5 hrs away and the close shop/dealer is about 2 hrs away. I don't want to have to buy brand new and upgrade a bunch, so was thinking of used to save a couple hundred, but could still easily go to $2k! Just trying to see if I'd have to do tires wheels right away. Mostly will be fairly good pavement in my neighborhood for awhile.
