Hi guys. I'm looking at an old Raleigh Twenty this afternoon and was hoping you guys can help me out. I'm a fatty (6'3", 280) and everything about a folding bike doesn't seem right for me

. I'm changing my location soon to a mass transit-friendly area and a folding bike would be a great help. I know I'll have to make some modifications to it due to my height, but will my weight be that huge of an issue? Pardon my ignorance, and thanks for the help!
