I'm new to these forums, but I've been lurking for a few days. I have to say - your bikes are just amazing! You've all given me the chopper bug!
Unfortunately I don't have the equipment (or probably the imagination!) to make my own, so I've been looking at manufactured ones. I've found one that I like, but its a single speed. There are many hills around here - most are pretty mild on my old road bike with gears, but I'm not sure how I'd go when riding a fairly heavy single speed bike. How hard would it be to change it from a single speed to either a 3 or 7 speed? Is it actually possible? Would I need any specialist tools?
Any thoughts you can give me on the matter would be appreciated!
