I just bought an Avenir folding bike from ebay for $120 for a bad weather back up bike, I believe this is a Dahon rebrand for Raleigh. It's a single speed and I want to convert it to a 5 or 8 speed internal hub or a 7 or 8 speed casette. Does anybody know what the best option would be for this or if it is even possible?
Here's the pics:
I'm a little concerned regarding the rear wheel set up. Will it even be possible to fit a casette in there or should I just go with an internal hub shifter?
