Somewhat newbish question: Any way to make a single-speed multi-speed?
Right, so, long story short, right now my bike of choice is a single-speed cruiser. Turns out my area has more hills than I thought when I bought the thing(sidenote: Don't do all your test riding in a perfectly level parking lot if you can help it). While money isn't super tight or anything, I really like the bike aside from the single-speed thing, and thus would rather not have to set it aside and get a whole new bike just to get some gear-shifting going on.
So I ask you guys. Do I have any options if I want to convert a single-speed bike into a multi-speed one? Or does it only go the one direction?
Thanks, guys.
