Hello Everyone,
I kid has a pretty standard 20" fixed sprocket bike. We've been riding on very hilly terrain lately and I would like to add a couple of speeds (at lease 2 - max 5) and Im not sure how to proceed. Is it even worth it when I could go buy a whole new bike for under 100 bucks?

I can wrench the gear myself, Im just not sure what would be the appropriate parts.
