I have a Schwinn Willy (single speed).
My commute is 6 miles each way on flat road with a bike section. There's only one 'hilly' section. A single speed bike is too slow. Everyone keeps passing me. I need gears.
I don't want to spend money on a new bike since I like my current one so much. I thought I can upgrade it to have gears using a Shimano Nexus 3 internal gear hub.
My understanding is that I can fit it in. I can even mount the cable through to the steering bar. But I can't find anything on how to install it into the wheel itself. So my questions are:
- Will it fit?
- Do I need new spokes? If so, what size? I can't figure out what size my wheels are. They measure 27.5" including the tires.
- The hub only gives 33% boost in gear. If I want more than that can I put in a new crankset? What size? I can't figure out what size I have and what's bigger than that.
