We had this discussion Sunday. My brother, cousin, and I had just returned from a 30 mile ride, and the family picnic was in full swing. So I sat down and my aunt started asking questions. She's been known for some real doosies, so I knew something good was coming. Sure enough: "I don't get those numbers on the handles. What do they mean?" We tried explaining gears and how the ones on the left are for big changes, and the ones on the right are to fine-tune. "I don't want to do math while I'm riding! That's too much to think about!" I think that bike is marketed towards people like her.
