The girl rides a Breezer and the stock gearing is adequate... as she has gotten stronger as a rider she has found that every once in a while she'd like one more gear at the top but would not give up the low since she is always climbing hills and uses her bike for everything like shopping and towing her trailer.

When I am setting up bikes I find that a 40-100 gear inch range is more than adequate for most riders, my touring bikes have a slightly wider range with more bottom end, and for fixed gear and single speed riding I prefer a gearing in the low 70's.

My 3 speeds are always a bit of a compromise... will set them up so my main drive (2nd) is 65 gear inches which gives me a 40 low and a high in the low 80's.

One of my favourite bikes is a folder that has a 40 to 75 gear inch range with a 5 speed.
