I have a 5 speed IGH. Commute is 12-18 miles round trip. A few 4-8% hills but none longer than ~ 0.5 miles. I rarely use first or fifth gear and frequently wish I bought a 3 speed hub. I frequently ride a local Rails to Trails route (60 miles round trip) on either this bike or one with a 2 speed IGH. The grades are gentler and so I can't imagine needing a bunch of gears. It's curious to hear my companions with their many, many gears constantly shifting up and down. Sounds like a lot of stress I don't need.
