FWIW my KR8 has a nexus 8 and I don't tend to feel like I've got too few gears unless I'm very heavily loaded on a steep hill. If I were buying it again I might stick a bigger sprocket on the back; I don't need to do more than evens on the flat, and downhill you can just let gravity do the work. An Alfine 11 would give a bigger range, and for what is after all a utility bike I like the lack of maintenance, ability to shift at the lights, and ability to run a chain guard.
