That wasn't the point I was making. I constantly ride hills because that's the terrain I live in (my typical rides are 5,000' and 50 miles and I recently completed the Death Ride [130 miles, 16,000']). However, as I move towards my sunset years I expect that pulling off such rides without power assist will become more and more difficult. I see no reason to curtail riding because of some silly purity argument regarding motor assist.
