I was just riding along on the Hercules this afternoon, about five miles into the trip, when suddenly the hub started dragging a little bit, and suddenly... I had second gear.
About ten miles later - so after about fifty total miles, two weeks, and probably six tablespoons of 20-weight oil - it consistently has all three gears. Yay for British engineering.
And about five miles after that it started to rain, whereupon the coaster speed attenuator actually proved marginally useful.
