Man, drop that 30t granny, get a 24t with Sturmey Archer CS-RF3 3 speed. Remember to breathe deeply when climbing on a trike. Breathe deeply, lay back as far as your seat will allow, gear down, and climb the hill.
Speed be cursed to the wind. Let the roadies have all the speed they want. I actually want to enjoy my ride uphill, stop and get video footage with my camera, not look at my chainrings all day.
