I weigh in at 175lbs and I would consider myself an above average rider as far as strength goes. Pounding up a hill is something that is usually not a problem.
I understand the "tough comprimise" of just one gear, but for me thats the beauty of it. I love the simplicity of just one gear. I got so tired of trying to find the right gear all the time. Plus switching over to a SS took the weight of the bike down to around 15 or 16 pounds.
