I just got back from a 25+ mile ride around town and the bike seems to be a screamer at top speed. The 47 tooth sprocket still gives her good low and mid but top speed is a little fast (around mid to high 40's.) I'm having Andrew make me a 52 for around the town use and a 58 for racing. Tommarrow I'll take picture of the bike when I get home from work. I have no regrets on picking the 5.8hp. It's a little louder than the 3 hp but still quiet enough for the neighborhood.
