I've been riding around at 22mph average to see how much efficiency I can eek out. Today with zero pedaling I only used 1200mah for my commute to work. I had some small burst of speed here and there to get away from cars.
I installed a Cycle Analysis recently. It's a pretty fancy datalogger that plugs directly into my speed controller and reads out the voltage, speed, amp, watts, watt/h, etc. You can even hook it up to your pc with mods, which I don't think will do. But I can set the amp limit and voltage cutoff with a few presses of two buttons. Cool stuff.
