Ok, so I have tried to figure out my efficiency but decided it isn't really an easy question. First, I just figured out my range. Holding my speed down to 20 MPH and always peddling, I got 73.3 miles out of my theoretical 23.4 amp-hour 48V battery. That number is a good one for me to know...

Arrgh, it is now so hard to limit my riding to 20 mph for the efficiency test. I have gotten used to 30. How am I ever going to go back to a regular bike, where I used to feel good when I could average 14?

I just ordered a cheap Watt meter off ebay - I wasn't ready to spend 10% of my costs on a Cycle Analyst. I won't be able to place the meter well but perhaps I can see it if I hook it to my seat below my right arm.

Thanks! I have gotten back and forth to work three times on one charge, about 52 miles, without any particular care. The power gauge was low but it is just a series of bars and I don't know exactly how close I was to running out of power. Over the course of the next few days I will try to...

Thanks. It seems they automatically change the winding depending on the rim size. They quote a speed of 42.7 mph for a 29 inch rim, which is about 495 rpm. They quote a speed of 45 for a 26 inch rim, which is about 580 rpm. They quote 43.3 mph for my 20 inch rim, which is about 730 rpm. I...
