I was getting 25 miles out of about a kWh on my Organic Transit ELF, which back up your estimate. That is 40kW/mile. It has bodywork, and weighs about 450lb with my in it and a bit of gear. TOp speed was an average of 24 mph for an hour - that is working hard at the pedals. If I would slack off o

It is primarily about speed and drag coefficient - not that it is a motorcycle or a car. An unfaired motorcycle is in the same neighborhood of drag as a blocky car. I had a BMW R75/5 and it got maybe 45mpg, maybe 50 mpg. Considering the difference in weight, rolling resistance, the car is pretty
