I have not looked -- does the fuel log do the MPGe calculation; or what conversion factor are you using?

34.02 KWH/Gal per wikipedia, and I'm measuring KWH at the wall with a kill-a-watt.

Another measured value from this trip: 33.6 wh/mi at the controller.

1,267 miles on the odometer after the first two months of commuting, 4 days a week. I love not driving my car!

Suprising 5 mph cuts your mpg-e almost in half.

Yeah, the aero drag goes up... exponentially Bikes actually have a fairly high CdA, so making them go fast becomes a challenge, unless you want to go with a recumbent and/or fairing.

Edit - oh yeah, I've been using a different charger power supply lately, and if I leave it on all night, the fans keep running. So the charger efficiency has dropped from 67% to 53%.

That's why the MPG-E curve is steeper than the WH/Mi curve. I measure MPG-E at the wall, and WH/Mi at the controller.
