First voyage out the battery lasted 11.1 miles with pedaling. The kill-a-watt says the charger and battery took .35KWH according to my math that is 31.5 watts per mile. I have no idea if that is good. I didn't have the watts up meter for the maiden voyage so next time should be interesting.
I figure if I had to buy an equivalent amount of fuel to go 11.1 miles with a gallon of gasoline at $3.699 and a KWH at $0.062...(Duke charges 6.2 cents per KWH over 1000 KWH...)
(.35KWH X $0.062KWH) = $0.0217 is the amount to charge battery...
($0.0217 kwh / $3.699 gal) = 0.006 gal amount of fuel I could buy with $0.0455
(11.1 miles / 0.006 gal) = 1850 MPGe
I know NiMH batteries need a period of time and cycles to run in... so range should improve. I think my 50 mile range is a pipe dream with what I have. I would have to pedal more than half of the distance with a 20Ah battery.
That said it is sufficient for running a few errands... I rode around for a little over an hour... plus I did use assist almost the whole time. The top speed on flat ground is 26 MPH throttle pegged.
