That's seems really expensive, when my car at 35mpg and $2 gas a while ago cost 6 cents per mile. An ebike should be wayyy cheap than 1/3rd the cost per mile of a car, even when gas was cheap.
At 20watt hour/mile it should be something like:
400watt/hr / .8 charger efficiency = 1/2 kwh for 20 miles. at 30 cents/kwh, that's 15cents/20mile or 1.33 cents per mile. But if you ride fast, 2 cents per mile could happen. The thing is, everywhere I've lived power is around 10-11 cents/kwh. So it's 1/3rd that cost.
Can't trust me, huh? I wanted to save myself the trouble but here goes:
My last ConEd bill is/was $58.96 for 184 kWh. So my post was incorrect - it's actually 32 cents per kWh. Of course, they hide it using Supply charges, Delivery Charges, Surcharges, SBC/RPS charges, sales tax, etc. Would you like to see the bill? Total electricity charges = $58.96, Electricity used = 184 kWh
My usual commute is almost exactly 8 miles round trip. My batteries need roughly 333Wh from the charger after a typical commute. My charger's connected to a Kill-A-Watt meter and measures almost exactly 500Wh per charge cycle. Basically using .5kWh from the AC outlet to power myself for 8 miles. 1/2 of a 32 cent kWh = 16 cents. 16 divide by 8 = 2 cents/mile.
Just because you may not have experienced insane electricity prices doesn't mean it's not true...
