My entire 30+ mile round trip last week cost about 30 cents. Even if I amortize the entire cost of the bike into my yearly trips (which is an absurdly fast amortization) ... it's still 1/5 the cost of driving. And that would be "I get a nice e-bike every year"
240Wh to fully recharge my battery after 14 miles of city riding. (335ft of total climb, no net elev. change) That's: 58 miles/kWh 94 km/kWh 1965 MPGe Or about 0.6 cents per mile at (higher than national average) Massachusetts electric rates.
