I've got 28K miles on my Empulse and, except for early warranty work (redesigned flimsy taillight section and a bad transmission seal), I've had no problems of an EV nature. I recently had to replace the steering head bearings after an infamous SF pothole brinelled them.
I'm on Time-of-Use rates with PGE and charge my bike with a timer while I sleep at 10 cents per kWh. Cost works out to roughly 1 cent per mile. So my fuel cost for 28,000 miles over two years is $280, or about $12 per month, or half a tank of gas in my wife's Prius. I don't at all miss dealing with plugs, valve adjustments, filters etc.
Insurance is about the same as my last gasser.
Yes, it has a tranny, but I don't use the clutch for upshifts, leave it in 2nd gear around down, and don't use the clutch for stopping and starting (the motor doesn't turn at standstill). So my 71-year-old clutch hand is happy.
Can't imagine a better commuter, unless it were a Zero, but then I LOVE the Brembo brakes, super tight frame with Street Triple geometry, and solid suspension of the Empulse.
