What has been happening with the rapid advances in performance with e-motorcycles is that even though you might take a hit by selling or trading-in your 1,2, or 3 year-old electric bike, the new specs are so spectacularly better that you bite the bullet anyway. Would you really want a 2010 Zero now?? Realistically you can't look at an electric motorcycle as an investment compared to ICE bikes like say a Ninja 300 or a BV350 or other higher mileage, relatively low-priced ICE where you can buy 2-3 of them including maintenance and gas and still be ahead. A 3-year service contract on my Gixxer 1000 was $1549, that includes all the oil changes, valve adjustments, spark plugs, etc, so the difference is fuel cause a new 2013 Gixxer costs about the same as the 2013 8.5 model S. I think resale value of the Gixxer will be better, but at least those two bikes might match up to be similar in costs. Performance is something else again. Clearly the Gixxer outperforms the Zero. However, for many people the Zero is an almost perfect bike because of the convenience of not having to fuel up, cheaper fuel, light weight, plenty fast enough, and more than enough range for them. You just have to look at what's important to you and really it is hard to put a price tag on that. There are better investments than an electric motorcycle for commuting and worse, but that seldom turns out to be very important. Not many people only have a car, and for those who do have a car, adding a motorcycle doesn't save you money, so right off the bat you are not making a good investment when buying a bike, any bike, so these arguments are mostly trying to somehow justify your (over) spending. I don't even try, having spent just under $100,000 on motorcyles the past 3 years.
