Great post - thanks for sharing your thoughts. In a nutshell, if you’re going to buy an electric bike then regardless of how hard it is for some of us to accept, we have to grasp the fact that we're buying an electric bike because of our interest in electric and not for the fact that you’re going to make any impression on air quality or saving the planet, so let's leave out all the political crap that's circulating about global warming because our contributions mean almost nothing when looking at the big picture. With comparing the current low cost of gasoline, to the high electric cost in some states, it actually cost more to charge your bike with electric than a comparison cost of a gas bike. Next, throw in the the new gas tax and we’re paying much more than our Ice powered bikes.
As you outlined - you really have to want an electric bike to buy a Zero for the plain fact they deathly expensive in comparison to an Ice bike. Bottom line the most important thing is that your happy with your purchase, if you’re happy and can afford to pay the price then you’re good to go!
