So, pinaz - just out of curiosity, are you currently riding an electric motorcycle? If so, what brand and model? I'm jumping in with a good deal (I hope!) on a clean 2011 Zero S because I have to start somewhere. I've watched this scene for years, ridden several prototypes and conversions, marvelled at the high asking price for ALL of the possible choices. I'd be eager to hear suggestions ......
I have a 2011 Zero XU that I bought new (one of the two model year old leftovers that no one wants) and made the same leap as you appear to be set to.
I thought (naively, with hindsight) that it would be maintainable because it was using off-the-shelf components. I bought it unseen out-of-state because there was no Zero dealer within 700 miles.
What I found was exceptionally bad engineering on Zero's part (to the point where I, as an engineer, would feel uncomfortable with). Zero makes itself a middleman to do anything, and they really don't care to support their product (despite claims, at the time, otherwise).
From the propaganda I hear through the Zero dealer, I think Zero's funders are now positioning it as a motorcycle (secret sauce) battery company. They know that they can't build motorcycles. I assume the companies with the engineering to make motorcycles are waiting for someone else in the market to commoditize battery prices.
So, BrianTRice's point about eyes open and riding the hell out of it to get your money's worth is valid. My added caveat would be that you have only two years or so from the model year where you can hope to get any cooperation from Zero (and still be ready for it to be offline for weeks, so it is not practical as a sole vehicle). At the end of that two year period, be ready to throw the bike away for nothing.
