I'll hold onto my 2012 for now, but in a couple of years I'll be taking a hard look at a new bike vs a used bike. New 2014 vs used 2013? New 2015 vs used 2014?
There are a handful of things that hurt the secondary electrics market:
1. Limited numbers of local buyers, and no centralized place to sell online.
2. Rapid improvements year-over-year. "What, your old bike doesn't have smartphone connectivity? How 2012!"
3. Lack of confidence in electric powertrain reliability.
4. Buyer interest in supporting the manufacturer by buying new and spurring further developments.
5. State or federal incentives which can dramatically cut the "real" price paid when new.
Zero has some options to address some of these .. perhaps primarily through their dealer market, which is still significantly in flux.
A certified pre-owned program would help #1 and #3, possibly #4 too. Combine this with a central dealer used inventory listing. Someone walking into the store may be drawn in by the $7995 XU 2.8, but turned off when they find they have to step up to the $10495 XU to get the range they want. "But what about this $5995 like-new 2011 S? I can have it here Thursday."
Providing an (optional?) long powertrain warranty should cost Zero very little. They talk of hundreds of thousands of miles of lifetime on the battery but only offer a 2 year extended warranty. A long warranty would help #3 significantly - and the BMS collects enough information to be able to offer a reasonable estimate on how gently the battery has been treated.
Loyalty rebates would help #2, but hurt #5.
I'm increasingly of the opinion that "alternative powertrain" incentive money would be far better spent at the state and federal level building up a charging infrastructure rather than offering fleeting purchase rebates. Unfortunately, there's still a lot of bitter fighting ahead of us with respect to charging standards, and this hurts any rollout plans. J1772 level 2 is pretty entrenched (new rollouts should supply AT LEAST 30A), but wireless charging may become more prominent in several years. CHAdeMO and J1772 level 3 DC charging have a tough fight ahead of them.. and in the short term at least, EV owners will suffer.
