Place I bought my Zero from dropped Zero from their lineup after Zero took nearly a month to send a charger to them - and we're in the United States. Zero failed them a few times they said. Sucks for me, as I have a heavily flawed bike (at the time, it just shut down randomly while I rode it) and no place nearby to get it worked on.
A new dealership opened, a bit of a ways away. They did unauthorized work, didn't fix anything, charged me for it, damaged my bike and said it was like that when I dropped it off. I told Zero I didn't want to work with them anymore, they were dishonest, and Zero forwarded my E-mail to the dealer and told us to work it out!
My $16,000+ bike is at a third dealership now, having the original problems looked at, plus new serious issues. Zero won't reply to my E-mails. My warranty runs out in a few months now, the bike is approaching 3 months in the shop, with no loaner bike and me having to pay $18/day to park my car, vs free motorcycle parking...I've reported them to the BBB, and I may have to go to a lawyer next. I'm not paying for a fourth visit out of pocket.
Love the product, when it works. Hate the company, their customer services is truly horrifying.
