If you have No hills on your ride, if you don't rapidly accelerate, you may get 18 miles per charge and that IF you plan on exhausting the battery. This is not advised if you plan of keeping the battery healthy long as possible.
I own a (dealer "new") 2011 XU and have had pretty serious problems. I bought it 2013. The Zero dealer and Zero took my motorcycle not long after i bought it, for more than two months out of our six month riding season to fix it, but that left me with no transportation and payments. Multiple XU owners have had bugs with that model's battery management system.
It is rough stopping dead in the middle of oncoming traffic or to have your motorcycle just die on you. Right now I'm dealing with sustained acceleration after backing off the 'accelerator' and constant jerking if I try to main a constant speed.
i sincerely doubt Zero or my dealer will quickly fix it or offer me a loan.
If you are committed to buying this bike at this price, get a separate in writing statement from the dealership stating they will buy it back to you at full price and interest if this bike has any of the above mentioned problems.
Zero told me if I could sell my 'new' bike after they fixed it, for $2,000.00, they MIGHT offer me the next upgrade at a slightly reduced price.
The dealer said it was the information Zero sent and wasn't their fault. Zero said it was the dealer who was responsible. Cool game, they both win and in my case I totally lose. If Zero only thinks a repaired dealer new bike is worth $2,000.00 that tells you something. Unlike Zero, I can't ethically justify selling this bike.
Better to go Brammo if you can swing it.
