I got the 2011 zero XU for over 3 months already, I have ride it to work, grocery shopping, errands, or a short leisure ride after dinner. I find once you realize what the zero bike is and you will be very happy with it.
To me a zero is:
a commuter bike. - it takes you from point A to point B, recharge in point B, and ride back to point A.
It is also a perfect bike for short errand trip, you won't feel pain to ride a 8km distance to a grocery, buy some yogurt, and then another 8km home. You won't feel you waste so much gas just because all you want is to buy 1 orange.
It is good for a short ride around the neighbourhood. There is no noise to irritated your neighbour, and most of them will find the Zero is a cool bike.
A Zero is not:
A Touring bike. I will not ride my Zero to tour around the town, even if I know where is the electric plug.
Definite not for cross country.
If you like to mechanically upgrade and tweak your bike in every imaginable way you can, a zero is definite not your cup of tea. I own scooter before and I actually transform it from air-cool to liquid-cooling, but when I got a zero, all I can do is just some minor body mod. May be I am just not that good at electrical and software engineering.
So I receive good and bad comments on my XU, some laughs at the range, but some just find it so cool to ride on it. But as long as you know your range, purpose, and where you can recharge your bike, a Zero is definitely a fun and cool bike to have.
I love my Zero!!!
