I test drove one last year. Incredible acceleration, very smooth. The lack of routine maintenance is intriguing.

Unfortunately, I found the bike uncomfortable after just 10 minutes. The bike places the rider leaning forward with weight on the hands. I found that quite uncomfortable after just a few minutes and found the overall frame size to be too small. If they came out with a larger frame with more of a sitting instead of forward leaning position I would not hesitate to buy. That said, I think their milages ranges are unrealistic for high speed riding. I fear though that the cost of replacing the batteries when worn will be quite high.
