Green Car Reports has a pretty good review of the Vectrix VX-1, Giving a pretty fare review of both its strong points and its flaws. With the plus that they have also reviewed the Zero and Brammo for comparison.

I wish they would have run them all to empty batteries from full at the same speed, so we could understand the ranges compared to each other, verses the marketing materiel range listed for each bike. Either way the review where well done.
And the Current Motor C124/C130, or even the ZEV, is not a "major electric two-wheeler"?
