We had a demo of the Zero motorcycle. Very slick engineering. On the edge. 10k. Electricmotorsport does about the same thing with off the shelf components for less money & achieves similar performance. 60 mile range & maybe better acceleration. Both are better performing than the Vectrix. However these are apples & oranges bikes. The Vectrix is a bit more money but I suspect the battery pack will last longer. Lawrence Rhodes.
