Any publicity for an electric motorcycle is good publicity for all electric motorcycles.
I first time I heard about an electric motorcycle was about 7 months ago, from a report about
Tony Helmholdt who was building his own. Since he wasn't in any position to start manufacturing e-bikes, I searched for others. The first e-bike that came up, with a lot of search results, was Zero. After searching a bit more, this other company, called "Brammo" started showing up. Having read about a number of bikes, I decided that Brammo was going to make the bike that I wanted to buy.
So, I would agree that Zero is doing a very good job of getting visibility. And to that I say, Great! The more people are made aware of the availability of e-bikes, the better for everyone.
