Interesting stuff with respect to your Zero experiences. If I'd be forced to guess after my test ride I would have said 0-60 in around 8 secs which sounds like a good guess now.
The video gave me hope for a really good 0-60 time. I'm going to guess at around 4secs, say 4.3 for ordinary people and 3.9 for an expert.
More worried about the price but more excited about the bike!
