Jack Rickard has several episodes on the 2 Beck conversions he's done. I've seen them on youtube, as well as EVTV. The Harvest Beige car comes back here so we can make some molds of the battery boxes and such for an easier and more "factory" conversion the next time.
Likewise, ECO Classic cars has done one conversion and is working on their 2nd now. There is a link on my site to some photos of the install. Click on electric conversions tab.
There are also some photos of a spyder done by Duane Ball, a customer of mine in NY. Fantastic job.
I spent several days in Colorado a few weeks ago, and drove the EV speedster for the first time. I guess I am torn. Performance was great, pulled HARD off the line, and better balance than the gasoline version. Regenerative braking takes a bit to get used to, as soon as you lift, the car slows like you are on the brakes. The biggest hurdle for me is the noise (or lack of). 80mph and all you have is some wind noise and the sounds of the rubber on the pavement. Kinda strange for me...
