I started to design a 3 wheel electric vehicle just for my entertainment about 6 years ago. Two wheels at the front, and one at the rear, but just didn't have time to go further with it. I think I remember talking to Alex about it when he came out with his AWESOME 3 wheel vehicle concept.
A good friend of mine Bill Mills (from Warpig fame) built an electric motorcycle and if I ever get spare time in my life again (lol) I would like to do that.
For me an electric vehicle makes sense because 99% of my journey's are 10 miles or less. I don't want a leaf or prius though. I want something FUN!
