A guy in Oregon created a 3 wheeled electric, lite, electric vehicle, he calls "BugE".
Here a couple videos of it in action:

It appears to be chain driven, rear wheel drive. It appears there may, or may not, be suspension of any of the wheels. the shell canopy appears similar to the Go-One velomobile and others.
