motorcycle as alternate hybrid vehicles

Many manufacturers are using motorcycles as a base upon which to build hybrid or alternative vehicle choices to replace the cars that clog our highways and guzzle gas. Aptera, BMW, Cirbin and Carver are just a few of the companies that have such that are being designed or in production. Some appear to be standard 3 wheelers with one wheel in front and two in the rear. Others such as Aptera and Cirbin place two wheels in front and one in the rear.
What I find really interesting is how some of the companies have dealt with the problem of one of the rear wheels lifting off of the ground when running at speed. The Carver for example uses computer controlled hydraulics to "lean" into the corner, just like a two-wheeler. Neat huh!
