Electric Powered Trikkes  are also know as Ultra Light Vehicles.  While they are considerably lower cost than a Segway, they are not a cheap electric scooter, they are an ecco-friendly solution to the environment and are going to be the future of personal transportation. Their light weight and folding capabilities make them highly portable and easily transportated to the destination where they can be used.  Also called Tribreds, they are propelled by three methods: the electric motor in the front wheel, a combination of the electric motor and your body movements, or by your body movements alone.
