Abstract: A three-wheeled vehicle is provided to operate from a source of power constituted by two batteries which constitute approximately one-third of the weight of the unloaded vehicle. The batteries are so positioned as to locate the center of gravity of the vehicle relatively low. The vehicle is provided with a superstructure which is relatively light so that the center of the gravity is not greatly affected thereby. The superstructure provides protection for the passenger or passengers who are sheltered thereby. The passengers are seated at a relatively high position relative to the ground traversed so that they obtain a feeling of security and confidence and can readily see because their relatively high position with respect to other vehicles or obstacles in the vicinity. The additional weight of the batteries is accommodated by the provision of a compound braking system consisting of mechanical and electro-magnetic braking elements.
