Abstract: The frame of the vehicle includes a forward section which provides a mounting for the front wheel and motor, a rear section for mounting the rear wheel, and an intermediate section extending between and connecting the other two sections. The intermediate frame section is elongated and lower than the front and rear frame sections so that the rider sits lower in the vehicle and with improved link angles, particularly at the hip and knee of the rider. A support module, mounted at the top of the rear frame section, is movable betweeen a forward position in which it provides upper back support for the rider, and a rear position in which it provides lower back support for a passenger. The seat for the passenger is located at the top of the rear frame section so that his head is well above the head of the rider when the vehicle is in use.
