A biwheel vehicle has large left and right main wheels 1 supported by suspension assemblies 7 acting between rims of each main wheel and a payload carrying cockpit suspended above the ground between the wheels. The arrangement facilitates access to the cockpit payload space through the wheels. Each wheel may be cambered to deter pitching motion of the cockpit within the wheel. A rear jockey wheel 61 may be provided to further deter pitching. Propulsion to the wheels may be via electric motors built into drive wheels 16 which are mounted onto a suspension assembly 7. The torque applied can be controlled by a digital control system responsive to sensors such as a cockpit attitude sensor, to further deter pitching motion of the cockpit. Propulsion may additionally be delivered by a manual propulsion system supplemented by the electric motors.
