  • Arm-powered wheeled vehicle with bicycle-type cranks
    Patent number: 6070894
    Abstract: An arm-powered wheeled vehicle that supports a rider in a prone or kneeling position to use crank arms radially displaced by 180 degrees to influence rear propulsion. Using this rider positioning and crank system maximizes the relatively low power available from the human body. Further, providing two steering devices and a wide range of gears allows the use of this arm-powered vehicle for traveling over varied terrain with the greatest possible control and safety.
