NOVELTY - The vehicle has a battery (120) that is provided within a vehicle frame to store energy. A pedal generator system is provided with pedals to interface with a user. A generator is configured to generate current for charging the battery. The pedal generator system is configured to provide a variable resistance at the pedals. A motor (102) is connected to the battery to propel the wheeled vehicle. A steering system is configured to steer the wheeled vehicle. A computing system is attached to wheeled vehicle and configured to provide user with a selection of two program modes.    USE - Wheeled vehicle such as variable resistance serial hybrid electric bicycle for providing exercise for user (all claimed).    ADVANTAGE - The user is enabled to change the configuration of the front suspension from the first position to the second position, thus the vehicle stability is enhanced and the area occupied by the vehicle is minimized. Since the motor is placed in the wheel hub to increase the efficiency, thus the space is saved and the complexity is reduced by utilizing a smaller number of moving components. Since the regenerative braking feature is fully programmed and adjusted from little or no regenerative braking, the vehicle is enabled to coast to maximum braking and thus the vehicle is slowed very quickly. The user is enabled to dynamically adjust the feel of resistance at the pedals based on an arbitrary workout profile independent of varying load on the main battery. The electronically controlled variable resistance recharging system and the double reduction, dual generator systems are provided to enable the vehicle and rider to vary the resistance, send all the power that the person generates to the batteries and generate enough power, thus the rider is enabled to contribute to the battery effectively.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of operating a wheeled vehicle.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the variable resistance serial hybrid electric bicycle.
