Vehicle operated by multiple power sources
First Claim
1. A tricycle vehicle comprised of a framework elongated upon a center axis between front and rear extremities, paired freely rotating front wheels equidistantly spaced about said axis, a single rear wheel vertically centered upon said axis and rotatable upon a horizontally oriented axle, a rechargeable storage battery, and seating means for a driver, said vehicle being propelled by power provided by a controlled combination of pedaling action by the driver, an internal combustion engine, and an electric hub motor having stator and rotor components associated with said axle, said power being conveyed to said rear wheel which thereby propels the vehicle.

Abstract
An economically operated low cost wheeled vehicle that accommodates a single driver occupant is propelled by power provided by a controllable combination of pedaling action of the driver, an internal combustion engine and an electric motor. The vehicle is elongated upon a center axis between a front extremity and a rear extremity having a single, axially centered wheel that drives the vehicle.

9. A vehicle which accommodates a seated driver and extends upon a longitudinal center axis between front and rear extremities of a rigid framework that secures a rear wheel centered upon said axis at said rear extremity and adapted to rotate upon a horizontally oriented axle equipped with an electric hub motor, and a powertrain comprised of:
-
a) a rechargeable storage battery which supplies electrical power to said motor, b) an electronic controller which, in a first mode of function regulates the amount of electrical power routed to said motor, and in a second mode of function causes the motor to produce braking of the vehicle with attendant generation of electricity which is fed to the battery, c) a pedaling mechanism operable by said driver to produce motive power, d) a gasoline engine which produces motive power, and e) a transmission system which accumulates the power from said pedaling mechanism and engine, and causes said accumulated power to drive said rear wheel to propel the vehicle. - View Dependent Claims (10)
