Abstract—As modern culture and technology continue to develop, the growing presence of global warming and irreversible climate change draws increasing amounts of concern from the world’s population. Countries around the world are working to drastically optimize the use of fossil fuels, reduce CO2 emissions as well as other harmful environmental pollutants by advancing existing vehicular technology. By incorporating alternative energy drive-trains into vehicles that also use combustion engines, they allow for a slightly cleaner mode of transportation. The paper investigates the effect of externally loading the engine and hence shifting the fuel consumption curve to leanest air fuel ratio to obtain a better driving range. The mechanical design for this test was done in CATIA. The bike is powered by a single cylinder, 4 Stroke air-cooled 125cc conventional petrol engine and a 360W/15A geared DC Motor (Jack Erjavec and Jeff Arias, 2012). The bike’s design is chopper in nature with a high front rake angle. Motor gets its power from the batteries and drives the vehicle when the engine’s cut off, controlled by an electronic control unit. Our system enables approximately a 40% increase in the bike’s overall driving range, lesser air and noise pollution, enhanced comfort in city drive at low speeds and greater co-generative efficiency
