The world is advancing technically in the field of Engineering and Technology; it is never at a standstill. In recent time it has gained greater momentum than ever before. As demand for time increases, people require something less time consuming and fuel less as time is money, something more precise, something accurate, meaning something innovative which can serve the people comfortably. On this path, the science and engineering field is always under development and discoveries having come to the people and serves for their betterment and welfare. Electro-Mechanical power transmission or gearbox is a type of motor vehicle transmission that can run the vehicle using an external source instead of any fuel that can also change gear ratios as the vehicle moves. This change of gears takes place manually which are five speeds. In the coming intro, it clearly explains about the vehicle that totally runs on electro-mechanical power. Generally, electro-mechanical consists of BLDC motor powered by batteries which is an electrical part and a five-speed gearbox transmitting power via chain drive comes under mechanical. The mechanical gear box only consists of a clutch shaft with two driving and driven gear shafts connecting to the rear wheel of the vehicle helps to run. This moving of the vehicle takes place using the power source coming from the solar arrays used to generate electric power and to start the BLDC motor. The output of the batteries is controlled by the controllers and the motor is connected to the driving shaft of the gear box via chain. The power is transmitted from the driving gear shaft to the main gear shaft which drives the rear wheel of the vehicle via chain again. These transfers of power or motion take place under five-speed gear ratios operated manually for different speeds. To reduce the fossil fuel there is a requirement to adopt any alternative technique which can overcome fuels to be utilized, thus the technique using of solar arrays and making the vehicle to run on batteries with the help of the innovational power transmission gear box captured the fuels.
