There is a large requirement for EV across the world mainly due to the depletion of fossil fuels. The next best option to conventional vehicles is the usage of Electric vehicles. The sudden transition from IC engine vehicles to electric vehicle can cause a major hike in sales of electric vehicles but this can also result in dumping of IC engine vehicles on a large scale. Retrofitting of the existing IC engine bike into an E-motor cycle and this is one of the solutions to avoid this disaster from happening. A study says that by 2030, the Indian government aims to convert 50% of the conventional vehicle into electric vehicles. The main purpose and goal of this project is to retrofit a conventional bike into an E-motorcycle. In the proposed work, the motor controller and converter parameters like output power, efficiency, power to weight ratio, torque, load, cost, aerodynamics, compactness, throttle response of the motor are determined.
