Design and Fabrication of Electric Bicycle with Regenerative System

The increasing demand for sustainable and efficient transportation has led to the development of electric bicycles (ebikes) as an alternative to traditional modes of transport. This paper presents the design and fabrication of an electric bicycle integrated with a regenerative system aimed at enhancing energy efficiency and extending battery life. The proposed system utilizes a brushless DC motor to drive the bicycle and a regenerative mechanism that recovers energy, converting kinetic energy back into electrical energy. The design considerations include optimal motor selection, battery management, and regenerative circuitry. A prototype was developed to demonstrate the functionality of the regenerative system, and experimental results show a notable improvement in energy conservation, extending the operational range of the bicycle. The integration of the regenerative system also contributes to reducing the frequency of battery recharges, offering an environmentally friendly solution for urban transportation. The paper concludes with an analysis of the system's performance, highlighting the potential benefits and challenges of integrating regenerative technologies into electric bicycles.
