Design and Fabrication of an Eco-Friendly Electric Go-Kart for Sustainable Transportation

Abstract

The increasing demand for sustainable and eco-friendly transportation has accelerated the development of electric vehicles (EVs) as an alternative to conventional internal combustion engine-based systems. This paper presents the design, fabrication, and performance analysis of a single-seater electric go-kart developed for low-speed urban mobility applications. The proposed system integrates a battery-powered electric drivetrain consisting of a 24 V brushless DC motor, lithium-ion battery, and chain drive transmission system.The design process focuses on achieving a balance between lightweight construction, structural strength, cost-effectiveness, and driver ergonomics. A chassis frame made of cast iron is developed and analyzed to withstand static and dynamic loads, ensuring safety and durability. Key subsystems including steering (Ackermann geometry), braking system, transmission mechanism, and electrical components are systematically designed and implemented. Analytical calculations were carried out to evaluate parameters such as turning radius, velocity ratio, and load-carrying capacity.The fabricated go-kart achieved a maximum speed of 20–25 km/h with a load capacity of approximately 95 kg, demonstrating its suitability for short-distance transportation. The study highlights the feasibility of developing low-cost electric mobility solutions with reduced environmental impact. The results indicate that the proposed design offers a reliable, efficient, and sustainable alternative for small-scale transportation and educational research applications. Future scope includes integration of renewable energy sources and advanced lightweight materials for enhanced performance.
