Abstract

Bicycle design optimization for comfort, safety, and user experience is still a problem, especially for Southeast Asian riders, despite the fact that cycling is an environmentally friendly and effective form of transportation. This study fills this gap by using Finite Element Analysis (FEA) and Rapid Upper Limb Assessment (RULA) to analyse important parameters such as rider ergonomics, bio mechanical efficiency, and structural integrity. A comprehensive examination of the literature determines the problems of current designs with an emphasis on handlebar ergonomics, saddle position, and frame geometry. The methodology proposes an improved bicycle design that is optimized for local conditions by integrating survey findings with simulation-based evaluations. Key findings include a significant reduction in ergonomic risks, as evidenced by improved RULA scores (from 3 to 2), and enhanced structural performance, with maximum stress values reduced by 20% under critical loading conditions. These findings offer up possibilities for safer, more comfortable, and environmentally friendly riding solutions by proving that it is feasible to create bicycles that are specifically suited to Southeast Asian demands.
