Design, Simulation, and optimization of a four-wheel electric bike

Abstract

The use of bicycles as an alternative mode of transportation has seen a significant increase, with cargo transport by bike becoming more attractive. This trend is mainly due to bicycles' considerable environmental benefits, including reduced carbon emissions and low operating costs. Amid growing global concerns about environmental sustainability and urban traffic, bikes have become a practical and eco-friendly solution for short-range logistics and small-scale transport, offering hope for a greener future. This thesis presents a detailed study of the design, simulation, and optimization of a fourwheel electric bike aimed at promoting sustainable transportation. The research addresses critical design challenges and proposes solutions to improve the stability, functionality, and performance of cargo bikes for urban logistics. A comprehensive literature review examines geometry, loading parameters, frame design, aerodynamics, suspension systems, and steering mechanisms, highlighting environmental benefits and adoption barriers. The methodology involves modeling, design adaptation, and iterative optimization using Simscape Multibody to evaluate dynamic performance. Detailed component models were developed for the bike’s chassis, joints, steering system, power transmission, suspension system, braking system, and rider. Simulations tested stability and functionality in various operational scenarios, leading to an optimal configuration with adjusted front wheel positions, joint specifications, and specific suspension settings. The findings of this research show significant improvements in stability, performance, and control, providing practical insights for manufacturers. This research supports ecofriendly urban mobility, contributing to efficient and sustainable transportation solutions.
