摘要

Micro-mobility, like bicycles, e-scooters etc., is currently a significant global trend in cities’ transportation sector. Despite their growing popularity, these vehicles have been involved in numerous accidents, largely due to improper operation and inadequate safety precautions. This study presents a simulation model aimed at analysing the vertical dynamic response of a micro-mobility vehicle specifically, a bicycle both with and without suspension systems. The model incorporates the mechanical impedance of the rider, enabling an assessment of rider safety and potential risk. It comprises two core configurations: a base model without suspension, a model equipped with a traditional suspension system. Additionally, overviewed a one featuring of in-wheel suspension concept. The findings highlight the relevance of suspension systems for micro-mobility applications and provide essential insights for future enhancements, like in-wheel suspensions.
