In recent years, micro-mobility usage, such as electric bikes and electric scooters, has become increasingly popular as a mode of transport in many countries due to the introduction of shared services. Electric micro-mobility vehicles are environmentally friendly, provide efficient solutions for last-mile trips, and link to major transit stations. However, due to their new establishment , the regulatory framework governing micro-mobility vehicles varies across different countries, and they have undergone several changes over the years. While micro-mobility vehicles offer substitution benefits to individuals, the safety concern regarding these vehicles remains controversial. This thesis aims to analyze the existence of the regulatory framework governing micro-mobility vehicles, particularly electric scooters and e-bikes, in terms of technical specifications, the use of infrastructure, and homologation requirements in Belgium, France, and Germany.
