Micromobility is rapidly reshaping urban mobility by transforming travel behaviour, urban space, and transport systems. Its growing role in reducing car dependency and supporting low-carbon mobility has positioned cycling, e-scooters, and e-bikes as key components of sustainable urban transport. The aim of the study is to investigate how micromobility is reshaping urban mobility, particularly travel behaviour, urban mobility policy, urban infrastructure, and public transport integration. This study employs a systematic literature review (SLR) to provide a structured and transparent framework for synthesising existing research, identifying trends, and mapping knowledge gaps across multiple dimensions of urban mobility[MO1.1]. It combines inductive and deductive reasoning to ensure the review is both theoretically grounded and responsive to emerging patterns in the literature. The findings reveal that the most impactful areas of micromobility development are demand and changes in travel patterns, environmental performance and urban decarbonisation, road safety and user perception, policy and governance capacity, and public transport interaction and network connectivity. Across all five areas, findings are predominantly context-dependent rather than uniformly positive or negative. This indicates that micromobility does not automatically improve or worsen urban transport systems; instead, its effects depend on how cities manage infrastructure, governance, and modal integration. Collectively, the evidence positions micromobility as a system-shaping intervention rather than a marginal transport addition. By clarifying the transformative role of micromobility, this review outlines critical directions for future research and demonstrates that, under certain conditions, micromobility offers strategic insights for building more efficient, inclusive, and low-carbon urban mobility. This review delivers a comprehensive foundation for transport planners and other stakeholders seeking reliable, research‑based recommendations for integrating micromobility into urban mobility.
