- π **Environmental Benefits**: Cycling is recognized as an economical, healthy, and eco-friendly transport option that aids in achieving carbon neutrality.
- π **Research Focus**: A substantial body of research has explored various aspects of bike share usage, with a particular emphasis on the built environment compared to other factors like socio-demographics and psychological influences.
- π **Research Gaps**: There is a lack of consensus on how the built environment affects bike share usage across different urban contexts, and insufficient studies on the differences between docked and dockless systems.
- π **Future Directions**: The paper aims to summarize existing findings, identify gaps in research, and suggest future research directions to enhance bike share system management and urban planning.
