%X This research aims to understand the relationship between car mobility and cycling in the Netherlands. Despite the high modal split of cycling, car mobility remains prevalent in the Netherlands, even at distances that are suitable for cycling. Hence, this research investigates if and how cycling can contribute to reducing car mobility. Using a transition theory multi-level perspective, these dimensions have been examined. The data is collected via statistical data, policy and document review, and interviews. The results indicate that an increase in cycling's modal split can contribute to a car reduction due to several conditions. First are external pressures from the landscape, such as climate change and the COVID-19 pandemic. Secondly, a strong political view and bottom-up initiatives are needed within the mobility regime. Third, niches like e-bikes and the 15 min. city-concept are effective. Next, promotional instruments are essential to ensure long-term results. First, bicycle incentives, such as improving physical instruments and policies, are needed to encourage cycling. Simultaneously, car restriction policies are required to discourage car use. Due to the combination of regulations and stimulations, governments, planners, private, and institutional organizations can increase cycling's modal share. Moreover, two approaches are discussed to manage the transition based on the spatial context. For urban areas, system improvement is needed, while rural areas need system innovation. Finally, further research should investigate cyclists' perceptions, the role of public transport, and the encouragement of long-distance cycling. %L theses_frw3931 %D 2022 %A L.
