Active Mobility (AM) currently presents an opportunity to change the paradigm of the competitive and dispersed city created by motorized mobility, revaluing the role of walking and cycling in generating more sustainable urban ecosystems. This article addresses the challenges and opportunities for AM to contribute to the regeneration of urban systems and the capacity for anticipation. This article analyzes AM using the Ecosystemic Urbanism (EU) as an analysis framework within its four axes: social cohesion, complexity, efficiency, and compactness and functionality. Through this analysis, the points of incidence of AM were identified within each of these axes. The study highlights the potential of AM to act as a transformative driver in urban development, integrating an ecological framework where urban systems are interconnected and mutually reinforced. This perspective reveals walking and cycling as a catalyst for reshaping urban interactions. In light of this, future cities must adopt a human urban scale through compactness that fosters complexity and diverse and engaging urban interactions. In addition, the enjoyability achieved through AM brings significant ecosystem benefits by promoting awareness of others, nature, and the interconnectedness between the individual and the city. This represents a new paradigm shift in which the automobile does not play the central role, allowing more sustainable ways of living together.
