Towards an Inclusive, Human-Centered Micromobility Model: Design Perspectives for Pedal-Assisted Light and Active Vehicles

Urban mobility faces complex challenges that extend beyond decarbonisation, including traffic congestion, unequal access, and infrastructural constraints. In response, micromobility has been widely promoted as a low-emission and flexible transport solution. However, conventional micromobility vehicles, such as bicycles, e-bikes, and e-scooters, often exclude significant segments of the population due to physical, functional, and perceptual barriers. Within this context, pedal-assisted quadricycles emerge as a promising alternative, combining human propulsion with electric assistance to enable sustainable operation while potentially enhancing inclusivity and active mobility. This paper investigates the potential of pedal-assisted quadricycles as inclusive, accessible, human-centered light vehicles. An interdisciplinary team adopted a Research-through-Design (RtD) approach, integrating ergonomic analysis, accessibility requirements, and technological development into coherent vehicle configurations. The study resulted in two exploratory low-TRL quadricycle concepts aimed at improving stability, safety, comfort, and overall usability. These outcomes provide a structured design basis for future national and international research initiatives and highlight the value of interdisciplinary research in advancing inclusive light vehicles design. The findings demonstrate how technological innovation, when aligned with accessibilityoriented design, can broaden usability and contribute to a more equitable transition toward sustainable urban mobility systems.
