As urban populations swell and environmental concerns escalate, cycling emerges as a sustainable alternative to motorized transport in cities like Bogotá. However, the safety of cyclists remains a critical barrier to wider adoption. This paper presents a comprehensive review of technological innovations aimed at enhancing the safety of urban cyclists. Through a meticulous synthesis of current literature and case studies, we explore a range of technologies from basic safety equipment to advanced sensor systems and smart devices that integrate with urban infrastructure. Our review identifies key areas where technology has successfully mitigated risks for cyclists, including improvements in visibility through LED lighting and reflective clothing, enhanced communication via interconnected wearable devices, and real-time tracking and environmental monitoring using advanced sensor technology. We also examine the integration of these technologies into existing urban frameworks, assessing their effectiveness and potential for broader implementation. The findings highlight significant advancements in cyclist safety, yet also underscore the need for ongoing research to address persistent challenges and ensure these innovations are accessible and effective in diverse urban settings. This paper aims to inform policymakers and urban planners about the potential of these technologies to not only improve cyclist safety but also encourage cycling as a viable and safe mode of transportation, contributing to the sustainability and health of urban environments.
