Bike equity refers to the notion that traditionally marginalized populations face disproportionate barriers to being able to bicycle safely in the communities in which they live. Notably, low-income US residents comprise the majority of bike commuters, and yet have less access to adequate bicycling infrastructure than their middle- and high-income peers. This has resulted in disparate health, employment, and education outcomes and created an additional impediment to achieving neighborhood wellness. Through a literature review and participant observation this article argues that bike equity should become a central tenet of urban sustainability, and discusses the limited empirical evidence of the best practices for promoting bicycling within marginalized communities. This review also suggests that bike equity is an area for future community psychology practice and research.
