In Bike Lanes Are White Lanes scholar Melody L. Hoffmann argues that the bicycle has varied cultural meaning as a "rolling signifier." That is, the bicycle's meaning changes in different spaces, with different people, and in different cultures. The rolling signification of the bicycle contributes to building community, influences gentrifying urban planning, and upholds systemic race and class barriers.
In this study of three prominent U.S. cities--Milwaukee, Portland, and Minneapolis--Hoffmann examines how the burgeoning popularity of urban bicycling is trailed by systemic issues of racism, classism, and displacement. From a pro-cycling perspective, Bike Lanes Are White Lanes highlights many problematic aspects of urban bicycling culture and its advocacy as well as positive examples of people trying earnestly to bring their community together through bicycling.
