Narratives of Marginalized Cyclists: Understanding Obstacles to Utilitarian Cycling Among Women and Minorities in Portland, Oregon
Amy Lubitow
Everyday cycling for transportation can have positive, population-level health impacts. Significant deterrents to cycling remain, however, particularly for women and minorities. Narratives of Marginalized Cyclists, a NITC project conducted by Amy Lubitow of Portland State University, explores the experiences of women and minorities biking in Portland, Oregon. Lubitow interviewed 28 Portlanders who self-identified as a woman or as a racial/ethnic minority (or both), and based on the insights g...
