Ashley Ribeiro
2026

This research brief explores the landscape of electric bikes (e-bikes) and ridership in California, including the evolution of e-bike policies, rider use and demographics, and features of emerging e-bike safety programs. It discusses crash data reporting and explores limitations for capturing e-bike crash data, providing insights into potential solutions with a case study on Marin County. Findings indicate that decision-making when riding e-bikes may be influenced by environmental factors, while safety courses offer avenues to engage both students and guardians in the learning experience...
