American College of Surgeons reports that e-bike incidents in California surged by 18.6 times over a span of five years. In 2018, the total was 184 accidents, which escalated to 3,429 by 2023. Consequently, California enacted a law, SB-1271, in 2025 to restrict the power of these bikes and establish additional guidelines, such as limiting the motorized support of Class I e-bikes to a maximum of 20 mph. For instance, some of the best affordable electric bikes currently reach 22 mph.
However, the new legislation known as the E-bike Accountability Act seeks to introduce traceability and responsibility into the sector. It will mandate that Class II and Class III e-bikes be registered with the DMV in California. Additionally, eligible bikes are required to display a license plate, and riders must possess proof of ownership that corresponds with the bike’s serial number to assist in identifying riders in case of an incident.
