SF E-Bike Accidents Spark Law Debate

California lawmakers are weighing new e-bike rules as Bay Area crashes involving children and teens push safety, speed and liability into Sacramento. (patch.com) One proposal, Senate Bill 1167 by Sen. Catherine Blakespear, advanced out of the Senate Transportation Committee in April 2026 and would bar higher-powered vehicles from being marketed or sold as e-bikes. Another, Assembly Bill 1942, would require registration and license plates for some e-bikes under the “E-Bike Accountability Act.” (peopleforbikes.org, cal.streetsblog.org) Assemblymember Diane Papan of San Mateo also said in January that she was pursuing legislation to tighten power limits, with anything above 750 watts treated as a vehicle requiring a license. ABC7 reported Petaluma police were pressing for changes after several youth crashes in the North Bay. (abc7news.com) California already uses a three-class system. State law says Class 1 and Class 2 e-bikes top out at 20 miles per hour, while Class 3 e-bikes assist up to 28 miles per hour and require riders to be at least 16. (leginfo.legislature.ca.gov, leginfo.legislature.ca.gov) Helmet rules also tighten with speed. California requires helmets for all riders under 18 on any e-bike, and for every rider on a Class 3 e-bike, regardless of age. (leginfo.legislature.ca.gov) The pressure for new rules follows a string of Bay Area cases. In San Jose, police said a boy riding an e-bike died after a solo crash on March 19, 2026, near Remington Way and Allenwood Drive. (cbsnews.com) In Burlingame, a crash on Aug. 8, 2025, began when an 11-year-old on an e-bike collided with an SUV leaving a parking lot, and the SUV then jumped a curb and killed 4-year-old Ayden Fang, according to ABC7 and Patch. Prosecutors said on Jan. 15, 2026, they would not file criminal charges against the 19-year-old driver, and Ayden Fang’s parents later sued the city, the driver and the e-bike rider’s parents. (abc7news.com, patch.com, abc7news.com) Marin County moved ahead with its own restrictions in March 2025 after county officials said riders ages 10 to 15 had an e-bike crash rate five times higher than any other age group. County public health officials also said 911 calls tied to all bike crashes among school-aged youth rose 110% from 2019 to 2022. (cbsnews.com, marincounty.gov) The market has grown fast enough that local officials are struggling to separate legal e-bikes from heavier, faster machines sold with pedals. The U.S. Department of Energy said 1.1 million e-bikes were sold in the United States in 2022, nearly four times the 2019 total. (energy.gov) Injury data has climbed just as quickly. A 2024 JAMA Network Open study cited by University of California, San Francisco found U.S. e-bike injuries rose from 751 in 2017 to 23,493 in 2022. (jamanetwork.com, ucsf.edu) Bike advocates back some of the Sacramento push and oppose other parts of it. CalBike and Streets For All support bills aimed at illegal e-motos sold as e-bikes, while Streetsblog reported bike-safety advocates criticized AB 1942’s license-plate plan as a burden on legal riders rather than a fix for unsafe machines. (calbike.org, cal.streetsblog.org) The next fight is over where California draws the line between a bicycle with a motor and a motor vehicle with pedals. That answer will shape what kids can ride, what parents can buy, and who gets blamed when a crash turns deadly. ([peopleforbikes.org](https://www.peopleforbikes.org/news/cal
