Marin County Bans Throttle E-Bikes for Kids, Taking a Bold Step Toward Safety
In an unprecedented move, Marin County, California, has made headlines by banning children under 16 from riding throttle e-bikes. This decision, passed unanimously by the County Board of Supervisors on March 25, 2025, is set to go into effect on July 1, 2025, after a second vote in May. With this law, Marin becomes the first county in California to implement age restrictions on throttle e-bikes, commonly known as Class 2 e-bikes.
The county’s action comes after a troubling rise in e-bike-related accidents. Between 2019 and 2022, Marin saw a 110% spike in 911 calls related to youth bicycle accidents. In response, Marin County Emergency Medical Services took a closer look at the problem, tracking incidents involving e-bikes separately from traditional bicycles. By late 2023, they had created a dashboard to monitor trends, helping local authorities better understand the growing issue.
The tipping point arrived in December 2024, when a Fairfax mother filed a lawsuit against a California-based e-bike manufacturer. She alleged that the company was selling bikes that exceeded legal speed limits, violating California law. It wasn’t long before more people began questioning the safety of these bikes, particularly among young riders.
Throttle e-bikes, which allow riders to accelerate without pedaling through a handlebar-mounted control, have become a popular choice for kids. But these bikes come with a unique set of risks. Talia Smith, Marin County’s director of legislative and intergovernmental affairs, emphasized that throttle e-bikes are first and foremost a public health concern. A recent public comment by Bridget Clark, a former Safe Routes to School leader, echoed these concerns. Clark shared a disturbing encounter on the bike path between Kentfield’s College of Marin and MarinHealth Medical Center, where two e-bike riders terrorized pedestrians by speeding between them while performing wheelies.
The new law will not only ban children under 16 from using throttle e-bikes, but it will also require all riders of Class 2 e-bikes to wear helmets while riding in unincorporated areas of Marin. This move is part of the county’s ongoing efforts to improve safety, but it’s only the beginning. Brian Colbert, District 2 Supervisor, acknowledged that this is just one step in a long process of addressing the broader issue of e-bike safety.
In addition to safety concerns, e-bikes have been at the center of other troubling incidents in Marin. In October 2024, a 15-year-old held up two children at gunpoint on a Greenbrae bike path, demanding their e-bike keys. Incidents like these have raised alarm bells in the community and spurred officials to take action.
Supporters of the ban, such as Bob Mittelstaedt, co-founder of E-Bike Access, believe the ordinance will help parents make more informed decisions when buying e-bikes for their kids. He pointed out that any bike without a Class 2 label but equipped with a throttle should be treated like a motorcycle, not a bicycle.
While the law is a step forward, Colbert reminded the public that addressing e-bike safety is a continual process. With more e-bikes hitting the roads every year, Marin County’s decision may inspire other regions to adopt similar measures. It’s clear that while electric bikes are here to stay, finding a balance between innovation and safety is more important than ever.
