California lawmakers and safety watchdogs are zeroing in on a fast-growing problem: high-powered two-wheelers being sold as e-bikes that may actually be closer to mopeds or motorcycles under state law. After a series of serious crashes and a lot of confusion at the bike rack, they are rolling out a one-two-three punch of a new Senate bill, a statewide consumer alert and fresh research showing many of the devices parked outside schools appear to blow past California’s legal limits. Supporters say the effort is about protecting kids and cleaning up a chaotic marketplace, while critics argue new labels alone will not fix weak bike infrastructure or spotty enforcement.
In a consumer alert issued April 14, Attorney General Rob Bonta warned that two-wheeled vehicles that provide pedal assistance beyond 28 miles per hour, throttle assistance beyond 20 mph, have motors over 750 watts or lack operable pedals are not e-bikes and may legally be treated as mopeds or motorcycles, according to the California Department of Justice. The alert also notes that modifying an e-bike so it exceeds those limits can effectively turn it into a different vehicle class that requires a driver license, registration and insurance. Bonta urged manufacturers, retailers and parents to scrutinize labels and follow the law to avoid both safety problems and legal trouble.
What The Data Shows
A December 2025 study by the Mineta Transportation Institute, commissioned by the state Legislature, took a hard look at what teens are actually riding to school. Researchers found that nearly 88% of electric devices parked at bike racks outside high schools in Marin and San Mateo counties were “e-motos,” meaning higher-powered machines that do not meet California’s legal definition of an e-bike, according to Mineta Transportation Institute. The report warns that the sheer number of these over-powered rides makes it harder to interpret crash data and trends, and it recommends clearer product standards, better reporting and targeted policy changes. The authors call for a mix of regulation and education so low-speed e-bikes stay accessible while the riskiest machines are kept off streets and school routes.
How SB 1167 Would Change The Market
To tackle the gray area in the marketplace, Sen. Catherine Blakespear introduced SB 1167 in February. The bill would tighten the legal definition of an e-bike and prohibit sellers from advertising, selling or labeling motor-driven cycles and mopeds as e-bikes, according to the California Legislature. Mislabeling would be treated as misleading advertising under the state Business and Professions Code, and the proposal would require clearer disclosures for higher-powered devices. Advocacy groups including CalBike are co-sponsoring the bill, arguing it would preserve access to legal e-bikes while making it easier to tell them apart from faster “e-motos.”
Kendra Ramsey, executive director of the California Bicycle Coalition, told KCRA that many buyers pick up devices online or in stores believing they are purchasing legal e-bikes, only to discover later that the machines exceed state limits. Local shop owners describe the same confusion on the sales floor: David Hall of Bikes and Riders said in the KCRA report that e-bikes can make commuting easier, but some models being sold to teens are heavier and faster than young riders or their parents expect. Supporters of SB 1167 say clearer rules would help retailers stay compliant and give families better information to make safe choices.
Critics Say It Might Not Be Enough
Not everyone is convinced that tightening labels and ad language will address the biggest dangers. Some safety experts point to deeper problems, including patchy bike infrastructure, inconsistent enforcement and poor crash reporting. KPBS reported that many advocates back SB 1167’s focus on clarity but insist that money for safer streets and better resources will matter more in the long run. Meanwhile, the San Francisco Chronicle has documented serious injuries among teens riding heavy, fast electric machines. Those critics argue the state should pair any new rules with funding for safe routes to school and improved data sharing.
How To Tell If A Bike Is Legal
Under California law, every e-bike sold in the state must have a permanent label that lists the bike’s class, its top assisted speed and its motor wattage. The Department of Justice says buyers should look for that sticker and be wary of any unit that does not have operable pedals. If a device is advertised with top speeds or wattage that exceed the legal thresholds, it may actually be a motorcycle or moped that comes with requirements for a license, registration and insurance. The alert also warns that modifying a bike so it exceeds those limits can expose both sellers and owners to legal risk. Retailers who are unsure how a particular model should be classified are encouraged to consult the bill language or state guidance before selling, in order to avoid consumer protection violations.
What’s Next
SB 1167 cleared its first major hurdle on April 7, when it passed the Senate Transportation Committee, and it now continues through the Legislature for additional votes. Sponsors say the aim is to protect riders while preserving access to low-speed e-bikes, according to Sen. Blakespear's office. If the bill becomes law, regulators would gain clearer authority to stop high-power devices from being marketed as e-bikes and to impose penalties on sellers who mislabel products. Lawmakers are expected to weigh amendments and feedback from stakeholders as the measure moves ahead.
For now, the combination of a high-profile consumer alert, the Mineta study and pending legislation has shoved e-bike safety to the top of Sacramento’s agenda. Families, retailers and schools will be watching closely as lawmakers sort out where legitimate e-bikes end and e-motos begin.
