California Clarifies E-Bike vs E-Moto Rules Under New Newsom-Signed Laws

California Gov. Gavin Newsom signed three e-bike and e-moto bills on September 30, 2026, aimed at clarifying what can be sold as an e-bike, giving San Mateo County a youth-riding pilot option, and adding longer-horizon equipment and sidewalk rules.

This piece summarizes the three measures covered in KQED's October 1, 2026 report and the related bill text. It is not legal advice. Always check the enrolled bill text and your local ordinance before buying or riding.

Start with SB 1167, which takes effect January 1, 2027 according to KQED and Streetsblog California: devices faster than Class 1, 2, or 3 cannot be sold or advertised as e-bikes.

California already defines an electric bicycle as a bike with fully operable pedals and a motor of no more than 750 watts, with Class I, II, and III speed and assist rules. SB 1167 does not rewrite those wattage or class speed limits. Instead, it tightens how faster devices may be marketed.

Per KQED's October 1, 2026 report: devices capable of traveling faster than 20 mph with a throttle, or 28 mph with pedal assist — California's existing e-bike speed limits — cannot be sold or advertised as e-bikes. Those devices are grouped into the moped or motor-driven cycle categories in the vehicle code, depending on maximum speed, and riders need the registration and license those categories require. Manufacturers, importers, and sellers of devices faster than e-bikes must disclose that the device is considered a motor vehicle in California. Crash reporting requirements are also strengthened so agencies can better record which device type was involved.

The bill's author is Sen. Catherine Blakespear (D-Encinitas). Streetsblog California, writing on September 30, 2026, notes the bill also strengthens labeling, disclosure, battery and electrical safety, and crash-data requirements for devices outside the legal e-bike definition.

The practical takeaway for shoppers: if an e-bike listing claims throttle speeds above Class II (20 mph) or pedal assist above Class III (28 mph), treat the label skeptically and read the class and wattage disclosure. After January 1, 2027, selling or advertising those faster devices as e-bikes is off-limits under SB 1167.

The second measure is a San Mateo County youth pilot. Newsom also signed AB 2595 (Asm. Diane Papan; San Mateo Electric Bicycle Safety Pilot Program, Chapter 843), which lets local authorities in San Mateo County prohibit riders under 12 from operating Class I or Class II e-bikes — the classes capped at 20 mph of assist — through January 1, 2031.

Key points from KQED and the bill text: each city, and the county for unincorporated areas, may adopt the pilot, so it is optional rather than automatic county-wide. State law already bars riders under 16 from Class III e-bikes. Similar pilots already exist in Marin and San Diego counties. If a local ordinance is adopted, the bill text provides for warning notices for the first 60 days and then a $25 fine, and parents or guardians of an unemancipated minor can be jointly liable. Local agencies must also run a public information campaign for at least 30 days before adopting the rule.

The practical takeaway for families in San Mateo County: watch your city's agenda. The pilot only applies where a local ordinance or resolution is passed.

The third measure is AB 2346, from Assemblymembers Lori Wilson (D-Suisun City) and Marc Berman (D-Palo Alto), also covered by KQED. Class II e-bikes sold after January 1, 2029 must be equipped with a speedometer, and the bill sets a 10 mph prima facie speed limit on sidewalks per the bill text. It does not override local rules on whether you may ride on a sidewalk at all.

The bill text also requires all e-bikes manufactured, sold, or offered for sale on or after January 1, 2029 to have a front and a rear lamp, and requires sellers to disclose specified information at or before the point of sale. If you manufacture, import, or sell, read the chaptered text.

The practical takeaway: the speedometer and lamp requirements are 2029 product rules aimed at sellers. For riders, the change that matters now is a 10 mph cap wherever sidewalk riding is allowed.

As for why lawmakers moved, KQED cites rising crash concern and mislabeled faster devices. A December 2025 Mineta Transportation Institute report, via KQED, found it was highly likely that many injury crashes thought to involve e-bikes actually involve e-motorcycles and e-mopeds, and that device-type data in crash records is often incomplete. Marc Vukcevich of Streets for All told KQED that illegal devices are making e-bikes and e-bike riders look really bad.

Separately, a July UC San Diego study cited by KQED reported California e-bike injuries rising from 2 in 2018 to just over 1,500 in 2024, with moderate-to-severe injuries more likely among children 14 and younger. Those figures are the study's reported counts via KQED, not ElectricBikes.com estimates.

So what should riders and buyers do? First, know your class: Class I and II assist or throttle stops at 20 mph, and Class III pedal assist runs to 28 mph for riders 16 and older. SB 1167 targets the marketing of devices outside those lines. Second, read the label and the disclosure before you buy, especially on online listings that use the word e-bike loosely. Third, families in San Mateo County should check whether their city opts into the under-12 Class I and II pilot. Fourth, where sidewalk riding is allowed, keep to 10 mph or less under AB 2346 — and remember that many cities ban sidewalk riding outright, so check the local rules.

One last point, because it matters: this is not legal advice. For enforcement, registration, or licensing questions, rely on official California Vehicle Code and DMV guidance and on the enrolled bill texts, which are linked below.
