E-bikes and e-scooters in California: what’s actually legal
California is the most fully worked-out e-mobility law in the country — a three-class e-bike system, a genuine statewide e-scooter statute, and a brand-new 2026 rule requiring certified batteries. It’s also the state where local cities go furthest beyond the baseline, especially in San Diego County.
The short answer
Where each machine stands on a US road today.
E-bike (Class 1/2/3)
750W cap, pedal-assist to 20/28mph. No licence, registration or insurance for any class.
E-scooter
15mph cap, bike lanes and roads ≤25mph. Under-18s need a helmet; adults don’t.
Class 3 e-bike
Riders must be 16+ and wear a helmet — the only e-bike class with either requirement statewide.
Battery certification
New e-bikes sold/leased in CA now need a certified battery (UL 2849 or EN 15194) with compliance labelling.
The numbers that decide it
California’s three-class e-bike system and statewide e-scooter rule (CVC §§312.5, 24016, 21207.5, 22411).
E-bikes, in detail
California’s three classes (CVC §312.5) are the clearest in the country: Class 1 is pedal-assist only to 20mph; Class 2 adds a throttle, still capped at 20mph; Class 3 is pedal-assist to 28mph. All three share the federal 750W motor ceiling. None need a driver’s licence, registration, or insurance.
- Class 3 is the only class with an age and helmet rule statewide — 16+ and a helmet, for rider and passenger. Class 1 and 2 have no state minimum age, and adults 18+ don’t need a helmet on them.
- Under-18s need a helmet on any class — this is the general California bicycle helmet law, not e-bike-specific.
- New for 2026: a rear red reflector or light with built-in reflector is required at all hours, not just at night (AB 544) — a genuinely new requirement worth checking your bike meets.
- Battery certification is now law. Since 1 January 2026, e-bikes sold or leased in California must have a battery tested to a recognised standard (UL 2849 or EN 15194) with compliance labelling. Check for this mark before buying.
The San Diego County exception
San Diego County is the epicentre of local e-bike regulation in California. Chula Vista, La Mesa and San Marcos restrict sidewalk riding; six county cities had under-12 Class 2 bans in force by December 2025; and Encinitas and Oceanside now allow seizure of a bike for reckless operation, with Oceanside’s rule taking effect 28 February 2026. If you’re in or visiting this area, check the specific city’s ordinance — the state baseline is not the full picture here.
E-scooters, in detail
Unlike many states, California has a real, specific e-scooter statute (CVC §22411 and related sections), not just “treated like a bicycle.”
- 15mph statewide speed cap — lower than the e-bike Class 1/2 limit.
- Sidewalks are generally off-limits, except when entering or exiting adjacent property. Some cities add stricter bans in specific areas (parks, beach paths).
- Not allowed on roads with a speed limit over 25mph, unless a specific bike route is designated.
- No helmet law for riders 18 and over — required only for under-18s.
- DUI laws apply exactly as they do to motor vehicles.
The e-bike trap: continuous vs peak watts
The single most common e-bike buying mistake — and it applies directly to the federal 750W line.
US federal law (15 U.S.C. § 2085) measures continuous rated power — what the motor sustains, which must be 750W or less for the bike to qualify as a “low-speed electric bicycle” at all. But that’s rarely the number marketing leads with; sellers advertise peak power, a brief burst that can be double or more. A “750W” bike with a 1,500W peak rating can be perfectly legal — the continuous figure is what the statute measures.
Ask the seller for the continuous rating in writing, and look for a permanent manufacturer’s label on the frame showing the class number, top assisted speed, and motor wattage — required in most states that have adopted the three-class system, and your best evidence of compliance if ever questioned.
What it costs
Check your specific city’s municipal code — California’s local variation is the widest of any state covered here.
Before you hand over the money
- Check for the 2026 battery certification mark (UL 2849 or EN 15194) — required on new e-bikes sold or leased in California from 1 January 2026.
- Confirm continuous, not peak, wattage stays at or under 750W across all three classes.
- If you’re in San Diego County, check your specific city first — sidewalk bans, under-12 restrictions and seizure rules vary block by block, not just city by city.
- Fit the new all-hours rear reflector/light — required regardless of time of day since AB 544.
- For a Class 3, budget for the age and helmet requirement — the only class where both apply statewide.
Common questions
Do I need a licence for an e-bike in California?
No — none of the three classes require a driver’s licence, registration, or insurance.
Do I need a helmet on my e-bike?
Only if you’re under 18 (any class) or riding a Class 3 (any age). Adults 18+ on Class 1 or 2 don’t need one under state law.
Can I ride my e-scooter on the sidewalk?
Generally no — California prohibits sidewalk riding except when entering or exiting adjacent property. Some cities add further restrictions.
What’s the new 2026 battery rule?
Since 1 January 2026, e-bikes sold or leased in California must have a battery certified to a standard like UL 2849 or EN 15194, with compliance labelling — aimed at reducing battery fire risk.
Is my city stricter than the state?
Possibly, especially in San Diego County. Chula Vista, La Mesa and San Marcos restrict sidewalks; several cities ban under-12 Class 2 use; Oceanside and Encinitas allow seizure for reckless riding.
What happens if my e-bike exceeds 750W or 28mph?
It no longer meets California’s e-bike definition and is treated as a motor vehicle — meaning registration, a licence and insurance would be required, which most such bikes can’t obtain.
