California E-Bike Laws 2026: Helmet + Class 3 Rules

The 30-second answer

California adopted the federal three-class e-bike framework in 2015 through AB 1096, codified at California Vehicle Code §312.5. The statute was significantly tightened by SB 1271, signed September 2024 — its UL 2849/UL 2271 certification requirements and frame-label rules became operative 1 January 2026 (rental provisions take effect 1 January 2028).

You do not need a driver license, registration, or insurance to ride a compliant e-bike (CVC §24016(b)). The big things to know: Class 3 riders must be 16+, all Class 3 riders must wear a helmet at any age, and Class 3 path access is governed by local ordinance — the statewide statutory default since AB 1909 (2023) is permission on paths, not the prior ban.

Quick reference

Speedometer is required on Class 3 e-bikes (CVC §312.5). All three classes cap rated motor power at 750 W.

The three-class system in California

California's e-bike framework lives in CVC §312.5, originally enacted by AB 1096 (Chiu, 2015) effective 1 January 2016. Most recently amended by SB 1271 (Min) — Stats. 2024 Ch. 791, signed 27 September 2024 — which tightened class definitions, codified the walk-mode rule, and added the UL 2849 system + UL 2271 battery certification regime. Most SB 1271 provisions became operative 1 January 2026 (rental provisions 1 January 2028).

Class 1 — pedal-assist only, 20 mph cutoff

The motor only engages when you are pedalling. There is no throttle. The motor cuts out at 20 mph. Class 1 is the most universally permitted class in California — every road, bike lane, and bike path that allows bicycles also allows Class 1 e-bikes.

On mountain-bike trails, Class 1 is usually the only allowed class. East Bay Regional Parks, for example, opens all trails to Class 1 but restricts Class 2 to paved Regional Trails and bans Class 3 entirely.

Class 2 — pedal-assist plus throttle, 20 mph cutoff

Adds a throttle so you can move without pedalling. Same 20 mph cap. Class 2 is allowed on every road and bike lane and on most bike paths, though increasingly restricted on multi-use trails because non-pedalling riders are harder for other path users to anticipate.

Several San Diego County cities have moved to ban Class 2 operation by under-12s, and Marin County can prohibit under-16s from operating Class 2 under AB 1778. See "Local variations" below.

Class 3 — pedal-assist only, 28 mph cutoff

No throttle (in California — SB 1271 closed the loophole that previously allowed Class 3 throttles up to 20 mph). Pedal-assist to 28 mph. Speedometer required.

Class 3 carries the most restrictions of any class:

• Minimum age 16 to operate (CVC §21213)
• Helmet required for all riders regardless of age (CVC §21213)
• Permitted on Class I bike paths by default since 1 January 2023 under CVC §21207.5 (as amended by AB 1909). §21207.5(b) lets local authorities prohibit e-bikes on equestrian, hiking, or recreational trails (not Class I bike paths). §21207.5(c) lets California State Parks prohibit e-bikes on bicycle paths or trails within DPR jurisdiction. Local cities/counties seeking to ban Class 3 on Class I bike paths must rely on separate police-power authority
• Allowed on roads and Class II (painted) bike lanes everywhere

Where each class can ride

On roads

All three classes are allowed on every public road in California. There is no class restriction on roadways.

Class II bike lanes (painted lanes within a roadway)

All three classes are allowed. CVC §21207.5 explicitly carves out lanes "within or adjacent to a roadway."

Class I bike paths (separated paths and multi-use trails)

CVC §21207.5 is the controlling statute. AB 1909 (2022), effective 1 January 2023, REMOVED the prior Class 3 carve-out — today the statute reads:

"Notwithstanding Sections 21207 and 23127 of this code, or any other law, a motorized bicycle shall not be operated on a bicycle path or trail, bikeway, bicycle lane established pursuant to Section 21207, equestrian trail, or hiking or recreational trail, unless it is within or adjacent to a roadway or unless the local authority or the governing body of a public agency having jurisdiction over the path or trail permits, by ordinance, that operation."

Subsection (b) lets a local authority prohibit "an electric bicycle or any class of electric bicycle" on equestrian, hiking, or recreational trails; subsection (c) gives California State Parks the same authority.

In plain English: all three classes of electric bicycle are permitted on Class I bike paths by default since 1 January 2023. Only "motorized bicycles" (CVC §406-type mopeds) are statutorily banned by §21207.5(a). Subsection (b) lets local authorities (cities, counties, local park districts) prohibit e-bikes on equestrian, hiking, or recreational trails (NOT Class I bike paths). Subsection (c) lets California State Parks prohibit e-bikes on bicycle paths or trails within DPR jurisdiction. Local cities and counties seeking to ban Class 3 on Class I bike paths must rely on separate police-power authority (e.g., a municipal micromobility ordinance) — and many have. Always check the trail-operator posting.

Sidewalks

No statewide rule. Regulated by local ordinance and varies city by city. San Francisco allows under-13s only (with carve-outs for the Embarcadero corridor). Most coastal beach cities prohibit sidewalk riding for all ages.

Mountain bike trails

Allowed-class varies by land manager. Most California land managers default to Class 1 only on singletrack. Class 2 and Class 3 are typically restricted to paved or fire-road surfaces.

State parks, national parks, and beach paths

California State Parks

Per the California State Parks e-bike policy:

• Roadways within all park units: all three classes allowed
• State Park trails and controlled-access roads: Class 1 may be allowed only by Superintendent's Order. Class 2 and Class 3 are not allowed.
• State Vehicular Recreation Areas (OHV parks): any class may be allowed by Superintendent's Order

National Park Service land in California

The federal rule (NPS Order 3376 + 36 CFR §4.30(i)) allows e-bikes only where regular bicycles are allowed AND only on routes the park superintendent has specifically opened to e-bike use.

• Yosemite: Park policy allows e-bikes (any class, ≤750 W) wherever regular bicycles are allowed — primarily paved roads and bikeways. 15 mph cap on all paved bikeways. Verify the current Yosemite Superintendent's Compendium for any park-area-specific restrictions before riding the Hetch Hetchy or backcountry road areas.
• Sequoia, Joshua Tree, Lassen, Pinnacles: Default federal rule applies — paved and maintained roads where bikes go. Check each park's compendium before you ride; specific closures change annually.

The Marvin Braude Bike Trail ("The Strand", 22 miles, Will Rogers to Torrance)

The Santa Monica section permits Class 1 and Class 2 e-bikes; motorised pedicabs are prohibited. Class 3 access along the full 22-mile trail varies by jurisdiction — Santa Monica, Manhattan Beach, Hermosa Beach, Redondo Beach, and Torrance each have their own micromobility ordinances and several restrict or ban Class 3. Check the specific city's municipal code before riding Class 3 on the Strand.

Lake Tahoe Basin

A January 2026 USFS Lake Tahoe Basin Management Unit decision opened 112 miles of trails to e-bikes, including Flume Trail, Incline Flume, Pope-Baldwin, Angora Ridge, Gunmount, Meeks Creek, Blackwood Canyon, Kingsbury Stinger, and Stateline Lookout.

Helmet, age, license, and registration

Helmet requirements

• CVC §21212: Every cyclist under 18 must wear an ASTM- or CPSC-certified helmet. Applies to bicycles AND e-bikes of any class.
• CVC §21213 (Class 3 specific): Every operator and passenger on a Class 3 e-bike — regardless of age — must wear an ASTM or CPSC helmet. California is one of the strictest states in the country on this rule.

Minimum age

• Class 1 and Class 2: no statewide minimum age. Local rules apply (see Marin and San Diego County below).
• Class 3: 16 years old minimum (CVC §21213).

Driver license, insurance, registration

None of these are required to ride a compliant e-bike in California. CVC §24016(b) explicitly exempts e-bike operators from driver license, vehicle registration, license plate, and financial responsibility (insurance) requirements.

This exemption applies only to bikes that meet the §312.5 definition. A modified bike that exceeds 28 mph pedal-assist or 750 W rated power falls out of §312.5 and is reclassified as a motorized bicycle (moped) under CVC §406 — which DOES require registration and an M1/M2 license.

California e-bike helmet rule for under 18 (2026)

Riders under 18 must wear a helmet on any e-bike, any class — Class 1, Class 2, or Class 3 — under CVC §21212. The helmet must meet ASTM F1447 or CPSC 16 C.F.R. part 1203 standards and be properly fitted and fastened. §21212(a) is written for "a bicycle," and electric bicycles are bicycles under §312.5 — meaning the under-18 helmet rule applies to e-bikes by operation of the §312.5 incorporation. §21212(f) explicitly contemplates a "specialized electric bicycle safety course" as part of the youth-violation correction path, confirming the legislature treats e-bikes as covered.

Separately, CVC §21213 requires every Class 3 operator and passenger to wear a helmet — regardless of age. So:

• Under 18, Class 1 or 2: helmet required (CVC §21212).
• Under 18, Class 3: helmet required (CVC §21212 + §21213).
• 18 or over, Class 1 or 2: helmet optional statewide (some cities require — see local section).
• 18 or over, Class 3: helmet required (CVC §21213).

First offence is a "fix-it" infraction with a $25 base fine (plus county fees, typically reaching $150-$200 after surcharges). The California DMV official bicycle FAQ confirms the helmet rule.

California Vehicle Code §312.5 — electric bicycle classes explained

CVC §312.5 is the operative statute defining electric bicycles in California. It splits them into three classes — the federal model the state adopted in 2015 (AB 1096) and significantly tightened in 2024 (SB 1271, operative 1 January 2026):

(a) An "electric bicycle" is a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts.

(1) Class 1 electric bicycle: motor provides assistance only when the rider is pedaling and ceases assistance when the bicycle reaches 20 mph.

(2) Class 2 electric bicycle: motor may be used exclusively to propel the bicycle, and ceases assistance when the bicycle reaches 20 mph.

(3) Class 3 electric bicycle: motor provides assistance only when the rider is pedaling and ceases assistance when the bicycle reaches 28 mph. Equipped with a speedometer.

The classifications are operationally enforced by §24016 (label + speedometer), §21213 (Class 3 age + helmet), and §21207.5 (path access). The DMV does not register or issue plates for any e-bike that meets the §312.5 definition — see CVC §24016(b).

Local + jurisdictional variations

California's e-bike landscape is heavily shaped by local ordinances. The state baseline above is just the starting point.

Marin County (AB 1778)

AB 1778 (Connolly) is the most-cited local pilot in California. Signed 30 September 2024; the statute is operative on the default 1 January 2025 timeline and sunsets 1 January 2029. Compliance reports are due to the Legislature by 1 January 2028. The statute authorises unincorporated Marin County to adopt local ordinances that:

• Prohibit operators under 16 from riding Class 2 e-bikes
• Require helmets for all Class 2 riders, regardless of age
• Enforce with a 60-day warning period, then $25 fines (waivable with a safety course)

These are local-ordinance options, not statewide rules — the AB 1778 statute itself does not impose the under-16 ban or all-age helmet; it gives Marin County the authority to adopt them locally.

San Diego County (Carlsbad, Encinitas, Oceanside, and more)

Under a state law signed by Governor Newsom in October 2024, San Diego County cities have moved more aggressively than any other region in California:

• Carlsbad: After a multi-year campaign on local e-bike injuries, the City Council advanced an e-bike ordinance in December 2025, adopted it 24 February 2026, and the rules took effect 26 March 2026 following a 60-day warning period. The ordinance prohibits under-12s from operating Class 2 e-bikes, restricts sidewalk riding, and gives police seizure authority for minors.
• Encinitas + Oceanside: Early-2026 ordinances allow seizure for reckless operation. Oceanside's rules took effect 28 February 2026.
• Six San Diego County cities had under-12 Class 2 bans in force by December 2025.

San Francisco

• Sidewalk riding allowed only for under-13s, with carve-outs for the Embarcadero, Marina Boulevard, and Crissy Field waterfront where adult sidewalk riding is legal
• Golden Gate Bridge sidewalks: 15 mph cap
• Golden Gate Park: no formal class restriction; Class 1 and Class 2 encouraged

East Bay Regional Park District

The September 2023 board vote at East Bay Regional Parks set rules that significantly differ from the state baseline:

• Class 1: allowed on every trail where bicycles are allowed
• Class 2: allowed on paved Regional Trails only
• Class 3: prohibited everywhere in the EBRPD system
• 15 mph maximum speed; 5 mph when passing

Los Angeles and the Beach Cities

Class 3 access on the Marvin Braude Bike Trail (The Strand) varies by jurisdiction along its 22-mile length — Santa Monica, Manhattan Beach, Hermosa Beach, Redondo Beach, and Torrance each set their own micromobility rules and several restrict or ban Class 3. Speed enforcement also varies. Check the specific city's municipal code before riding Class 3 on this corridor.

Recent legislation (2024-2025)

Pending bills (as of May 2026)

The 2025-26 California legislative session has several active bills that could change e-bike rules. Status as of this page's last verification:

For current status, check the California Legislative Information site for the specific bill, or the CalBike legislative tracker.

Penalties for violations

Most e-bike violations are infractions, not criminal offenses. Real-world consequences:

• Helmet violation (under 18 on any class, or any age on Class 3): $25 base fine under CVC §21212 / §21213. With mandatory court fees and surcharges, the all-in cost runs around $190.
• Under-16 operating a Class 3 e-bike: infraction under §21213. Some California cities (Carlsbad and other San Diego County ordinances) authorise police seizure of the bike from the minor with conditional release.
• Carlsbad and similar local ordinances: police seizure authority for minors operating in violation, with probable cause of an immediate safety risk
• Operating an out-of-compliance "e-bike" (modified above 28 mph or 750 W) without a moped plate and M1/M2 license: treated as unlicensed motor-vehicle operation under CVC §406 — much steeper penalties

Enforcement comes from municipal police (cities), county sheriffs (unincorporated areas), CHP (state highways), state park rangers (state park trails), and federal LEOs (USFS and NPS land). The California Attorney General issued a 2024 consumer alert signaling that class-compliance enforcement and false-labeling claims are on the AG's radar.

Special situations

Sur-Ron, Talaria, and other "e-moto" bikes

These are NOT e-bikes under California law. Per OHV Information Bulletin 25-1 / SB 586, Sur-Ron, Talaria, and similar off-highway electric motorcycles are classified as off-highway motor vehicles. They require a California Green Sticker and can only be ridden in OHV-designated areas or on private property. They are not street-legal and cannot be converted to street-legal.

Modifying a Class 2 to go faster

If you de-restrict a Class 2 e-bike to exceed 20 mph throttle or 28 mph pedal-assist, the bike falls out of CVC §312.5 and is reclassified as a motorized bicycle (moped) under CVC §406. That requires:

• DMV registration and a moped plate
• An M1 or M2 motorcycle license to operate
• Lights, mirrors, and a VIN

Modification also typically voids the manufacturer warranty and any related liability coverage.

Can a 14-year-old ride a Class 2 e-bike in California?

Statewide: yes. California has no statewide minimum age for Class 1 or Class 2.

Locally: NOT in Carlsbad or the other San Diego County cities with under-12 Class 2 bans. NOT in unincorporated Marin County for under-16s under AB 1778.

What about other states?

California's three-class framework is shared by the majority of US states. The biggest variations across the three-class states are whether Class 3 is permitted on bike paths and the minimum operating age for Class 3. The PeopleForBikes State Law Tracker is the authoritative source for the current per-state count.

For the federal-framework explanation, read the foundational guide: Class 1, 2, 3 e-bikes explained.

Bottom line

California is a three-class state with stricter-than-average Class 3 rules. For most California riders, a switchable Class 1/2/3 e-bike gives the most flexibility — ride Class 3 on roads where the speed matters, drop to Class 1 for bike paths and state-park trails.

Stay compliant: 16+ to operate Class 3, always helmet on Class 3, keep your bike inside the §312.5 envelope (750 W rated, 28 mph pedal-assist cap), and check local ordinances before riding on coastal bike paths or in San Diego or Marin Counties.
