E-Bike Age Requirements in California

Q: Is there a minimum age for Class 2 e-bikes in California?

Not statewide. Two sets of local rules exist. Marin County and all eleven of its municipalities bar riders under 16 from Class 2 e-bikes under the pilot authority of § 21214.5, effective from July 1, 2025. San Diego County cities that opted into § 21214.7 bar riders under 12 from Class 1 and Class 2. Nowhere else in California has authority to set a Class 1 or 2 minimum age — the City of Santa Cruz voted in March 2026 to adopt one and then found it lacked the power, and is now lobbying the Legislature for it.

Q: Can you buy an e-bike for a child under 16 in California?

You cannot sell them a Class 3. § 21212.5(a), added by AB 965 and effective January 1, 2026, provides that "a person shall not sell a class 3 electric bicycle to a person under 16 years of age" — an infraction with a fine up to $250. The statute draws no new/used distinction, so it reaches private and secondhand sales as well as retail. What it restricts is the sale to the minor, not a parent buying a bike that a minor will ride. Class 1 and Class 2 sales are unrestricted by age statewide.

California sets one statewide minimum age, and it applies to one class: nobody under 16 may operate a Class 3 e-bike (Veh. Code § 21213(a)). There is no statewide minimum age for Class 1 or Class 2 — a 9-year-old may lawfully ride a Class 2 on a California street unless a local rule says otherwise. Under-12 and under-16 rules exist only where the Legislature authorized a specific county to opt in: Marin County may bar under-16 riders from Class 2 (§ 21214.5), and San Diego County cities may bar under-12 riders from Class 1 and 2 (§ 21214.7). Both pilot statutes sunset January 1, 2029.

The statewide rule, and the gap it leaves

§ 21213(a) is one sentence: "A person under 16 years of age shall not operate a class 3 electric bicycle." Added by AB 1096 in 2015, effective January 1, 2016, and never amended since.

That is the entirety of California's statewide age regulation of e-bikes. The silence on Class 1 and Class 2 is not an oversight anyone has managed to fix — bills to lower the Class 1/2 assist cutoff and add age rules (AB 1557, 2026) have died, and the Legislature has instead handed narrow opt-in authority to two counties.

The gap is real and large. A 9-year-old may lawfully ride a 20 mph throttle-controlled Class 2 e-bike on a California street, helmeted, with no license, no training and no supervision requirement, in every jurisdiction that has not adopted a local rule.

The two county pilot programs

The Legislature authorized exactly two counties to set stricter age rules, and a third is pending. The structure is nearly identical in each.

	Marin — `§ 21214.5`	San Diego — `§ 21214.7`	San Mateo — `§ 21214.9`
Authorizing bill	AB 1778, Ch. 1005/2024	AB 2234, Ch. 823/2024	AB 2595 — pending
Restriction	Under 16 on Class 2, and/or helmets all ages on Class 2	Under 12 on Class 1 or 2	Under 12 on Class 1 or 2
Who may adopt	county and any local authority within it	county and any local authority within it	county and any local authority within it
Public information campaign	—	≥30 days before enactment	≥30 days before enactment
Warning-only period	first 60 days	first 60 days	first 60 days
Fine	$25, dismissible on proof of a safety course	$25 or course completion	$25 or CHP course completion
Parent liability	joint and several	joint and several	joint and several
Report to Legislature	January 1, 2028	January 1, 2028	January 1, 2030
Sunset	January 1, 2029	January 1, 2029	January 1, 2031

Both enacted pilots require the adopting agency to report traffic stops, citations, demographic data on persons stopped, searches and seizures, officer actions, course completions, and before-and- after crash statistics. That reporting obligation has itself become a point of local objection — an Imperial Beach councilmember cited the requirement to report "the age, ethnicity, gender of people who have been pulled over" as a reason to decline an age ban.

A discrepancy worth knowing: the Assembly Transportation Committee's April 20, 2026 analysis of AB 2595 states that the Marin pilot has "no specified sunset date." AB 1778's chaptered text says § 21214.5 "becomes inoperative and is repealed on January 1, 2029." Marin County's own public page also omits the sunset. The bill text is the better authority — the committee analysis appears to be in error.

Marin: what was adopted and how it is enforced

Marin County's Board of Supervisors approved the ordinance 4–0 on May 20, 2025, effective July 1, 2025: unlawful for a person under 16 to operate a Class 2 e-bike, and helmets required for all Class 2 riders and passengers regardless of age.

All eleven Marin municipalities adopted parallel ordinances:

Jurisdiction	Effective
Tiburon, Belvedere, Mill Valley, Corte Madera, Larkspur, Fairfax, San Anselmo	July 1, 2025
Sausalito	August 1, 2025
Novato	August 22, 2025
San Rafael	September 2, 2025
Ross	September 14, 2025

The enforcement design matters as much as the rule. Marin enforces it as a secondary infraction — county staff have stated publicly that "children will not be stopped based on their perceived age," and that officers address it only incident to another stop. Marin officials have told other jurisdictions considering similar rules that proactive enforcement is unrealistic given police resourcing, and that the program is education-first.

San Diego County: the under-12 cluster

§ 21214.7 let San Diego County and its cities bar under-12 riders from Class 1 and Class 2. Nine jurisdictions have adopted it:

City of San Diego — SDMC § 84.19, added July 14, 2026 by O-22123 N.S., effective August 13, 2026. A 60-day grace period made citations enforceable from October 12, 2026. Fine $25, waived on completing a free online safety course within 120 days (SDMC § 84.20).
Carlsbad — CMC § 10.56.030, $25 first violation, waived on safety training within 120 days, parents jointly liable.
Chula Vista — CVMC Ch. 10.73, the toughest schedule in the county: $50 / $100 / up to $250, plus impoundment and a possible facility ban after three infractions.
Coronado — effective January 3, 2025, warnings only for 60 days, then fines up to $25.
Poway — PMC Ch. 10.57, adopted February 2026, and broader than the statute's default: under 12 barred from e-bikes of any class.
La Mesa — approved 5–0 April 21, 2026, effective after a 30-day outreach campaign, then 60 days of warnings, then $25 waivable through training.
San Marcos, Santee, Escondido — adopted under-12 rules; code citations unverified.

Two San Diego County jurisdictions affirmatively declined an age ban, and their reasoning is instructive:

Oceanside looked at its own citation data — 139 citations since September 2024, of which only 11.5% went to riders under 12 — and rejected the under-12 ban in January 2026. Police Captain Scott Garrett: "The vast majority of our data reflects an older demographic."
Imperial Beach councilmembers stated in February 2026 that they will not impose an age-based ban, expressly distinguishing themselves from the six cities that had.

Carlsbad's own data cuts the same way. Roughly 220 crashes from 2022 to 2025, 63% rider-at-fault, with only nine crashes involving riders under 12 — while 12- to 17-year-olds were the largest at-fault group. The under-12 ban was criticized on adoption as poorly targeted for exactly this reason, and Carlsbad's Council subsequently directed staff to explore state legislation raising the minimum age to 16.

That tension is the central unresolved question in California e-bike age policy: the available local data consistently points at teenagers, and the available legal authority reaches only under-12s.

Where cities cannot go

The City of Santa Cruz is the clearest illustration of the limits. In March 2026 its Council approved an e-bike ordinance update with three components: a minimum rider age for Class 1 and Class 2, speed limits on multi-use paths, and fines for sidewalk riding. Only the third was within the city's authority. Santa Cruz is now seeking state legislation to let it set its own minimum age, "potentially as low as 10."

So any report that Santa Cruz has a minimum e-bike age is wrong. The age component is aspirational and unenforceable.

The same constraint explains why a city outside Marin or San Diego County cannot adopt an age rule however much its council wants one — and why the pending AB 2595 for San Mateo County matters. If signed, it opens a third county and, given San Mateo County's expressly stated intent to model an ordinance for its twenty cities to adopt, a likely second wave.

Related rules involving minors

Sales. § 21212.5(a), effective January 1, 2026: "A person shall not sell a class 3 electric bicycle to a person under 16 years of age." Infraction, fine up to $250 (§ 21212.5(b)). The statute draws no new/used distinction — private and secondhand sellers are covered too.

Impoundment. § 22651.08(a)(2) authorizes impoundment of a Class 3 ridden by an under-16 rider. Many local ordinances add their own seizure authority for minors specifically — Carlsbad's CMC § 10.56.040 requires a 48-hour hold, completion of approved safety training, and a parent or guardian present before release. Huntington Beach's HBMC § 10.84.150 and Newport Beach's NBMC § 12.56.080 both release a minor's device only to a responsible adult.

Diversion. A growing number of cities offer a first-offense diversion for minors instead of a fine: Newport Beach (NBMC § 12.56.080), Santa Barbara (via the CADA Youth Diversion Program), Encinitas (EMC § 14.56.080), and San Diego's 120-day online course. Sacramento County and Livermore offer non-monetary alternatives including temporary deprivation of the bicycle.

Schools. AB 1569 (Ch. 128, Stats. 2026), signed August 27, 2026, establishes a standardized e-bike safety and training program in the Education Code. Reporting indicates it directs the California Department of Education to develop a program for grades 7–12 by March 2028, though the bill was amended substantially and the final enrolled scope has not been verified here — earlier versions covered K–12 and named the CHP as developer. Several districts already require training independently: Santa Barbara Unified, and Branciforte and Mission Hill middle schools in Santa Cruz, which from spring 2026 require a three-part e-bike safety course for a campus parking permit.

Common questions

How old do you have to be to ride an e-bike in California?

For Class 1 and Class 2, there is no statewide minimum age. For Class 3, you must be at least 16 (§ 21213(a)). If someone tells you California has a general minimum age for e-bikes, they are describing either a Class 3 rule or a local ordinance — most likely one of the San Diego County under-12 bans or Marin County's under-16 Class 2 rule.

Can a 12-year-old ride an e-bike in California?

On a Class 1 or Class 2, yes under state law — with a helmet, since they are under 18. On a Class 3, no. Locally the answer may differ: a 12-year-old is at or just above the line in the San Diego County cities that adopted under-12 bans (San Diego, Carlsbad, Chula Vista, Coronado, Poway, La Mesa, San Marcos, Santee, Escondido), and below Marin County's under-16 Class 2 line.

Is there a minimum age for Class 2 e-bikes in California?

Not statewide. Two sets of local rules exist. Marin County and all eleven of its municipalities bar riders under 16 from Class 2 e-bikes under the pilot authority of § 21214.5, effective from July 1, 2025. San Diego County cities that opted into § 21214.7 bar riders under 12 from Class 1 and Class 2. Nowhere else in California has authority to set a Class 1 or 2 minimum age — the City of Santa Cruz voted in March 2026 to adopt one and then found it lacked the power, and is now lobbying the Legislature for it.

Can a minor be cited for riding a Class 3 e-bike in California?

Yes, and since January 1, 2026 the consequence is more than a fine. § 22651.08(a)(2), added by AB 875, authorizes a peace officer to impound a Class 3 e-bike ridden in violation of § 21213(a). Release requires a minimum 48-hour hold and payment of removal and storage costs, and the agency may require proof that the rider completed an e-bike safety and training program (§ 22651.08(d)).

Can you buy an e-bike for a child under 16 in California?

You cannot sell them a Class 3. § 21212.5(a), added by AB 965 and effective January 1, 2026, provides that "a person shall not sell a class 3 electric bicycle to a person under 16 years of age" — an infraction with a fine up to $250. The statute draws no new/used distinction, so it reaches private and secondhand sales as well as retail. What it restricts is the sale to the minor, not a parent buying a bike that a minor will ride. Class 1 and Class 2 sales are unrestricted by age statewide.

How young can a child be to ride as a passenger on an e-bike?

There is no minimum passenger age, but there is an equipment rule. § 21204(b) requires a passenger to be on a separate seat attached to the bicycle, and if the passenger is four years of age or younger, or weighs 40 pounds or less, that seat must have "adequate provision for retaining the passenger in place and for protecting the passenger from the moving parts." A passenger under 18 needs a helmet, and on a Class 3 so does a child in a towed trailer (§ 21213(b)). From January 1, 2027, AB 1614 extends the passenger-seat rule from highways to Class I bikeways as well.
