Kids on throttles. One county has a rule that is starting to work.
A research briefing on e-bike safety for Newport Beach and Orange County, built around California's two youth e-bike pilots, Marin and San Diego: what the data says, what has been tried, how pediatricians can carry the message, and what it would take to bring a rule here.
Children arriving as e-bike trauma patients at Orange County's pediatric trauma center (Rady Children's Health OC, formerly CHOC). A trauma activation means a full team assembled for a severe, possibly life-threatening injury.7,10
The position
Educate before the purchase. Engage Sacramento. Enforce one clear line.
Newport Beach should lead Orange County to the rule Marin has and the well-check San Diego has, and do it through all three Es at once. Two parallel tracks start now: a county health directive that puts e-bikes into every child and teen well-check, and a resident campaign that floods state representatives until Orange County gets its own e-bike safety pilot.
Education
Ask at the well-check
Have Orange County's health officer do what San Diego County's did in May 2026: direct every pediatrician to ask about e-bikes at child and teen well visits, hand parents the AAP age guidance (no e-bike under 12, no throttle under 16), and send them home with a helmet and a referral to the riding course. Reaches the buyer before the bike is bought.
County health department. Needs no state permission. Starts first.Engagement
Flood Sacramento
Cities cannot set e-bike age limits; only the Legislature can, and it has done so for Marin and San Diego. So residents write, call and show up until Orange County gets the same. Newport Beach leads with a council resolution, a standing coalition of doctors, schools, police, bike shops and parents, and a public scoreboard of crashes and stops.
Residents, council, coalition. Irvine and Laguna Beach are already on record for a pilot.Enforcement
One clear line, a class not a fine
Under 16, no throttle, helmet on every Class 2 rider, modeled on Marin's pilot: $25 or a safety course, 60 days of warnings, parents jointly liable, numbers published quarterly with the demographic fields that answer the equity question. Meanwhile, use the e-moto impound authority the city already has.
Sacramento for the rule. City Hall for the rest, today.Everything that follows is the evidence for those three sentences.
1. The short versionEight findings and one legal catch
- 28%
Marin's rule is showing early results. After Marin barred under-16s from throttle (Class 2) e-bikes, the e-bike crash rate for ages 10 to 15 fell from 16.25 to 11.65 per 10,000 residents in one year. The county itself warns the numbers are small and one more year of data is needed.1
- 10x
Orange County is the center of the problem. CHP-reported e-bike crashes in the county went from 34 in 2020 to 347 in 2025, with three deaths. That is about a quarter of all reported e-bike crashes in California, in a county with 8% of the state's people.15,28
- 80%
The injured kids are mostly teenage boys. Of an estimated 15,121 pediatric e-bike injuries nationally from 2019 to 2023, 79.7% were male and 71.3% were ages 13 to 18. Speed-related crashes produced far more head, neck and face injuries.8
- ~90%
Much of what kids ride is not legally an e-bike. A state-commissioned study counted electric two-wheelers at a dozen Northern California middle and high schools and found almost 90% may not meet the legal definition. Some had eight times the legal power.29
- 34
Orange County has 34 cities and 34 rulebooks. The 2024 Grand Jury found most cities had no e-bike ordinance, few tracked injuries, and rules changed at every city line. Newport-Mesa's school board has said the same about Newport Beach and Costa Mesa.20,10
- Age 12
Pediatricians already recommend what both pilots made law. The American Academy of Pediatrics' August 2026 guidance says no e-bikes under 12, pedal-assist only from 12 to 15, throttles from 16. Its author is a UC Irvine pediatrician. Nearly every California child sees a clinician at 11 or 12 for the 7th-grade shot, and San Diego County's health officer has already asked doctors to screen for e-bike use at those visits.59,71,88
- 12.6
San Diego's under-12 rule sits below most of the injured. The City of San Diego joined seven county cities in August 2026 with a unanimous vote and an education-first rollout. But Rady Children's own data puts the average injured e-bike rider at 12.6 years old, and 71% of pediatric e-bike injuries nationally are ages 13 to 18. Carlsbad has asked the state to move its line to 16. For Newport Beach, Marin's line fits the injury data; San Diego shows the process.87,8,41
- 3 Es
Everyone says "education, engagement, enforcement." Police deliver almost all of it. Irvine, Rancho Santa Margarita and Manhattan Beach use the phrase, and Newport Beach police have presented to more than 7,500 people. But that education is an officer at a school assembly, after the bike is bought, aimed at the child. Only Marin and San Diego County put a health department behind it, and only Marin publishes a scoreboard.76,77,78,22
The legal catch: Newport Beach cannot simply copy Marin
E-bike age limits are set by the state Vehicle Code, and cities cannot change them on their own. Marin got its rule because the Legislature passed AB 1778, which authorizes only Marin jurisdictions to set an under-16 Class 2 limit, as a pilot that expires January 1, 2029. San Diego County got its under-12 pilot the same way through AB 2234, and San Mateo County is seeking one now. Two Orange County cities, Irvine and Laguna Beach, registered support for the San Diego bill in 2024, so the county has already been on record.2,3,81,45
So the honest campaign promise has three parts: do everything a city can do today, lead the push for an Orange County pilot bill, and put the same advice in every pediatrician's hands in the meantime. Section 13 audits who is covering which of the three Es today, and section 14 builds the plan on all three.
2. ClassificationsThree legal classes, and the fourth thing nobody named
California law recognizes three classes of e-bike. All must have working pedals and a motor of 750 watts or less. Anything faster or stronger is a moped or motorcycle, whatever the listing calls it.39
Green is the 20 mph zone where Class 1 and 2 stop assisting. Amber is Class 3 territory. Red is motorcycle speed.
| Device | How it moves | Assist stops at | Minimum age (state) | Helmet | License or plate |
|---|---|---|---|---|---|
| Class 1 | Pedal assist only | 20 mph | None | Under 18 | No |
| Class 2 | Throttle, no pedaling needed | 20 mph | None statewide. 16 in Marin. 12 in nine San Diego County cities | Under 18. All ages in Marin | No |
| Class 3 | Pedal assist only, speedometer required | 28 mph | 16. Sales to under-16s banned since Jan. 1, 2026 | All riders | No |
| E-moto (Sur-Ron, Talaria and similar) | Throttle, often pegs instead of pedals, 2,000 to 5,000+ watts | 40 to 60+ mph | Not an e-bike. Street use needs a motorcycle license, registration, insurance | Motorcycle helmet | Yes, and most cannot be made street legal |

~90%
of electric two-wheelers counted at a dozen Northern California middle and high schools may not be legal e-bikes
Mineta Transportation Institute, report to the Legislature, December 202529
Why the throttle is the policy line
Even trained officers struggle to tell a legal Class 2 from an illegal e-moto at a glance, because both have throttles. That is the quiet strength of Marin's rule. A 13-year-old on any throttle device can be stopped: either it is a Class 2, which breaks the ordinance, or an e-moto, which already breaks state law.
The Mineta authors also found that many families buy illegal devices without knowing it, because marketing shows them on city streets and the power figures sit in fine print.29
3. Injuries and deathsThe same curve at every scale
National, state, county, city. Every dataset bends upward the same way, and none has flattened.
Estimated annual ER visits. 2017 to 2022 from a JAMA Surgery analysis of federal NEISS data; 2023 and 2024 from CPSC's own estimates, which use a slightly different method.
Sources 11, 12. CPSC is aware of 310 e-bike deaths from 2017 through 2024; collisions with motor vehicles and loss of control are the top causes. Deaths across all micromobility devices rose from 5 in 2017 to 135 in 2024.11,12
48 → 1,366
California: CHP-reported e-bike crashes, 2020 to 2025
A separate UC San Diego study of CHP records found injury collisions rising from 2 in 2018 to more than 1,500 in 2024, with children 14 and under overrepresented and e-bike riders more often at fault, usually for unsafe speed or improper turns.15,14
Orange County hospitals and cities
- 1 → 201
Rady Children's OC e-bike trauma patients, 2021 to 2025
- 11 → 70
Mission Hospital e-bike trauma patients, January to August 2020 against the same months of 2021. Child patients went from 1 to 22
- 72 → 147
Huntington Beach e-bike crashes, 2022 to 2024, with more than 160 projected for 2025
- 69%
Share of Irvine bike collisions among 13 to 16 year olds that involve an e-bike. That age band is in about half of all the city's bike collisions
Sources 7, 19, 17, 27. At Mission Hospital, about 45% of e-bike patients had no helmet. Doctors at Rady Children's report now treating about two e-bike crash victims a day, and surgeons there describe kneecap and multi-system injuries they used to see only after car crashes.19,16
Newport Beach
Newport Beach publishes no e-bike crash series, which is itself a finding. On the record:
In September 2025 a juvenile riding an e-motorcycle died after a solo crash near Superior Avenue and Nice Lane.23 The city says it and the police department "regularly receive complaints" about children without helmets, unsafe riding, Vehicle Code violations and near misses with pedestrians.25
The state Office of Traffic Safety ranked Newport Beach 9th worst of 104 similar-sized cities for bicyclists killed or injured in 2022, and 10th worst for bicyclists under 15.26

4. DemographicsTwo different groups are getting hurt
The adults who die on e-bikes and the children who fill trauma bays are different populations with different risks. A good policy says so.
Ownership is closer to even. Injury and death are not.
Sources 37, 58, 8, 54.
Law-firm analysis of CPSC data. Small numbers, read as a pattern.
Source 53.
Adults: older, often hit by cars
Injured adult e-bike riders have a median age of 39, against 30 for regular cyclists, and deaths cluster from 25 upward. About half of adult trauma cases involve traffic, and motor vehicles account for most deaths.13,54,11
Kids: teenage boys, speed, no helmet
Children went from essentially none of the nation's e-bike injuries in 2017 to 13% by 2022.12 An earlier national study found the 10 to 13 age group was the most commonly injured (44%) and that 11.5% of pediatric e-bike injuries needed hospital admission, against 4.8% for pedal bikes.9
In Marin, riders aged 10 to 15 crash at about five times the rate of every other age group on e-bikes, but only about one and a half times on regular bikes. The gap is the motor.5,32
Helmets are going the wrong way
Only 44% of injured e-bike riders nationally wore a helmet, and the odds of helmet use fell 5.6% each year from 2017 to 2022. Riders without one had 1.9 times the odds of a head injury. Estimated e-bike head injuries rose about 49-fold over the same period.12
The lead author of the Rady Children's study put it in one line: kids are on vehicles "much more like motorcycles than bicycles," mostly with no training.7
44%
of injured e-bike riders were wearing a helmet
5. Adoption and buying behaviorEight times more e-bikes, mostly bought online
Industry estimates from customs data. Only years with a published estimate are shown. A rival analyst puts 2025 nearer 1.3 million.
Sources 31, 32, 30, 34.
- 19.4%
Adoption. The share of American bike riders who used an e-bike at least once rose from 7.8% in 2021 to 19.4% in 2023. About 7% of US adults ride one monthly. Youth cycling overall is up too: ridership among ages 10 to 17 grew 15% by 2024.35,37,36
- 55%
Where they are bought. Online channels carry an estimated 55% of the US market. PeopleForBikes found retail tracking missed roughly 450,000 direct-to-consumer units in 2024. A bike that arrives in a box comes with no conversation about class, age or fit.33,34
- $1,500
What they cost. The $1,500 to $2,499 band is the largest price segment. That is a holiday-gift price in Newport Beach. The Yorba Linda 12-year-old who fractured his skull was riding an e-moto he got for Christmas.33,10
- 40 mph
What was for sale. Until May 2026, Amazon listed "e-bikes" advertised above 40 mph. It pulled them in California after the Attorney General's consumer alert and press questions. UC San Diego also found e-bike crashes concentrate in affluent communities.38,14
6. The Marin modelOne narrow rule, adopted by everyone at once
Marin did not ban e-bikes for kids. It moved throttle bikes to the same age as the fastest class, kept pedal-assist open to all ages, and had every jurisdiction in the county adopt the same text.
16.25
e-bike crashes per 10,000 residents aged 10 to 15, year before the rule
11.65
year after the rule (July 2025 to June 2026)
Marin County Public Health, EMS 911 response data, released August 11, 2026. The rate is still nearly four times that of other age groups.1
What the rule says
- No one under 16 may operate a Class 2 (throttle) e-bike
- Helmets required for every Class 2 rider, any age
- Class 1 pedal-assist stays legal for all ages
- $25 base fine (about $197 with fees), or complete a safety course instead
- First 60 days are warnings only
How they built it
- October 2023: EMS starts coding e-bike calls separately and a public dashboard goes live
- 2024: AB 1778 (Connolly) signed, authorizing Marin only
- May 2025: "E-Bikers Club" campaign with pledge, posters, Spanish materials
- July to fall 2025: the county and all 11 cities and towns adopt matching ordinances
- Schools had already restricted Class 2 parking since 2023
What to be honest about
- One year of data, small counts. The health officer cautions against overreading it
- The pilot sunsets January 1, 2029, with a report due to the Legislature in 2028
- Cycling advocates argue road design and cars, not teens, drive most deaths
- Some advocates say the cleaner fix is abolishing Class 2 statewide
Sources 1, 2, 3, 4, 5, 50. Supervisor Mary Sackett's framing is worth borrowing: "We're not trying to get kids off bikes."1
7. The San Diego modelThe other pilot: an age floor of 12, adopted city by city
California is running two experiments at once. Marin drew its line at the throttle and age 16. San Diego County drew it at age 12 for any e-bike. The AAP ladder contains both. San Diego's record, four years long and better documented, shows what the process looks like when a large city and its county go through it.
Marin
AB 1778 (Connolly), one county, sunsets 2029
- Who it reaches
- Riders under 16 on Class 2 (throttle). Class 1 stays open to all ages
- Theory
- The throttle is the risk. Move it to the same age as Class 3
- Adoption
- County and all 11 cities and towns, matching text, 2025
- Penalty
- $25 or a safety course. Parents jointly liable. 60 days of warnings
- Result so far
- Youth crash rate down 28% in year one, small numbers
- Fit to the injury data
- Covers the 13 to 15 band, where injuries concentrate
San Diego County
AB 2234 (Boerner), one county, sunsets 2029
- Who it reaches
- Riders under 12 on Class 1 or 2. Class 3 already 16+ statewide
- Theory
- Set a floor where none exists, and teach 9 to 11 year olds before they ride
- Adoption
- Opt-in, city by city. Nine of 18 cities by September 2026; Oceanside and Encinitas have not
- Penalty
- $25 or a free online course within 120 days. Parents jointly liable. 30-day campaign, then 60 days of warnings
- Result so far
- No outcome data. Report to the Legislature due January 2028
- Fit to the injury data
- Average injured e-bike rider at Rady Children's is 12.6, above the line
Sources 2, 3, 80, 81, 83, 84, 87. Both pilots require a report on stops, warnings, citations and crashes; San Diego's also records the officer's perception of each rider's race, ethnicity, gender and age.81
How the City of San Diego got there
- 2022Carlsbad passes the county's first e-bike ordinance, then declares a local emergency after two cyclist deaths in August
- Sept 2024AB 2234 signed, co-sponsored by Carlsbad. Registered support: AAP California, Coronado, Irvine, Laguna Beach, League of California Cities. Opposed: Streets for All, Ebikeaccess.org
- Jan 2025Coronado opts in first. Chula Vista, Poway, San Marcos, Santee, Carlsbad and La Mesa follow through 2025
- Mar 2026San Diego's Public Safety Committee votes unanimously to draft an ordinance. Girl Scouts testify for it; the County Bicycle Coalition against
- May 28The county public health officer issues a Public Health Alert and asks every clinician to screen for e-bike use at injury and well-child visits, using two billing codes so injuries stop being misfiled as bicycle crashes
- June 23Council approves ordinance O-2026-142 unanimously, on the consent calendar. Second reading July 7
- Aug 13In effect. Warnings only until October 12. School district police monitor routes to school from the first day of classes
- Aug 26Escondido joins, 4 to 1, the mayor dissenting
- Sept 15Three days after a 14-year-old on an e-bike is killed running a red light, the Board of Supervisors votes 4 to 1 to have county counsel pursue companies marketing e-motos as e-bikes
Sources 43, 81, 40, 87, 88, 85, 82, 83, 89, 97.
3 → 262
e-bike trauma activations at Rady Children's San Diego, 2021 to 2025. E-bikes are now the hospital's leading cause of trauma visits
More than 1,000 e-bike patients of all severities in 2025, on pace for 300 activations in 2026. Countywide in 2024: 865 emergency visits and 186 hospitalizations.90,93,94 Escondido police, citing a SANDAG study, said county e-bike crashes rose from 72 in 2019 to 643 in 2025.97
What the ordinance does
Under 12: no e-bike of any class on city roads, paths, trails, parks or boardwalks. Passengers only on a bike with a permanent second seat. Helmets under 18 restated. No electric micromobility on sidewalks in business districts; no Class 3 or scooter on any sidewalk. A $25 fine, cleared by completing the city's free online course within 120 days.83,93
Councilmember Raul Campillo, who carried it: "This is not scraped knees and elbows. These are broken femurs, broken collarbones and traumatic brain injuries." His aim was the age just below the line: "If we can focus on the 9-, 10- and 11-year-olds now, we know they are going to grow up riding e-bikes."92
What the record shows: support, opposition, and the equity question
Who backed it
- Rady Children's trauma director Dr. Romeo Ignacio: a minimum age of 12 is "a simple, practical safeguard" that still supports active transportation for older youth
- State Senator Catherine Blakespear and Assemblymember Tasha Boerner, who wrote the bill as "a mom with two children who ride them"
- The school district's police chief, the county's ambulance provider, Safe Routes to School advocates on the school board
- County Supervisor Terra Lawson-Remer, who rides an e-bike herself and calls them "an equalizer" for older residents
Who opposed it
- San Diego County Bicycle Coalition advocacy manager Ian Hembree said e-motorcycles, already illegal for riders under 16, are the main danger, and that the city is instead targeting young people who commute by e-bike. "E-bikes provide important independent mobility."98 Later he said cities are "pursuing the lowest-effort, cheapest way of doing something about the problem."91
- The 2024 committee analysis: the bill "may be premature" ahead of the Mineta study; a $25 fine is about $200 with fees; only 4 of 194 cyclists killed in California in 2022 were under 16; protected bike lanes cut crashes up to 53%
- Supervisor Jim Desmond on the lawsuits: "jumping the gun" while SB 1167 is pending
What the council worried about
- Councilmember Sean Elo-Rivera said, "I will be very closely looking to see that Black and brown youth are not being disproportionately targeted for enforcement."96
- Escondido's mayor cast the only no vote, preferring education before an age ban.97
- Oceanside's police told council that "citation and education are not sufficiently deterring" repeat riders, and added impound
Sources 82, 85, 87, 91, 92, 81, 89, 95, 96, 97, 98.
Early enforcement numbers, from the first city to enforce
- 20 / 53 / 93
Carlsbad, May to July 2026. Citations, written warnings and education contacts in the first weeks of enforcement, plus 40 impounds of e-bikes and e-motos. The most common violation was reckless riding, not age. A juvenile gets an impounded bike back only after an in-person course, with a parent present.86
- Oct 12
City of San Diego. Citations begin October 12, 2026. No enforcement or crash figures are public yet.82
What San Diego means for Newport Beach
Take the process, not the number. Unanimous votes, a 30-day campaign, 60 days of warnings, a course instead of a fine, parent liability, and stop data that answers the equity question before it is asked. That is a template a council can adopt.
The line belongs at 16 and the throttle. San Diego's own critics and its own hospital data say under-12 misses most of the injured. Carlsbad, the city that wrote the San Diego bill, has asked the state for Marin's rule.
The healthcare track has a precedent 90 miles away. A county health officer has already told clinicians to ask about e-bikes at well visits. Orange County's has not.
8. The healthcare viewThe doctor already asks about seat belts. Add one more question.
A law reaches a family after the bike is in the garage. A well check reaches the parent before the purchase, in a room where advice about seat belts, helmets and firearm storage is already expected.
American Academy of Pediatrics, HealthyChildren.org, August 2026
Source 59. The under-12 line follows CPSC advice that children 9 to 12 should not operate anything faster than 10 mph.
The law says what the doctor says
Marin's ordinance is the middle step of this ladder written into code. San Diego's is the first step. That changes the argument: the proposal stops being a crackdown and becomes medical guidance with a city's backing.
The guidance was written by Dr. Phyllis Agran of UC Irvine, a past president of the AAP's Orange County chapter. It comes with two ready-made handouts: an e-bike readiness checklist and a family riding agreement modeled on the parent-teen driving contract.59
The chair of the AAP's injury council has said the e-bike talk fits inside the helmet guidance pediatricians already give.60
Does advice in the exam room change anything?
Yes for behavior, with one firm lesson: advice works far better when the family walks out holding something. Evidence on injury rates is thinner, and the campaign should not claim more.
- 48% → 86%
Hand over the helmet. Children who reported wearing a helmet most or all of the time, before and after a pediatric emergency department gave them one along with counseling.67
- 16x
A voucher is not a helmet. In a randomized trial, parents whose child was handed a free helmet in the ED had nearly 16 times the odds of reporting helmet use. Families given a voucher to collect one elsewhere did no better than the control group.66
- 2x
Counseling alone still moves helmets. In a national parent survey, children aged 5 to 14 whose clinician had counseled them were about twice as likely to always wear a bike helmet (odds ratio 1.96).64
- 1 of 6
Helmets are the behavior clinics can shift in teens. A randomized trial in pediatric practices followed children from 5th and 6th grade to 8th and 9th. Of six targets, including alcohol, tobacco, gun storage and seat belts, only helmet use improved.65
- 18 of 20
The broader record, and the gap. An AAP review found 18 of 20 primary-care counseling studies improved knowledge, behavior or injury rates. Yet only 15% of injured children had been counseled before they were hurt.62,63
Why doctors skip safety talks, and what fixes it. In a statewide survey, 72% of pediatricians agreed firearm-storage counseling was their job, yet 80% did it at fewer than half of well visits. The barriers were time, training and nothing to hand out. 74% said they would distribute safety devices if their practice had them. The lesson: give clinicians a one-minute script and a kit. Do not ask them to build it.68
Reach: one visit nearly every child makes
~97%
of California students show proof of a Tdap booster to enter 7th grade, usually given at 11 or 12
Sources 71, 72
Annual well checks miss a lot of teenagers. About 76% of 12 to 17 year olds had a preventive visit in 2018–19, falling to about 70% in 2020–21, the lowest of any child age group.69,70
The 7th-grade immunization checkpoint is different. State law keeps a child out of class without it, so nearly every family sees a clinician at 11 or 12.71 That is the age the AAP ladder changes, the year before the 13 to 18 group that makes up 71% of pediatric e-bike injuries,8 and the grade span where Newport-Mesa has just barred e-bikes from campus.10 The parent, who is the buyer, is in the room.
Sports physicals, urgent care, emergency discharge and school nurses catch those it misses.
What an "e-bike check" looks like
Ask
Two lines on the pre-visit form every family already fills out. Does your child ride, or are you thinking of buying, an e-bike or electric motorbike? Does it have a throttle?
Advise
One minute with the AAP ladder. Under 12, not yet. From 12 to 15, pedal assist only. Helmet rated for the speed, every ride.
Equip
The family leaves with the AAP checklist and riding agreement, a one-page guide to telling a Class 1 from an e-moto, and a helmet in hand where funding allows.
Refer
A "prescription" for the city and school district riding course, so the clinic visit and the school permit become one path.
Local partners already in the field
- Rady Children's Health OC (formerly CHOC): the county's only Level I pediatric trauma center, the national e-bike study team, and Safe Kids Orange County
- Dr. Phyllis Agran, UC Irvine, author of the AAP guidance
- Providence Mission Hospital: its trauma team already runs teen education with helmet giveaways in high-injury neighborhoods
- Hoag, Newport Beach's main hospital, and local pediatric and family practices
The precedents
- San Diego County, May 2026: a Public Health Alert asked clinicians to screen for e-bike use at injury and well-child visits, counsel families on the law, and refer them to training. Its stated reason was partly data: injuries were being misfiled as bicycle crashes
- Marin, November 2023: the program began in the health department, not the council, with an advisory to clinicians the same week its dashboard launched
- UC San Diego's trauma researchers closed their 2026 study by urging pediatricians to counsel families before the first ride
What the city can and cannot do
- It cannot direct what doctors say
- It can convene the partners, print and supply the kit, fund helmets, and tie its riding course to the clinic referral
- One grade cohort is small. Ask Newport-Mesa for 7th-grade enrollment to price a helmet for every student
Sources 7, 17, 59, 74, 75, 61, 88.
On cost, a gap. A 2026 review found no dedicated cost analysis of pediatric e-bike trauma. The nearest figure is a single-center study of e-scooter injuries with mean billed charges near $95,700 per encounter, and billed charges run well above actual cost. Rady Children's OC now sees about two e-bike crash victims a day. A local cost study from Rady or Hoag would be new, and persuasive.73,16
9. Policy scorecardWhat worked, what failed, and what nobody knows yet
Verdicts reflect the strength of the evidence, which is thin everywhere. Most of these policies are under three years old.
| Policy | Verdict | What happened |
|---|---|---|
| Marin: under-16 Class 2 limit, countywide | Early, promising | Youth crash rate down 28% in year one. Uniform adoption across 12 jurisdictions removed the patchwork problem. Needs a second year of data.1 |
| Carlsbad: emergency declaration, enforcement plus education | Worked locally | After a 233% rise in bike and e-bike collisions and two deaths in August 2022, the city funded enforcement, street changes and training. Police reported injury collisions falling within months. E-bike collisions peaked at 62 in 2022. Carlsbad has since adopted the under-12 rule and asked the state to let it go to 16.43,44,41 |
| San Diego County: under-12 limit (AB 2234) | Too early, well run | Nine cities by September 2026, the City of San Diego by unanimous vote. Education-first rollout, course in lieu of fine, demographic stop data. No outcome data until the 2028 report. Its weakness is the line: the average injured rider is over 12, and Carlsbad has asked for 16. Carlsbad's first weeks of enforcement: 20 citations, 53 warnings, 40 impounds, mostly for reckless riding rather than age.40,87,86 |
| Huntington Beach: police-run school permit course, civil citations, impound | Mixed | The most copied program in OC, and Garden Grove is studying it. But crashes doubled from 72 to 147 between 2022 and 2024 while it was being built, and police logged more than 1,300 nuisance calls since 2023. Education alone has not bent the curve.17,10 |
| Education after a citation | Weak alone | The Yorba Linda father and his 12-year-old attended a police safety presentation after a citation. Seven months later the boy ran a red light on a bike modified to reach 60 mph.10 |
| City-by-city rules with no coordination | Failed | The OC Grand Jury found inconsistent rules, confusion and almost no injury tracking. Newport-Mesa's school board adopted its own policy in April 2026 partly because Newport Beach and Costa Mesa were not aligned.20,10 |
| New Jersey: license, registration and insurance for every e-bike | Backfired | In force since July 19, 2026. Police and insurers said they lacked guidance. Dealers report sales down 20% to 90%, layoffs, and disabled customers returning bikes. Critics note it does little about e-motos, the devices behind many of the crashes.46,47 |
| California license plates for Class 2 and 3 (AB 1942) | Stalled | Held in Assembly Appropriations on May 14, 2026. Did not become law.39 |
| Key Biscayne, Florida: total ban after a death | Blunt tool | State law blocked an age-based rule, so the village banned e-bikes and scooters outright after a 66-year-old cyclist was killed in a collision with a 12-year-old rider. It shows what happens when a city has no targeted option.48 |
| Clinic counseling with a helmet handed over | Worked on behavior | Reported helmet use rose from 48% to 86% after an ED handed out helmets with counseling, and a randomized trial found about 16 times the odds of use. Effect on injury rates has not been measured.67,66 |
| Vouchers, or advice with nothing to take home | Weak alone | Helmet vouchers performed no better than doing nothing. Counseling alone roughly doubles consistent helmet use but did not move seat belts, gun storage, alcohol or tobacco in young teens.66,64,65 |
| OC buyback at Angel Stadium | Unproven | Nearly 1,000 devices and about $110,000 in gift cards in one day. It shows strong parent regret and demand. No evidence yet on crashes.16 |
The pattern: narrow rules aimed at a specific device and age, adopted uniformly and paired with data and education, are holding up. Broad rules that treat every e-bike like a car, or that stop at the city line, are not.
10. Complaints and public opinionResidents are louder than the polling is deep
1,300+
e-bike nuisance calls to Huntington Beach police since 2023
Source 17
No scientific poll of Newport Beach or Orange County residents on e-bike rules exists. That is a gap and an opening. What does exist:
Complaint records. Newport Beach and its police say complaints arrive regularly and name the same things each time: no helmets, unsafe riding, near misses with people on foot. The OC Grand Jury opened its investigation because resident complaints were rising countywide.25,20
A community survey from a similar suburb. A June 2026 newspaper survey of 400-plus residents near Lake Oswego, Oregon, is self-selected, but the shape is familiar.49
San Diego's public record. The city's ordinance drew unanimous council votes and organized opposition from the county bicycle coalition. Councilmember Sean Elo-Rivera said he would watch whether enforcement disproportionately targeted Black and brown youth. Section 7 has the detail.96
Shown as an illustration of suburban sentiment, not as a measure of Newport Beach opinion.

What supporters of limits say
- Trauma doctors and EMS crews asked for Marin's rule
- Parents at the OC buyback described not knowing what they had bought
- Older residents and pedestrian groups cite sidewalk and boardwalk speed
What opponents say
- Newport-Mesa parents told the board their kids have no other way to get to school
- CalBike and allies argue road design and drivers cause most cycling deaths, and that 90% of cyclists killed are 20 or older
- Equity, two ways: an e-bike is the cheapest car replacement a family can buy, and the San Diego pilot records the officer's perception of race, ethnicity, gender and age on stops
- San Diego County Bicycle Coalition: age rules target the wrong riders; e-motos and dangerous drivers are the problem
What that means for the message
- Lead with kids' safety and keeping them riding, as Marin did
- Put pediatricians and trauma surgeons in front. "Doctor recommended" lands better than "council mandated"
- Keep pedal-assist open to every age
- Pair any limit with safe routes to school
- Commission a real local survey before the ordinance, and publish it

11. Law enforcementMore tools than two years ago, used unevenly
| Agency | What they are doing | Numbers |
|---|---|---|
| Newport Beach PD | Council voted unanimously in November 2025 to rewrite Chapter 12.56: e-bike definitions, a list of unsafe behaviors (wheelies, riding against traffic, weaving through pedestrians, extra passengers), impound authority, a diversion class for violators, and a new sidewalk-cycling map. In effect since January 2026. The boardwalk has an 8 mph limit and fines up to $200.21,22 | An early targeted operation produced 60 citations or warnings, 55 of them to bike riders. No running totals are published.24 |
| Huntington Beach PD | Directed operations on the beach path, parks and school zones. Civil citations at $150, criminal infractions near $450 with fees, impound of e-motos, referrals to the school training program.18 | One day in May 2026: 105 contacts, 32 e-bike citations, 29 school referrals, 55 warnings, 1 impound.18 |
| OC District Attorney | New e-bike and e-motorcycle unit reviewing charges against riders and parents. Ran the September 2026 buyback with asset forfeiture funds.10,16 | Four parents charged with child endangerment since January 2026, including one involuntary manslaughter case after an 81-year-old veteran was killed.57,10 |
| Irvine, Fullerton, Garden Grove | Irvine added parent liability and path speed limits. Fullerton banned "unsafe" riding after a Cal State Fullerton student died. Garden Grove police told council that fines, towing and impound can top $2,000.10 | Irvine: ages 13 to 16 are in about half of all bike collisions.27 |
| State law | Officers may impound non-e-bikes that exceed 20 mph on motor power when the rider is unlicensed, and Class 3 bikes ridden by under-16s. Minimum 48-hour hold. Selling a Class 3 to anyone under 16 is an infraction up to $250. E-bikes need a rear reflector or light at all hours.39 |
The enforcement gap an age-and-device rule closes. Most OC enforcement today depends on catching a behavior: a wheelie, a red light, a sidewalk. An age-and-device rule gives officers an objective reason to stop a young rider before the crash, and sends the family to a class for $25 instead of into court.
12. Who is movingCities and lawmakers acting on e-bikes
Age-limit pilots (need a state bill)
- Marin County and all 11 cities and towns: under 16, Class 2. Through 2028
- San Diego County: Coronado (first, January 2025), Chula Vista, Poway, San Marcos, Santee, Carlsbad, La Mesa, City of San Diego (August 13, 2026), Escondido (August 26). Oceanside and Encinitas have not opted in. County supervisors voted September 15 to pursue companies marketing e-motos as e-bikes
- San Mateo County: AB 2595 (Papan) would add an under-12 pilot through 2030. Passed the Assembly, in the Senate as of May
- Carlsbad has formally asked to join the under-16 model
Orange County
- Newport Beach: code rewrite, impound, diversion (2026)
- Newport-Mesa USD: from fall 2026, only high schoolers may bring e-bikes, with required training. Vote was 6 to 1
- Huntington Beach: permit course required to ride to school
- Irvine, Fullerton, Garden Grove, Los Alamitos, La Palma: new or tightened rules
- Laguna Beach, Seal Beach: no e-bikes on sidewalks or boardwalks. San Clemente: none on the pier, beach or coastal trail
- County (unincorporated): e-bike safety ordinance led by Supervisor Foley
- OCTA: countywide E-Bike Safety Action Plan (2025)
- Healthcare: Rady Children's OC and Safe Kids OC (research, school outreach), Mission Hospital (helmet giveaways), AAP national guidance written at UC Irvine (August 2026)
Sacramento and Washington, 2026
- SB 1167 (Blakespear): bans marketing e-motos as e-bikes, clearer labels. Passed 77 to 0, on the Governor's desk
- AB 2346 (Wilson): lets cities post 10, 15 or 20 mph path limits, 10 mph on sidewalks. On the Governor's desk
- AB 1569 (Davies): statewide grade 7 to 12 e-bike training curriculum by 2028. Signed August 27
- AB 2284 (Dixon, Newport Beach): Attorney General list of devices that are not legal e-bikes
- SB 956 (Choi): proposed an Orange County license-plate pilot. Verify current status
- Federal: Rep. Huffman's bill, inspired by Marin, would have CPSC set classes, labels and suggested ages

13. The three EsEducation, engagement, enforcement: who is actually covering what
Orange County does lean on enforcement. The sharper version, and the harder one to rebut: several agencies already claim all three Es, but one messenger delivers them.
| Program | Education | Engagement | Enforcement | Run by |
|---|---|---|---|---|
| Marin County | Yes. Health advisory to clinicians, E-Bikers Club campaign in English and Spanish, Safe Routes to Schools classes | Yes. Supervisors' special committee, all 12 jurisdictions, schools, a teen pledge, a public dashboard updated monthly | Yes. Under-16 Class 2 rule, $25 or a class, 60 days of warnings | Public health, county, transportation agency, police |
| City and County of San Diego | Yes. 30-day campaign, free online course, school-district police at the gates, county health alert directing clinicians to screen at well visits | Yes. Trauma surgeons, ambulance provider, school board, Girl Scouts and senator's office at the podium. Bicycle coalition opposed, and heard | Yes. Under-12 rule, $25 or a course, parent liability, demographic stop data. County suing deceptive marketers | Council, police, school police, county public health, county counsel |
| Newport Beach | Partly. Police presentations reached 7,500+ people from 2021 to 2023 | Partly. A working group of three council members and staff. No standing body with parents, schools, doctors or shops | Yes. 2026 code rewrite, impound, diversion class, boardwalk speed limit | Police |
| Huntington Beach | Yes. Police-taught course required for a school parking permit | Partly. Statewide symposium, council ad hoc committee | Yes. Civil and criminal citations, impound, directed operations | Police |
| Irvine | Partly. Parent buying guide, course offered after a juvenile citation | Partly. Outreach through schools and neighborhood associations | Yes. Parent liability, path speed limits | Police. Uses the three-E slogan |
| Rancho Santa Margarita | Yes. Deputies lecture at middle schools, four sessions a year | Partly. Free helmet fittings with Mission Hospital | Yes. Third phase, after an education-first period | Sheriff's police services. Three named phases |
| Manhattan Beach (LA County) | Yes. "Ride Safe, Ride Ready" campaign since 2022 | Yes. Built with the school district and two high school students | Yes. | City, police, schools |
| OC District Attorney | No. | Partly. Buyback event drew about 1,000 devices | Yes. Dedicated unit, four parents charged in 2026 | Prosecutor |
| Newport-Mesa USD | Partly. Training required for high school riders | Partly. Consulted schools and parents, but not aligned with either city | Yes. Campus ban below high school | School district |
Sources 1, 5, 75, 82, 83, 88, 89, 22, 21, 17, 18, 77, 76, 78, 16, 57, 10. "Partly" reflects what each agency has published, not an audit of its work.
Four gaps the table shows
- Who
One messenger. In Orange County the educator, the convener and the enforcer are the same uniform. A policing playbook for teen e-bike safety makes the same point from inside the profession: enforcement alone does not work, and parents, retailers and schools have to carry part of it.79 No OC program uses pediatricians, the messenger parents already trust on seat belts and helmets. San Diego County's health officer does.
- When
After the purchase. School assemblies and post-citation classes reach a family once the bike is in the garage. The Yorba Linda case is the proof: the class came after the citation, and the crash came after the class.10
- Whom
The child, not the buyer. Most education targets the rider. The decision that matters most, which device to buy and at what age, is made by a parent, often online.
- Proof
No scoreboard. Only Marin publishes outcomes; San Diego's are due in 2028. Huntington Beach, the most complete police-led program in the county, saw crashes double while it was being built.17 Without shared data nobody can say which E is working.
A caution on the phrase. In traffic safety the classic three Es are education, engineering and enforcement. The police version swaps engineering for engagement. Cycling advocates will notice; their core argument, made again in San Diego, is that street design causes most deaths. Keep the three Es as the frame, but fold safe routes to school into engagement so the answer is ready.50
14. A plan built on all threeThree Es, three messengers, one scoreboard
What is new is not the slogan. It is who delivers each E, when, and whether anyone keeps score. Tags show where each step happens. All of it should go through the City Attorney before it becomes a campaign commitment.
Education
The gap: taught by police, to kids, after the purchase. The fix: taught by doctors and schools, to parents, before it.
- Doctor's office
Put the e-bike check into the 11 to 12 visit
A shared one-minute script and kit built on the AAP age ladder, checklist and family agreement, timed for the spring and summer rush of 7th-grade Tdap visits. Ask the Orange County health officer to issue the same clinician alert San Diego's did in May 2026, including the billing codes that make e-bike injuries countable. Needs no state permission, so it can start first.
- Doctor's office
Hand over the helmet, not a voucher
A helmet in hand changes behavior and a coupon does not. Fund speed-rated helmets for clinics, the ED and the 7th-grade cohort through the city, hospital community-benefit budgets and Safe Kids OC.
- City Hall
Reach parents before they buy
An "E-Bikers Club"-style campaign each November and August, with pediatricians and trauma surgeons as the voice. Ask local shops to post class and minimum age at the point of sale, which SB 1167 and AB 2346 would soon require anyway.
- City Hall
One riding course, recognized everywhere
A single hands-on course accepted by the city, Costa Mesa and Newport-Mesa for a school permit, and reachable by a clinician's referral as well as a citation.
Engagement
The gap: a council working group and police outreach. The fix: a standing table where the people who buy, sell, ride, treat and teach all sit.
- City Hall
Stand up an e-bike safety coalition
Modeled on Marin's special committee: Rady Children's OC, Hoag, the AAP's Orange County chapter, Newport-Mesa, Costa Mesa, police and fire, bike shops, parents and teen riders. Manhattan Beach built its campaign with two high school students at the table.
- City Hall
Count first, and publish it
Have Fire and Police code e-bike, e-moto and pedal-bike calls separately, ask Hoag and Rady for ED counts, and post a monthly dashboard by age. The Grand Jury asked every city for this in 2024. Marin's dashboard is what won its legislation, and it is the scoreboard every other E gets judged by.
- City Hall
Ask residents, properly
Commission a real survey of Newport Beach residents and parents. None exists. Publish it before any ordinance.
- City Hall
Keep kids riding
Pair every restriction with safe routes to school. It answers the engineering objection and matches both Marin's message and the AAP's: biking is good for kids, and the goal is more of them riding safely.
Enforcement
The gap: officers can only act on a behavior they witness. The fix: a clear age-and-device line, a class instead of a fine, and numbers the public can see.
- Sacramento
Ask for an Orange County pilot
A council resolution requesting a bill modeled on Vehicle Code §21214.5: under 16 for Class 2, helmets for all Class 2 riders, a $25 fine or a class, 60 days of warnings, a sunset date and a report. Assemblymember Diane Dixon of Newport Beach has already carried e-bike bills. Irvine and Laguna Beach registered support for the San Diego pilot in 2024, Carlsbad has asked for the Marin line, and the AAP's guidance gives it a medical basis.
- City Hall
Use the e-moto authority the city already has
State law and the 2026 code rewrite already allow impound of e-motos ridden by unlicensed minors. These are the devices behind the worst crashes.
- City Hall
Class first, fine second, and show the numbers
Keep diversion to the riding course as the default for minors, as San Diego does with a free online course and a 120-day window. Publish stops, warnings, citations and impounds quarterly on the same dashboard, with the demographic fields a state pilot requires, so the equity question San Diego's council raised is answered with data.
15. Sources and caveatsWhere every number came from
Read the data with four cautions. First, police and hospital records often lump legal e-bikes together with e-motos, so "e-bike injuries" overstates the risk of legal bikes and understates the e-moto problem. Second, injury counts are not rates: more bikes means more crashes even if each ride is no riskier. Third, Marin's result is one year of small numbers. Fourth, clinic counseling is proven to change behavior such as helmet use, but its effect on injury rates has rarely been measured. Two figures conflict between sources and are flagged in the text: OC's share of state crashes (41% vs about 25%) and the UCSD 2024 count (1,506 in the university release, 1,566 in press coverage of the paper). Rady Children's San Diego figures (3 to 262) and Rady Children's Orange County figures (1 to 201) are different hospitals in the same system.
