The Vehicle That Broke the Category
E-bikes, e-motorcycles, and why the distinction matters
California's three-class e-bike system was designed with pedal-assist bicycles in mind. It wasn't designed for the electric motorcycle — a vehicle that looks like an e-bike, costs like an e-bike, and gets sold alongside e-bikes, but is legally a motor vehicle requiring registration, a license, and insurance. In Petaluma, that distinction has become the fault line of the entire debate.
Active Transportation Plan adopted — e-bikes surface as an afterthought
At the September 15, 2025 City Council meeting, Petaluma unanimously adopted its Active Transportation Plan after extensive public comment. E-bikes weren't the main event — but they kept interrupting. Public Works staff told council that many kids were riding not e-bikes but electric motorcycles. The Police Chief, who lives on an East Side pathway, gave on-the-record observations about what his department was seeing. Council members acknowledged the issue was rising but agreed to defer formal policy to another meeting.

- 2 officers now patrol trails on e-bikes issuing tickets
The hack that wasn't supposed to exist
Staff also flagged a growing practice: people disabling the mandatory speed limiter on Class 2 e-bikes that legally cap at 20 mph. The limiter can be defeated not with tools but with a smartphone app — turning a legal bicycle into an unlicensed motorcycle in seconds. This detail would resurface repeatedly over the following months.
4- Class 2 legal cap: 20 mph
- Unlimited mode: 0–30+ mph in 11 seconds
The Data Arrives
Marin's crash dashboard, an ER physician, and a city paying attention
Between November and December 2025, Petaluma's City Council received a concentrated dose of evidence about what e-bike injuries look like in practice. A resident brought Marin County's crash data. An ER physician described treating children. The council listened — but still took no formal action.
The advocate counterpoint: infrastructure, not prohibition
At the November 17 council meeting, bike advocates made the case that the answer to e-bike danger isn't restriction — it's infrastructure. National e-bike sales are up 300% in four years. Petaluma's Active Transportation Plan is being built for a future where bikes are primary transportation. Restricting e-bikes without building safe places to ride them puts vulnerable people in more danger, not less.
16- National e-bike sales up 300%+ in 4 years
- 50%+ of kids choose to bike when school bike trains are organized
Marin's data lands in Petaluma's council chamber
A resident testified at the December 1 council meeting with hard data from Marin County's Health and Human Services bicycle safety dashboard: 85% of all 911 bicycle crash calls for ages 10–15 were e-bike related, with that age group's crash rate five times higher than any other. The app-enabled "unlimited mode" hack was detailed with specificity. The injuries being seen, the speaker noted, were similar to motorcycle crashes — concussions even with helmets, broken pelvic bones.

- Ages 10–15 crash rate: 5x higher than any other age group
An ER physician calls it a public health crisis
At the March 2, 2026 council meeting, a Petaluma-area ER physician who treats children across the Bay Area stood up to speak. E-bikes, he said, were originally designed for older adults who wanted to keep riding. They've since become primarily a vehicle for children — but the injury patterns they're generating in emergency rooms are more like motorcycle crashes than bicycle falls. He called it a public health crisis and urged the city to act at the local level even as state and federal regulators work through the issue.

Petaluma's Winter of Incidents
Two hospitalizations, three citations, and new state laws with teeth
January 2026 compressed months of abstract concern into a single month of concrete incidents. Two juveniles went to the hospital. Three families had their vehicles towed on consecutive downtown days. The story went regional. And for the first time, PPD had real statutory tools to use — because new California laws had taken effect January 1.
Two juveniles hospitalized in one week
On January 7, two juveniles riding unsafely on a single e-bike collided with a parked car near Casa Grande High School. Four days later, two more juveniles on an e-motorcycle were spotted running stop signs near East Washington Place. When officers attempted a traffic stop, the rider sped through another stop sign and nearly struck an oncoming vehicle before losing control on a speed bump. The passenger was uninjured; the driver was taken to Petaluma Valley Hospital with minor injuries. The e-motorcycle was confiscated.
8- 2 juveniles hospitalized in 7 days
- Vehicle confiscated after fleeing officer
Three downtown incidents, three parents cited
Between January 18–19, officers pulled over three separate juveniles riding e-motorcycles in downtown Petaluma. In each case, the juvenile was released to a parent or guardian — and the parent was cited under Vehicle Code 14607 for allowing a minor to operate a motor vehicle on public streets. All three e-motorcycles were towed. The story was picked up by KRON4, the Argus-Courier, and Patch.com.
9- 3 parents cited under VC 14607 in 2 days
- 3 e-motorcycles towed from downtown
Valentine's Day: a juvenile flees officers at Target
On February 14, officers attempted to contact a juvenile rider on an e-motorcycle at the Petaluma Target parking center. The rider fled. He was later stopped on Stuart Drive and cited for evading an officer, driving without a license, failure to provide proof of insurance, and not wearing a helmet before being released to his mother.
10- Charges: evading officer, no license, no insurance, no helmet
What the New Laws Actually Changed
The 2026 California legislative package decoded
Several new laws took effect January 1, 2026, giving officers new tools and closing key loopholes. The package is significant — but it also clarifies what the state is and isn't doing. No minimum age for Class 1 or 2 bikes. No license or insurance requirement for any legal e-bike. The state framework still leaves substantial space, and local jurisdictions retain authority to add restrictions.
AB 875: Officers can now impound on the spot
Before AB 875, officers encountering an underage rider on a Class 3 e-bike or an unlicensed e-motorcycle could issue a citation. After AB 875, they can seize the vehicle immediately, with a minimum 48-hour hold. Completing a CHP-approved safety course may be required as a condition of release. This is the law PPD used throughout January 2026 to tow the downtown e-motorcycles.
15- AB 875: 48-hour minimum impoundment authorized
- Safety course may be required for release
AB 965, AB 1774, AB 544: Closing the loopholes
Three additional laws took effect simultaneously. AB 965 made it illegal to sell a Class 3 e-bike to anyone under 16. AB 1774 extended the ban on speed-modification devices to include apps — directly targeting the iPhone "unlimited mode" hack. AB 544 required rear red lighting on all e-bikes at all hours, giving officers a new low-friction enforcement hook. SB 586 formally defined "off-highway electric motorcycle" as a motor vehicle category subject to OHV rules.
14- AB 965: Selling Class 3 e-bike to under-16 now illegal
- AB 1774: Speed-unlock apps now banned
- AB 544: Rear red light required at all times
What didn't change — and why it matters
No minimum age for Class 1 or 2 e-bikes. No license or insurance required for any legal e-bike. No power cap beyond the existing 750W limit. The NextDoor post that sparked this story worried that Sacramento wants to limit e-bike power so much you can't ride uphill — that's not what the 2026 package does. What it does is draw a clearer line between legal e-bikes and e-motorcycles, and give local agencies tools to enforce that line. Cities can still go further. Several Bay Area jurisdictions are considering age minimums for lower-class bikes.
- No minimum age for Class 1 or Class 2 bikes (statewide)
- No license or insurance required for legal e-bikes
- Local jurisdictions can add restrictions beyond state law
A Year of Circling
How the council has engaged — and what hasn't happened yet
Petaluma City Council has been aware of this issue for over a year. It keeps coming up — in public comment, council member remarks, staff presentations. As of April 2026, no local ordinance or formal policy action has been taken. The debate has lived in public comment and NextDoor rather than in any systematic policy process.
Council members acknowledge the gap — informally
At the March 23 council meeting, multiple members raised e-bikes unprompted during their council reports. Di Carly noted there are no insurance or registration requirements. Cater Thompson mentioned a Davis fatality and pointed to a dent in her family's car from an e-bike collision. The Mayor noted that all council members are getting calls about this. No action was taken.
11, 12- E-bikes raised at 5+ consecutive council meetings with no formal action
State window identified — two months to submit input
At the April 20 council meeting, a council member reported that state e-bike rules are actively moving through Sacramento committees, and that the city has roughly two months to submit formal input. He floated coordination between the Bike and Pedestrian Advisory Committee, staff, and council. No formal referral or vote followed — but the window is open right now.
13- State input window: approximately through mid-June 2026
- PBAC has not formally taken up e-bike policy in any ingested meeting
- Two of nine bills may have died in committee (as of May 2026)
Climate Action Commission: nine state bills in play, city urged to engage now
At the May 14, 2026 Climate Action Commission meeting, a commissioner reported finding nine — possibly more — state bills currently in committee that would significantly tighten the e-bike and e-motorcycle regulatory framework, covering DMV registration, age limits, speed restrictions, insurance mandates, and helmet rules. The commission discussed organizing a joint workshop with transit, PBAC, police, and community stakeholders, but staff cautioned that July may already be too late to influence the legislative process. Staff noted that e-mobility regulation is already in the City Council's goals and priorities, and agreed to bring the topic to staff for coordinated follow-up rather than acting unilaterally.
19, 20- Nine state e-bike bills currently in committee
- Legislative window may close before July CAC meeting
Council member Shribbs organizing bike-community coalition on state bills
At the May 18 City Council meeting, Council Member Shribbs reported in her council member comments that she is actively working on e-bike rules and regulations — specifically, tracking nine state bills moving through Sacramento and convening a group of bike-community stakeholders to develop a Petaluma position. She noted two of the nine bills may already have died in committee, but that significant legislative activity remains. She invited interested parties to join the effort.

Two Concerns That Aren't Actually in Conflict
Safety vs. active transportation — and why the framing is wrong
The debate in Petaluma isn't simply 'regulate more' versus 'regulate less.' It's more complicated. The real distinction — which enforcement has begun to draw but policy hasn't formalized — is between legal e-bikes and e-motorcycles; between compliant use and modified or unlicensed use. The NextDoor poster and the ER physician are both right. They're describing different vehicles.
The NextDoor post that started this story
A Petaluma resident posted on NextDoor warning about a proposed e-bike law and urging neighbors to speak at an upcoming meeting. The post correctly identified several real issues: existing laws are unenforceable, speed limit signs might be more effective than blanket restrictions, and e-bikes that can exceed 30 mph are already legally registerable as motorcycles. The post also worried about power limits that would make hills impossible — a concern about legal e-bikes, not the electric motorcycles that have actually been the focus of PPD enforcement.
- Legal e-bikes: no power restriction proposed
- E-motorcycles: already legally classified as motor vehicles
Helen Putnam: where the categories collide on trails
A Downtown Petaluma resident described the on-the-ground reality in Helen Putnam Regional Park: legal e-bikes (Class 1, no throttle) are allowed on trails. E-motos that can exceed 30 mph are not — they're motorcycles. But enforcement is thin and the distinction is invisible to most trail users. The resident, recovering from hip surgery, described being frightened multiple times by fast-moving electric bikes on narrow trail sections. The county or park district would need to act for park enforcement — the city can address its own greenways and pathways.
18- Class 1 e-bikes: allowed on most shared trails
- E-motorcycles (>30 mph): already prohibited on trails — enforcement gap
Five Things Petaluma Could Do
The levers that exist — and the window that's closing
With new state tools in hand and a Sacramento input window open through roughly mid-June 2026, Petaluma has more leverage than it has used. None of these require inventing new categories or restricting legal e-bikes. They require precision: targeting the enforcement gap, submitting a formal position to the state, and giving the PBAC a real mandate.
1. Submit formal comment to the state — before mid-June
The April 20 council discussion identified a narrow window to influence state legislation currently in committee. A formal council position — particularly supporting stronger app-modification enforcement and clearer e-motorcycle classification standards — gives Petaluma's documented experience useful weight in Sacramento. This requires only a staff memo and a council vote.
13- Window closes: approximately mid-June 2026
2. Local ordinance: e-motorcycles on city pathways
The Petaluma Greenway and city-owned shared-use paths are within council authority. An ordinance explicitly prohibiting vehicles that exceed the Class 3 speed threshold (28 mph) from these paths — with posted signage and defined enforcement authority — would close the gap between what's technically illegal and what PPD can act on. Helen Putnam trails would require county/park district action separately.
3. Age minimums for lower-class bikes on pathways
California sets no minimum age for Class 1 and 2 e-bikes statewide. Cities can. Several Bay Area jurisdictions are considering age-based restrictions for shared-use pathways specifically. A Petaluma restriction — even a modest one, such as requiring adult supervision for riders under 12 on certain pathways — would align policy with what enforcement is already trying to accomplish informally.
- State sets no minimum age for Class 1 or 2 e-bikes
- Cities may impose local restrictions
4. Retailer partnership and point-of-sale education
Marin's response to the same problem included working with local retailers to ensure buyers understand what class of vehicle they're purchasing and what the age and use rules are. Petaluma Motor Wheel and other local retailers could be partners in a voluntary program. The goal: no family walks out of a store with an e-motorcycle thinking they bought a bicycle.
5. Formally refer e-bike policy to PBAC with staff support
The Pedestrian and Bicycle Advisory Committee is the natural home for this work — but the council transcripts show the issue has lived almost entirely at the council level through public comment. A formal referral with staff support would let PBAC develop a comprehensive local policy framework: pathway rules, age guidelines, signage standards, and a position on state legislation. Without a mandate and resources, PBAC cannot act.
- PBAC has no formal e-bike referral as of April 2026
