In July 2025, a 12-year-old boy ran a red light in Yorba Linda on a device his family called an e-bike, and a Honda Civic that tried to swerve could not avoid him. The boy suffered a fractured skull, intracranial bleeding, a broken wrist, and a fractured femur, all while wearing a helmet that investigators could not confirm was properly secured. This month, the Orange County District Attorney charged the boy’s father with felony child endangerment and abuse, not simply because a child was hurt, but because the device his son was riding does not qualify as an e-bike under California law.¹ It qualifies as a motorcycle, and his father allegedly helped him modify it into one.
Every parent in Orange County who has bought or modified an electric bike for a child should pay close attention to this case, and so should every accident victim who has been struck by one of these devices on a public road. California law treats modified e-bikes very differently than most people assume, and the consequences, both criminal and civil, are severe.
What Happened in Yorba Linda
The Orange County District Attorney’s office announced on March 4, 2026, that Richard John Eyssallenne, 39, of Yorba Linda, pleaded not guilty to one felony count of child endangerment and abuse and one misdemeanor count of contributing to the delinquency of a minor. He faces up to six years in state prison if convicted on all counts.²
According to prosecutors, Eyssallenne gave his 12-year-old son a 2024 Talaria XXX as a Christmas gift. The device was marketed as an e-bike, but father and son then modified it: they replaced the pedals with motorcycle pegs and removed the speed governor, rewiring the motor so it could reach speeds up to 60 miles per hour. The device’s motor was rated at 750 watts with a peak output of 5,000 watts.³
The boy had already been cited in December 2024 for illegally riding the device, and it had been impounded. In January 2025, the father brought both of his sons, ages 10 and 12, to an e-bike safety course hosted by Yorba Linda Police Services. Six months later, on July 20, 2025, the 12-year-old ran a red light at Via Lomas De Yorba West and La Palma Avenue and was struck by a car.⁴
How California Draws the Line Between an E-Bike and a Motorcycle
This distinction trips up more families than almost any other area of California vehicle law. Under California Vehicle Code § 312.5, an “electric bicycle” must meet three requirements: it must have fully operable pedals, an electric motor of less than 750 watts, and it must fall into one of three speed-limited classes. Class 1 and Class 2 are capped at 20 mph; Class 3 is capped at 28 mph and restricted to riders 16 and older.⁵
The moment a device fails any of those tests, it stops being an e-bike under California law. If the pedals are removed or replaced with pegs, if the motor exceeds 750 watts, or if the device is modified to exceed its class speed limit, the state may treat it as a “motor-driven cycle” (Vehicle Code § 405) or a full “motorcycle” (Vehicle Code § 400), depending on its power and speed.
That reclassification changes everything. The rider now needs a motorcycle license from the DMV (called an M1 or M2 endorsement), registered plates, and insurance, just like any other motorcycle on the road. Riding without those credentials is illegal, and allowing a child under 16 to do so can result in criminal charges.⁶
In the Yorba Linda case, law enforcement inspected the Talaria XXX after the crash and determined it did not qualify as an e-bike under any class. The device was legally a motorcycle.
Filing Deadlines That Could Cost You Your Case
Whether you are the parent of a child injured on a modified e-bike or a driver or pedestrian struck by one, the clock starts running immediately after the accident.
Under California law (Code of Civil Procedure § 335.1), you have two years from the date of the injury to file a personal injury lawsuit. The same two-year deadline applies to wrongful death claims. If you miss it, even by a single day, the court will almost certainly refuse to hear your case, no matter how strong it is.
An even shorter deadline catches many families off guard. If a government agency played any role in the accident (for example, a city that failed to maintain a dangerous road, a school zone with no enforcement, or a hazard on a public park or trail), you must file a formal claim with that government entity within just six months (Government Code § 911.2). If you skip this step, you may permanently lose the right to include that government defendant in your case.⁷
Evidence also disappears fast. Dashcam and surveillance footage from nearby businesses often overwrites within days. Crash scene markings fade. Electronic data from the e-bike itself, including speed logs and motor output data, can be lost if the device is returned to the owner without preservation. An attorney can send legal preservation letters to all relevant parties immediately after the crash to protect this evidence before it vanishes.
Who Can Be Held Liable in a Modified E-Bike Accident
E-bike and e-motorcycle accidents often involve more potentially responsible parties than a typical car crash. In a case like the Yorba Linda incident, liability analysis could extend in several directions.
The parent or guardian who purchased, modified, or allowed the minor to ride an illegally classified device may face both criminal charges (as we have seen here) and civil lawsuits for failing to properly supervise their child. A driver who strikes a rider may also share some fault depending on the circumstances. California follows a rule called “pure comparative negligence” (established in Li v. Yellow Cab Co., 13 Cal.3d 804, 1975), which means that even if an injured person is partially to blame for the accident, they can still recover compensation. The amount is simply reduced by their share of the fault. For example, if a rider is found 30% at fault and the total damages are $100,000, that rider could still recover $70,000.⁸
The manufacturer of the device may face product liability claims if the e-bike was designed in a way that made it easy to modify beyond legal limits, or if the marketing materials misrepresented the device’s classification. The Orange County DA specifically noted that many electric motorcycles are marketed as e-bikes despite failing to meet the legal definition.
California’s SB 1271, effective January 2026, now makes it a crime to advertise, sell, or label a motor vehicle as an “electric bicycle” if it does not meet the specifications in CVC § 312.5.⁹ In some cases, a retailer who sold the device without verifying its classification, or who sold a Class 3 e-bike to a minor (prohibited under current law), could also share liability.
What Compensation Victims Can Pursue
A person injured in an e-bike or e-motorcycle accident can generally pursue two types of compensation. Economic damages cover the financial losses you can put a number on: emergency room bills, surgery, hospitalization, physical therapy, prescription costs, lost wages while you recover, and reduced earning ability if the injuries are permanent. Non-economic damages cover the losses that do not come with a receipt but are just as real: physical pain and suffering, emotional distress, loss of enjoyment of life, and the lasting impact on your daily routine and relationships.
In the Yorba Linda case, the boy’s injuries (skull fracture, intracranial bleeding, fractured femur, broken wrist) will likely require extensive rehabilitation and could affect his development for years. These are the types of catastrophic injuries that demand careful, long-term damages analysis rather than a quick insurance settlement.
When a modified e-bike or e-motorcycle is involved, insurance coverage becomes more complicated. Standard e-bike riders are not required to carry auto insurance, but once a device is reclassified as a motorcycle, the rider (or the rider’s parent) is legally required to carry motorcycle insurance.
If they do not have it, the injured victim may need to turn to their own uninsured motorist coverage under California Insurance Code § 11580.2.
Six Steps to Take After an E-Bike or E-Motorcycle Accident
1. Call 911 immediately. Request police and paramedics even if injuries appear minor. Symptoms of traumatic brain injury often do not surface for hours or days after impact.
2. Document the device. Photograph the e-bike or e-motorcycle from multiple angles, including the motor, pedals (or lack of pedals), brand name, and any visible modifications. This evidence is critical for classification disputes later.
3. Get a medical evaluation the same day. Insurance companies routinely argue that delayed treatment means the injuries were not serious. A same-day medical record protects your claim.
4. Do not give a recorded statement to any insurance company before speaking with an attorney. Early statements made before the full extent of injuries is known can be used to minimize your recovery.
5. Preserve all evidence. Do not allow the e-bike or e-motorcycle to be returned, sold, repaired, or discarded. It is a key piece of evidence for proving classification, modification, and liability.
6. Contact a personal injury attorney within days. An attorney can send preservation letters, retain accident reconstruction experts, and identify every potentially liable party before evidence is lost.
Frequently Asked Questions About E-Bike Accidents in California
Is my child’s e-bike actually legal in California?
It depends on the specifications. If the device has fully operable pedals, a motor at or below 750 watts, and does not exceed its class speed limit, it qualifies as an e-bike under CVC § 312.5. If any of those elements have been modified (pedals removed, governor bypassed, motor rewired for higher output), the device may be reclassified as a moped, motor-driven cycle, or motorcycle, each of which carries licensing, registration, and insurance requirements.
Can a parent face criminal charges for letting a child ride a modified e-bike?
Yes. As this Yorba Linda case demonstrates, the Orange County District Attorney charged the father with felony child endangerment under Penal Code § 273a(a) and contributing to the delinquency of a minor. CVC § 14607 also authorizes citations to parents or guardians for certain e-bike violations committed by their minor children.¹⁰
If my child was injured on an e-bike, can I sue the manufacturer?
Potentially. California product liability law allows claims against manufacturers when a product is defectively designed or when marketing materials misrepresent what the product is. If a device marketed as an e-bike is easily modified to exceed legal speed and power limits, or if it was sold without proper classification labeling, the manufacturer and retailer may share liability for resulting injuries.
What if I was hit by someone riding a modified e-bike?
You have the same right to pursue a personal injury claim as you would in any vehicle accident. The rider (or the rider’s parents, if the rider is a minor) may be liable for negligence. You may also have claims against the device manufacturer, the retailer, or a parent who allowed illegal operation. Your own uninsured motorist coverage may apply if the rider lacked insurance.
How does California’s comparative negligence rule apply to e-bike crashes?
California uses a system called “pure comparative negligence,” which means you do not lose your right to compensation just because you were partially at fault. Instead, your recovery is reduced by your share of the blame. If you were 20% at fault and your damages total $50,000, you could still recover $40,000. In the Yorba Linda crash, the Honda Civic driver attempted to avoid the boy, and there is no indication the driver bore any fault, but this analysis depends on the specific facts of every case.
What new California laws affect e-bikes in 2026?
SB 1271, effective January 1, 2026, requires all e-bike batteries sold in California to be tested and certified by accredited laboratories (such as UL 2849 certification). The law also makes it illegal to advertise, sell, or label a motor vehicle as an “electric bicycle” if it does not meet the legal definition. Assembly Bill 544 requires e-bikes to have a rear red reflector or light at all times, not just at night. Assembly Bill 875 gives law enforcement expanded authority to impound electric vehicles with fewer than four wheels that do not meet the e-bike definition.¹¹
The Bigger Picture: E-Bike Safety in Orange County
The Yorba Linda case is not an isolated incident. Children’s Hospital of Orange County treated 201 e-bike trauma patients in 2025, up from 125 the year before.¹² Newport Beach police recently conducted enforcement operations near schools, issuing dozens of citations, impounding three e-bikes, and arresting two juveniles who fled on illegally modified e-motorcycles in a single day.
Police departments across Orange County, including Huntington Beach, are holding safety seminars for families, but the gap between education and enforcement remains wide.
The law is catching up, but it has not caught up yet. Until it does, the responsibility falls on parents to verify that the device in their garage actually meets the legal definition of an e-bike. For accident victims, these devices can cause catastrophic injuries that deserve the same serious legal response as any motor vehicle crash.
