E-Bike Accidents in California

California sorts electric bicycles into three classes by how the motor works and how fast it assists. Vehicle Code section 312.5 sets those definitions. The class your bike falls into affects where you were allowed to ride, whether a helmet was required, and how an insurance company will try to argue fault after a crash.

The Statute

Class 1, Class 2, and Class 3 Under Section 312.5

Vehicle Code section 312.5 says an electric bicycle is a bicycle equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power. No working pedals, or a bigger motor, and it is not an electric bicycle under California law no matter what the seller called it. From there the statute draws three classes, separated by whether the motor can move the bike on its own and the speed at which it stops helping.

• Class 1. A motor that provides assistance only when the rider is pedaling, that is not capable of exclusively propelling the bicycle, that ceases to provide assistance at 20 miles per hour, and that cannot assist to reach speeds greater than 20 miles per hour.
• Class 2. A motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches 20 miles per hour. This is the throttle class.
• Class 3. A motor that provides assistance only when the rider is pedaling, that is not capable of exclusively propelling the bicycle, that ceases to provide assistance at 28 miles per hour, and the bike must be equipped with a speedometer.

One narrow exception sits inside the statute. A class 1 or class 3 electric bicycle may have start assistance or a walk mode that runs on motor power alone up to 3.7 miles per hour. That does not turn a pedal assist bike into a throttle bike.

Section 312.5 also requires a permanently affixed label on each electric bicycle showing the classification number, the top assisted speed, and the motor wattage, in Arial font of at least 9 point type. That label is usually the fastest way to answer the class question after a crash, so photograph it early.

Modifications matter. Under the statute, a two or three wheeled electric vehicle built to be modifiable past 20 miles per hour on motor power alone or past 750 watts, one actually modified to do either, and one modified to have its pedals removed, are not electric bicycles and may not be sold or labeled as electric bicycles. A modified bike can fall outside the e-bike rules altogether.

Where You May Ride

Roads, Bike Paths, and Local Control

Section 312.5 says a person riding an electric bicycle is subject to the rules that govern bicycles, in the article of the Vehicle Code beginning at section 21200. Under section 21200, a person riding a bicycle on a highway has all the rights and all the duties of the driver of a vehicle.

Bikeways come in four types under Streets and Highways Code section 890.4. A Class I bikeway is a bike path on a completely separated right of way. A Class II bikeway is a striped bike lane. A Class III bikeway is a signed bike route shared with other traffic. A Class IV bikeway is a cycle track or separated bikeway next to a roadway. Bikeway classes and e-bike classes are two different systems that share the word class.

Path access is decided locally. Vehicle Code section 21207.5 lets the local authority or public agency with jurisdiction over an equestrian, hiking, or recreational trail prohibit an electric bicycle or any class of electric bicycle on that trail by ordinance, and lets the Department of Parks and Recreation do the same for a path or trail within its jurisdiction. Vehicle Code section 21206 separately preserves local power to regulate bicycle operation on pedestrian and bicycle facilities. Access therefore depends on where you were, so signs and local rules are worth collecting early.

After A Crash

Why Your Class Matters, and Why It Does Not Decide the Case

Classification matters after a crash for three practical reasons.

First, it bears on where you were allowed to be. If the defense argues you had no business on a particular path, the answer comes from the class of the bike, the class of the facility, and the rule that applied at that spot. That is a factual question with a documentary answer.

Second, it bears on whether a helmet was required. Vehicle Code section 21213 provides that a person under 16 years of age shall not operate a class 3 electric bicycle, and that no one may operate or ride as a passenger on a class 3 electric bicycle on a street, bikeway, or public bicycle path or trail unless wearing a properly fitted and fastened bicycle helmet meeting ASTM or CPSC standards. Section 21212 separately requires a helmet for anyone under 18 riding a bicycle. So a class 3 rider of any age needs a helmet, and every rider under 18 needs one regardless of class.

Third, it shapes the fault argument. Under Evidence Code section 669, a person is presumed to have failed to exercise due care if they violated a statute, the violation proximately caused the injury, the injury was the kind the statute was meant to prevent, and the injured person was in the class the statute protects. That presumption cuts both ways, applying to a driver who ran a red light as much as to a rider who broke a class rule, and section 669 says it is rebuttable.

A helmet or class violation does not by itself decide a claim. Every element of section 669 has to be met, including that the violation actually caused the harm and that the statute was aimed at that kind of harm. A helmet has nothing to do with whether a driver turned left across your path. The same reasoning applies to a standard bike claim, covered on our page about bicycle accidents.

California uses comparative fault, so a rider found partly at fault has their recovery reduced by that share rather than barred. Civil Code section 1431.2 governs how one category of damages is split among defendants. In any action for personal injury, property damage, or wrongful death based on principles of comparative fault, liability for non economic damages is several only and not joint, and each defendant is liable only for the amount allocated in direct proportion to that defendant’s percentage of fault. The statute defines economic damages as objectively verifiable monetary losses such as medical expenses and lost earnings, and non economic damages as subjective losses such as pain and suffering.

Who Pays

Which Insurance Policies Can Respond

If a car hit you, the driver’s auto liability coverage is the first place to look. You do not need to own a car or carry insurance to make that claim. The policy responds to the harm the driver caused, whether you were on an e-bike or in a vehicle.

Uninsured and underinsured motorist coverage is the second layer, and riders most often overlook it. Insurance Code section 11580.2 requires that coverage in California auto bodily injury liability policies unless it is deleted in writing. Under that section, when the named insured is an individual, the insured includes the named insured, the spouse, and resident relatives of either, covered while occupants of a motor vehicle or otherwise. That last phrase is why a household auto policy can reach a rider who was on an e-bike and never near the insured car. If the driver who hit you had no coverage, too little coverage, or left the scene, find your household auto declarations page right away. Coverage still turns on the policy language, including notice and consent conditions.

Homeowners and renters policies matter in a different way. They are governed by their own terms rather than by any statute setting e-bike coverage, so the answer is in the document. If another rider on an e-bike hit you, that person’s homeowners or renters liability coverage may pay for the injury. If you are accused of causing one, your own policy may provide a defense and coverage. Many such policies exclude motorized vehicles, and whether an electric bicycle falls inside that exclusion turns on how the policy defines the term. Read the definitions and exclusions rather than assuming.
