California E-Bike Laws Overview
California allows electric bikes that meet the state’s three-class system and safety rules.
As of 2025 and 2026, a legal e-bike in California must:
- Have fully operable pedals
- Use a motor rated at 750 watts or less
- Follow class-based speed limits
- Comply with battery safety certification rules starting in 2026
Class 3 e-bikes are pedal-assist only, stop assisting at 28 mph, require helmets for all riders, and are limited to riders age 16 and older.
E-bikes that exceed these limits may be classified as motor vehicles and can be ticketed or impounded.

How California Defines an E-Bike in 2025
Under California law, an electric bicycle must:
- Have fully operable pedals
- Use an electric motor rated at 750 watts or less
If a bike has no pedals or exceeds 750 watts, it is not an e-bike under California law. It may instead be classified as a moped or motor-driven cycle, which comes with different licensing, registration, and insurance requirements.
For a deeper breakdown of speed limits and legal classifications, see our Class 3 e-bike guide.
E-Bike Classes in California (Updated Chart)
California still uses the three-class system, but the new rules clarify throttle limits and motor operation.
| Class | Motor Speed Limit | Pedal Assist | Throttle | Minimum Age | Helmet Required |
|---|---|---|---|---|---|
| Class 1 | 20 mph | Yes | No | None | Under 18 |
| Class 2 | 20 mph | Yes | Yes | None | Under 18 |
| Class 3 | 28 mph (pedal assist only) | Yes | No throttle | 16+ | Yes, all riders |
Important Notes
- Class 3 e-bikes cannot include a throttle that moves the bike without pedaling
- Walk-assist throttles (around 3.7 mph) are allowed
- Any e-bike using a throttle above 20 mph cannot be sold as an e-bike in California
- These rules are being enforced more strictly
Some online retailers still advertise Class 3 bikes with throttles. This is incorrect under California law.
Class 3 Throttles: Clearing Up the Confusion
Some online retailers still advertise Class 3 bikes with throttles. This is incorrect.
California law has always required that Class 3 e-bikes:
- Use pedal assist only
- Have no throttle that propels the bike
- Stop assisting at 28 mph
- Allow riders 16 and older only
- Require helmets for every rider
If a bike has a throttle and goes over 20 mph by motor alone, it does not qualify as an e-bike under California rules.
Modifying Your E-Bike
SB 1271 sets clear limits on e-bike modifications.
You cannot legally:
- Modify a bike to exceed 20 mph under motor power alone
- Increase the motor beyond 750 watts
- Sell or advertise a modified bike as an e-bike
Modified high-powered bikes may be reclassified as motor vehicles. This increases the risk of citations, fines, and impoundment.

Battery Certification Rules (Important for 2026)
Starting January 1, 2026, all e-bike batteries sold in California must be certified by a recognized safety testing lab, such as UL.
Why This Matters
- Battery fires have increased in urban areas
- Certified batteries reduce overheating and fire risks
- Many reputable brands already comply
Additional clarifications include:
- Batteries must be properly labeled to show certification
- Selling, leasing, or distributing non-certified batteries or e-bikes is prohibited
- By January 1, 2028, these rules will also apply to rental e-bikes
If possible, choose an e-bike with a certified battery now so you are prepared.
For more detail, see our e-bike battery safety and capacity guide.
Rear Red Light or Reflector Required at All Times
Starting in 2026, all e-bikes must have a red rear reflector or a red rear light with a built-in reflector.
This applies at all times, not just at night.
What riders should know:
- Solid or flashing red lights are allowed
- Applies to all e-bike classes
- Most modern e-bikes already meet this requirement
Helmet Violations for Minors Can Be Cleared With a Safety Course
If a minor receives a helmet citation while riding an e-bike, California now allows an alternative to paying a fine.
Instead, the minor may be able to:
- Complete a California Highway Patrol-approved online e-bike safety course
This rule focuses on education while keeping helmet rules in place.
Reminder:
- Riders under 18 must still wear helmets on all e-bike classes
Police Can Impound Illegal High-Powered E-Bikes
Law enforcement now has clearer authority to impound vehicles with fewer than four wheels that do not meet California’s e-bike definition.
This includes bikes that:
- Exceed 20 mph under motor power alone
- Exceed 750 watts
- Are improperly modified
- Are operated illegally or by underage riders
This rule targets unsafe and mislabeled high-powered e-bikes, especially on shared paths.
Where You Can Ride
Riding access depends on e-bike class.
Class 1 and Class 2
- Bike paths
- Most multi-use trails
- City bike lanes
Class 3
- Bike lanes
- Roads
- Often restricted from shared-use trails
Local cities and counties may set stricter rules. Always check local signage and ordinances.
You can also reference our California e-bike trail access guide for city-level examples.
Age and Helmet Rules
Class 3
- Rider must be 16 or older
- Helmet required for all riders
Class 1 and Class 2
- No minimum age
- Riders under 18 must wear a helmet
About SB 1271
Senate Bill 1271 took effect January 1, 2025. It updates e-bike definitions, clarifies the three classes, and sets stronger safety standards for batteries. These updates are part of California’s effort to keep pace with the growing number of e-bikes on roads and trails.

Proposed 2026 Law for Registration & License Plates
In February 2026, the California Legislature introduced Assembly Bill 1942 (AB 1942), officially titled “Electric bicycles: registration and special license plates.” This bill would require Class 2 and Class 3 e-bikes to be registered with the California Department of Motor Vehicles (DMV) and to display a special license plate issued by the DMV if it becomes law. Under the proposal:
- Owners would need to register their Class 2 and Class 3 electric bicycles with the DMV and obtain a plate tied to the bike’s serial number.
- The license plate would need to be affixed to the rear of the e-bike and be clearly visible while riding.
- Riding a Class 2 or Class 3 e-bike without the required registration or plate could be considered an infraction with fines for non-compliance.
- The bill would also create an Electric Bicycle Registration Fund to administer and regulate the program.
As of early 2026, AB 1942 is still in the legislative process and has not yet become law. Riders do not currently need plates or DMV registration under existing California law, but this proposal could change how e-bikes are treated if passed.
For the official bill text, see the California Legislature Bill Text for AB 1942
What You Should Do Now
- Confirm your e-bike class
- Make sure your throttle setup is compliant
- Avoid illegal modifications
- Choose certified batteries
- Ensure your bike has a rear red light or reflector
- Follow helmet and age rules
- Check local trail and city regulations
My Take
California’s updated e-bike laws focus heavily on safety, especially as faster and more powerful e-bikes become more common on shared paths. The stricter enforcement around throttles, motor limits, and battery certification makes sense given the rise in accidents and battery fires.
For most riders using standard Class 1 or Class 2 e-bikes, these changes will not affect day-to-day riding. The biggest risks are buying mislabeled bikes online or modifying a bike beyond legal limits without realizing the consequences.
If you stick with a compliant e-bike from a reputable brand, California remains one of the more e-bike-friendly states.
Final Thoughts
California’s e-bike laws are designed to keep riders safe while preserving access for legal electric bicycles. Standard e-bikes under 750 watts remain legal without licenses or registration, but enforcement is stricter for high-powered and modified bikes.
Knowing your e-bike class, avoiding illegal modifications, and choosing certified batteries will help you ride confidently and stay compliant.
