San Diego E-Bike Laws and Regulations

San Diego Electric Bicycle Safety Program

California passed a law implementing the San Diego Electric Bicycle Safety Pilot Program which allows San Diego County, or any cities in the county, to ban riders of e-bikes if they are younger than 12 years old.

‍

‍

The pilot program is scheduled to run from Jan. 1, 2025-Jan. 1, 2029. The pilot program was implemented after an increase in the number of collisions involving e-bikes across the state of California. Under the program, children under the age of 12 would no longer be permitted to operate electronic bikes. City Councils in San Diego, Encinitas and Solana Beach are considering the program. Additionally, the city of Coronado is considering a similar ban on riders younger than 12.

In addition to the pilot program, schools across San Diego and California are making efforts to educate students on safety and e-bikes.

Minimum Rider Age & Licensing (New as of 2025)

California now requires that anyone using a throttle‑only e‑bike (Class 2) be at least 12 years old. Also, all e‑bike riders—even for pedal‑assist bikes—must carry a valid driver’s license, or, for those under 16 or unlicensed, a state‑issued bike safety certificate from CHP. Free online training is available for minors to meet this requirement.

Note: The CHP offers a free bike certification course for minors under 16 to meet this requirement.

Understanding the Classification of E-Bikes

Many states have adopted a universal classification of electronic bikes. This three-tier-system provides guidance on where bikes can be ridden and other restrictions.

• Class 1: pedal‑assist up to 20 mph
• Class 2: pedal‑assist or throttle to 20 mph
• Class 3: pedal‑assist only up to 28 mph (no throttle)

‍

‍

If your e-bike exceeds these specifications—for example, if it’s capable of speeds over 28 mph without pedaling or has a more powerful motor—it may be considered a motor-driven cycle, moped, or even a motorcycle, which would require DMV registration, a valid driver’s license, insurance, and potentially turn signals and brake lights.

Be Cautious With Modifications:

Many e-bike riders unknowingly make their bikes non-compliant by modifying the motor or removing pedal assist, especially with throttle-enabled bikes. If your e-bike is no longer classified as Class 1, 2, or 3, you could face citations for operating an unregistered motor vehicle or even have your bike impounded.

‍

Helmet Requirements

Users aged 17 and under must wear a helmet when operating a Class 1 or 2 e-bikes. Class 3 bikes require helmets and may not be used by people under age 16. (California Vehicle Code § 21212) There are no age restrictions on who can use a Class 1 or 2 electronic bike, unless specified by local laws.

‍

Where E-Bikes are Permitted to Travel

Class 1 and 2 bikes are permitted to travel in the same places as regular bikes unless there is a sign prohibiting electric bikes. Class 3 bikes (along with gas-powered bikes) are not allowed on trails or bike paths unless local rules say otherwise.

If you are biking slower than traffic, you should ride in the bike lane. You are permitted to leave the bike lane to turn left, pass someone, avoid something in the road or avoid cars turning right

How Can Cyclists Stay Safe?

• Wear a Helmet: Helmets reduce the risk of serious head injuries in a crash.
• Use Reflective Gear and Lights: For cyclists riding during low-light conditions, using bright lights and reflective clothing can help make them more visible to drivers.
• Stay in Bike Lanes: Whenever possible, use designated bike lanes. These lanes provide a safer space for cyclists, reducing the chances of an accident.
• Ride in a Group: Riding in a group makes you more visible to drivers. 
• Obey Traffic Laws: Cyclists should follow the same traffic laws as drivers, stopping at red lights and stop signs and yielding when required.
• Stay Alert: Avoid distractions like phones and headphones, which can impair awareness on the road.

If You're Injured in an E-Bike Accident in San Diego

California's e-bike classification system doesn't just affect where you ride — it directly affects your legal rights if you're hurt in a collision. The class of e-bike you were riding, whether you had a valid safety certificate, and whether the other party was a motorist, property owner, or equipment manufacturer all shape which legal claims are available to you.

When a Driver Causes an E-Bike Accident

Most e-bike collisions in San Diego involve a motor vehicle — a driver who fails to yield, opens a car door into a cyclist, or turns without checking a bike lane. When a driver is at fault, your claim proceeds like any bicycle accident case: you are entitled to compensation for medical expenses, lost wages, pain and suffering, and property damage (including the e-bike itself). California's comparative fault rules apply, so even if you contributed partially to the crash, you can still recover — your award is reduced proportionally.

Defective E-Bikes and Product Liability

E-bike battery fires, throttle malfunctions, and brake failures are an emerging category of product liability cases. Unlike traditional bicycle defects, e-bike defects can cause fires, loss of control at speed, and severe burns. If your e-bike failed mechanically and caused your injuries, the manufacturer or importer may be strictly liable under California products liability law — regardless of whether you followed all the rules of the road.

E-Bike Accidents Involving Minors

Given the new minimum age requirements under California law, accidents involving underage e-bike riders raise additional legal questions — including whether a parent, retailer, or property owner bears responsibility for allowing an underage rider access to a Class 2 or Class 3 e-bike. If a child was injured riding an e-bike provided by a school, employer, or rental company that failed to verify age or provide safety instruction, those parties may share liability.
