Riding with kids on an e-bike is becoming more popular across California — but the laws around ages, passengers, and child carriers aren’t always straightforward. To help make things clearer, here’s a simple, scan-friendly chart summarizing the rules, followed by a full breakdown of what California parents and riders need to know.

(Local cities/counties can add stricter rules — always verify your area.)

What the Chart Means for California Riders

While state law sets a foundation, California allows cities and counties to add their own restrictions. This means passenger rules — especially those involving kids — can vary depending on where you ride. Below, you'll find a complete, easy-to-understand guide so you can ride safely and legally anywhere in the state.

1. E-Bike Classes & Rider Age Requirements

1.1 Class Overview

• • Class 1: Pedal-assist only, max 20 mph

  • Class 2: Throttle + pedal-assist, max 20 mph

  • Class 3: Pedal-assist only, up to 28 mph, speedometer required

1.2 Minimum Age

·         Class 3: Riders must be 16 or older

·         Class 1 & 2: No statewide minimum

o    Some cities ban riders under 12 from Class 1 or 2

·         Helmet rules:

o    Mandatory for riders under 18 on any e-bike

o    Required for all riders on Class 3

2. Passenger & Child-Carrier Regulations Explained

2.1 Carrying Passengers

California allows passengers only if the bike is designed for one, meaning:

·         It has an extra permanent seat, or

·         A certified child carrier

No seat = no passenger, even on cargo or long-tail bikes.

2.2 Child Seats

If you plan to ride with a younger child:

·         Use a bike-rated child carrier

·         Many CA cities require the child to be:

o    Under 4 years old, or

o    Under 40 lbs

·         Child must wear a helmet

·         Child must be secured and cannot move freely or grab the rider

2.3 Why Class 3 Usually Prohibits Passengers

Class 3 bikes:

·         Are faster (up to 28 mph)

·         Require a minimum rider age of 16

·         Are often restricted to single-rider use only

·         Are banned from carrying children in many jurisdictions

If you're considering family riding, Class 1 or Class 2 will almost always be the safer — and legal — choice.

3. Local Regulations: Why They Matter

California allows cities to create their own e-bike rules. That means:

·         One city may allow child seats on Class 1

·         Another might ban passengers entirely

·         Others might restrict young riders or require extra safety equipment

Before riding with kids, check rules for:

·         Your home city

·         The trail or bike path you use

·         The county (some have separate regulations)

4. Safe Riding Tips for Parents

When carrying a child on an e-bike:

·         Use a stable bike (cargo e-bikes are safest for kids)

·         Keep speeds low, even on Class 1/2

·         Double-check mounting hardware before each trip

·         Practice riding with weight before adding your child

·         Choose low-traffic routes and protected bike lanes whenever possible

5. FAQ: California E-Bike Age & Child-Passenger Rules

Q1: Can my 10-year-old ride a Class 1 e-bike alone?

Yes under state law — but many cities prohibit riders under 12, so check your local ordinance.

Q2: Can I carry a toddler in a child seat?

Yes, if:

·         Your e-bike has a designated child-seat mounting point

·         The child is within the seat’s age/weight limits

·         You’re riding a Class 1 or Class 2 e-bike

·         Your city permits it

Q3: Can I take a child on a Class 3 e-bike?

Usually no. Class 3 bikes are generally restricted to one rider and cannot carry kids in most California jurisdictions.

Q4: Do child passengers need helmets?

Yes. All passengers under 18 must wear a properly fitted helmet.

Q5: Is it legal to modify an e-bike to go faster when carrying a child?

No. It becomes a motor vehicle requiring registration and is unsafe for child transport.
