How Does Electric Bikes Define in California?

An electric bicycle is a bike with fully operable pedals, a battery, and an electric motor. Electric bicycles in California are subject to the same regulations as traditional bicycles. Both have to obey the same traffic rules on the roads.

According to Senate Bill No. 1271, CHAPTER 791, Ebikes must not exceed 750W and 28 mph on level ground. The motor has to disengage when the brakes are applied. There should also be a switch or mechanism on the bike to control the motor's function. Three Ebike classes are explained below.

Class 1 Ebikes

A “class 1 electric bicycle,” or “low-speed pedal-assisted electric bicycle,” is a bicycle equipped with 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 when the bicycle reaches the speed of 20 mph, and that is not capable of providing assistance to reach speeds greater than 20 mph.

Class 2 Ebikes

A “class 2 electric bicycle,” or “low-speed throttle-assisted electric bicycle,” is a bicycle equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 mph.

Class 3 Ebikes

A “class 3 electric bicycle,” or “speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, that is not capable of exclusively propelling the bicycle, and that ceases to provide assistance when the bicycle reaches the speed of 28 mph, and equipped with a speedometer.

Note: A class 1 or class 3 electric bicycle may have start assistance or a walk mode that propels the electric bicycle on motor power alone, up to a maximum speed of 3.7 mph.

Do You Need a License to Ride an Ebike in California?

No, a rider or operator license is not required to ride an electric bike in California. In addition, unlike a moped or motorcycle, an Ebike does not require registration or a license plate.

However, using an electric bike is subject to the same traffic laws as riding a traditional bike. You must abide by all regulations, including traffic signals, stop signs, and speed restrictions.

Are There Any Age Restrictions for Riding an Ebike in California?

There are no age restrictions on Class 1 and Class 2 Ebikes. Riders must be at least 16 to operate a Class 3 Ebike. All riders under 18 must wear a helmet on any type of bike, motorized or not.

Should I Wear a Helmet to Ride an Ebike in California?

You must wear an approved helmet while riding an electric bicycle in California if you are 17 and under. If you are 18 and older, you do not need to wear a helmet on a standard bicycle, Class 1 Ebike, or Class 2 Ebike.

But you should remember to wear a helmet while riding a Class 3 Ebike, moped, or motorcycle, regardless of your age. An approved helmet has a Department of Transportation (DOT) sticker, ensuring it meets federal safety and quality criteria.

Where Can You Ride An Electric Bike in California?

In California, where you can ride an Ebike depends on its class and local regulations. Let’s see a breakdown under current laws.

Class 1 & 2 Ebikes (max 20 mph):

• Allowed:
  Bike lanes, paths, and trails open to traditional bicycles.
  Roads (follow traffic laws like regular bikes).
  Sidewalks: Only if permitted by local ordinance (check city/county rules).
• Restricted:
  Trails or paths explicitly banning motorized vehicles (e.g., some natural parks or pedestrian-only paths).

Class 3 Ebikes (max 28 mph):

• Allowed:
  Roads and bike lanes adjacent to traffic.
  Bike paths adjacent to roads (unless prohibited by local law).
• Restricted:
  Off-road bike trails, multi-use paths, or protected bike paths not adjacent to roads.
  Sidewalks (unless local law permits).

Can I Modify My Ebike to Increase Its Speed or Power in California?

In California, modifying an Ebike to exceed its legally defined speed or power limits is illegal. Please pay attention to the following class-specific limits.

• Class 1 & 2: Motor must cut off at 20 mph.
• Class 3: Motor must cut off at 28 mph.
• Motor power cannot exceed 750 watts (1 horsepower).

It is prohibited to tamper with the motor, software, or battery to bypass speed or power limits. It will void the bike's classification as a legal Ebike. Modified Ebikes may be classified as motor vehicles, requiring registration, insurance, and a license. Illegal modifications will result in fines for operating a non-compliant Ebike and liability risks in accidents.

Conclusion

You must comply with the rules and specifications for electric bikes when you are in California. Be sure the bikes you order have a maximum motor power of 750W or less. When riding an electric bike, make sure to understand the speed limits. Remember your Ebike's classification and the corresponding regulations during cycling.
