How California Electric Bicycle Laws Work
California electric bicycle laws sort ebikes into three classes based on top assisted speed and whether a throttle can power the bike alone. Every class needs working pedals and a motor of 750 watts or less. Riders follow ordinary bicycle rules.
Class 3 bikes carry extra limits on age and helmets. So the label on the frame, and the bike’s real capability, decide which rules apply.
The Three Classes
Vehicle Code section 312.5 defines the classes. The CHP bulletin on electric bicycles summarizes them this way.
- Class 1 gives pedal assistance only and stops helping at 20 miles per hour.
- A Class 2 bike can run on throttle alone and cannot provide assistance at 20 miles per hour.
- Class 3 gives pedal assistance only, stops at 28 miles per hour and has a speedometer.
In addition, Class 1 and Class 3 bikes may have a walk mode that moves the bike on motor power up to 3.7 miles per hour.
What Is Not an Ebike
Some devices look like ebikes but fall outside the definition. According to the CHP, a two or three wheeled device that the maker intends to be modifiable beyond 20 miles per hour on motor power alone does not qualify. Neither does one with more than 750 watts.
A bike modified in those ways, or with its pedals removed, also loses ebike status. Such a vehicle may count as a moped, a motorcycle or an off-highway electric motorcycle instead. The CHP notes that off-highway electric motorcycles, a category added in 2026, may not ride on public roads.
Before buying, compare the motor rating, top speed and pedals with the definitions. A seller’s description alone may not match the legal category.
Age Rules in California Electric Bicycle Laws
Section 21213 bars anyone under 16 from operating a Class 3 ebike. Class 1 and Class 2 bikes carry no such statewide age floor in the CHP summary. Still, local rules and parents may set stricter limits. Police may impound a Class 3 bike ridden by someone under 16, according to the CHP.
Helmet Requirements
Section 21213(b) requires helmets for all Class 3 operators and passengers, regardless of age. For Class 1 and Class 2, the general bicycle rule applies, which requires helmets for riders under 18 on public roads and bikeways. For full details, see California helmet laws.
No License or Registration Needed
Under section 24016(b), an ebike is not a motor vehicle. Riders need no insurance, driver license, registration or plates. However, that freedom applies only to true ebikes that meet the definition. Once a device falls outside it, the rules for motor vehicles may apply.
Equipment in California Electric Bicycle Laws
Section 24016(a) requires ebikes to meet federal bicycle safety standards. The motor must stop when the rider brakes or releases a switch. Section 21201(f) requires a red rear reflector or red light with a built-in reflector visible from 500 feet at all hours. So check lights and reflectors before every ride.
Modifications Under California Electric Bicycle Laws
The law bars changing an ebike’s speed capability unless the owner replaces the label to show the new class and the bike still meets the ebike definition. Selling devices that push an ebike beyond the definition is also illegal under section 24016(e). So avoid speed kits and unlocked controllers. A modified bike may lose its ebike status entirely.
Where Each Class May Ride
The CHP describes ebikes as generally allowed wherever bicycles may ride.
Section 21207.5 itself sets out exceptions. A local agency may ban ebikes, or certain classes, on equestrian, hiking or recreational trails by ordinance. State Parks may also ban ebikes or certain classes on paths and trails it manages. So local path rules can differ from one trail to the next.
Statewide Rules Versus Local Rules
State law sets the baseline. Cities, counties and park agencies may add limits on certain trails, as allowed by law. Therefore, look for posted signs at trailheads and check the managing agency’s website before riding. Proposals to change ebike laws also appear from time to time, yet only enacted rules carry legal force.
Passengers
Carrying a passenger raises safety and design questions. For example, some ebikes have seats built for a second rider, while others do not. Therefore, follow the maker’s limits. On a Class 3 bike, every passenger must wear a helmet under section 21213(b).
Training Resources
The CHP offers online ebike safety training, created after a 2022 state law. It covers riding skills, emergency maneuvers and rules of the road. Parents of teen riders may find it useful, especially before a first bike purchase. For broader rules for vehicles like mopeds and motorcycles, see the CHP vehicle guide.
Shared Road Duties
Section 21200 gives bicycle riders the rights and duties of drivers, and ebike riders follow those rules. As a result, ebike riders must obey signals, signs and lane rules. Also, they must yield where any bicycle rider would yield. For proof steps after a crash, see Sacramento bicycle accident evidence.
