California e-bike law, cited to primary sources
California sets three e-bike classes in Veh. Code § 312.5. Class 1
is pedal-assist to 20 mph. Class 2 adds a throttle, also capped at 20 mph.
Class 3 is pedal-assist to 28 mph, restricted to riders 16 and older, and
requires a helmet at every age. No class requires a license, registration or insurance
(§ 24016(b)). Everything else — sidewalks, trails, minimum ages below 16 — is set
locally, which is why the answer to "is this legal" depends entirely on where you are standing.

State law: the complete picture
Every California statute governing e-bikes — classes, age, helmets, equipment, where you may ride — with the section number for each rule.
Class 1, 2 and 3 explained
What actually separates the three classes, how to tell which one you own, and what changes legally when you cross a class line.
2026 legislative tracker
Six laws took effect January 2026. Three more were signed September 30 and take effect January 2027. Five died.
Accident statistics
The verified California crash figures, the pediatric injury data — and an honest account of why these numbers are weaker than they look.
Helmet requirements
Two separate helmet rules operate independently — one by age, one by class. Plus the two ways a citation gets dismissed.
Age requirements
One statewide minimum age, applying to one class. Everything below 16 is a county pilot or a city ordinance — and here is exactly where.
Where you may ride
Bike lanes, bike paths, sidewalks, trails and parks — including the widely repeated Class 3 rule that was repealed in 2023.
Fines and penalties
Why a $25 base fine costs $193, when your bike gets impounded, and the diversion programs that make citations disappear.
Find your local rules
State law is the floor, not the whole answer. A Class 2 e-bike that is legal on a Danville street is a violation in a Danville park, and a rider legal in Redondo Beach can be cited a mile north in Manhattan Beach. Two directories cover the gap:
Rules by city
46 jurisdictions compared: sidewalk rules, Class 3 restrictions, minimum ages and fines, each with its code citation.
Rules by trail and park
10 park districts and open space agencies — usually the strictest rules a rider actually meets.
What makes a rule citable here
Every factual claim on this site carries the Vehicle Code section, municipal code section, or numbered ordinance it comes from. Where a rule is documented by a city but its code citation could not be confirmed against an official source, the page says citation unconfirmed and names what is missing. No section numbers are inferred or invented.
That standard costs coverage — several cities here have rules whose citations are still open questions. It is deliberate. A reference that guesses at a code section is worse than one that admits a gap, because a reader cannot tell which claims to trust. The methodology page sets out the sourcing rules and the known gaps in full.
