Electric bicycle classes, age, helmets, and path access

California defines three e-bike classes up to 750 watts. Class 3 operators must be at least 16 and operators and passengers must wear helmets; bicycle riders under 18 also have a helmet requirement. Class 3 path access is generally limited to paths adjacent to a roadway or locally permitted paths, and local authorities may restrict e-bike operation on paths. 2026 amendments also address Class 3 sales to minors and rear lighting/reflectors.

E-bike speed, trail, helmet, and yielding rules in County parks

In County parks, e-bikes may operate only on park trails and roads where signs specifically allow them. The speed cap is 15 mph; riders under 18 must wear helmets parkwide, and adults must wear helmets on unpaved trails. Riders must yield and give warnings when passing. The ordinance was adopted January 9, 2018; this rule applies only to County facilities, not County streets.
