California E-Bike Laws and Regulations (2026)

California has one of the largest electric bike markets in the United States and has adopted a three-class e-Bike system designed to regulate different types of electric bicycles according to their speed and power assistance.

Electric bikes are widely used across California for commuting, recreation, and deliveries. As usage has increased, California has introduced additional regulations around rider safety, battery certification standards, helmet requirements, and access to roads, sidewalks, and trails. In general, the state is at the forefront of e-Bike regulations, working faster than most other states to keep up with such rapidly growing ridership and changing e-mobility landscape.

In this article, I summarize the key California regulations and applicable e-Bike laws in a practical and easy-to-understand way, so you can stay compliant and ride safely.

Under California State Law, an e-Bike is an electric bicycle that has fully operable pedals (working bike pedals that propel the bike when turned) and an electric motor with a 750-watt (or lower) motor power limit.

Electric bicycles come in all shapes and sizes, with different power configurations, and so California specifies 3 types of electric bikes based on the top speed that the motor supports (top assisted speed) and whether the motor engages even when not pedaling (throttle assist).

California follows the three-class legal classification system for electric-assisted bicycles:

Also, California specifically bans unlocking e-bikes (tampering so they can exceed their factory official factory settings), and is trying to curb e-Bikes that combine Class 2 and Class 3 capabilities. After SB No.1271 came into effect on January 1 2025, narrowing the definition of Class 3-bikes in California, it's very clear that Class 3 e-Bikes cannot also have a throttle alongside 28 mph pedal assist capabilities.

In California, bikes are generally permitted wherever traditional bicycles are allowed, including roads, bike paths, and many urban cycling routes, unless a sign prohibits it. Access to trails, parks, wilderness areas, and shared-use areas often varies according to e-Bike class, with Class 1 e-Bikes being the most widely accepted and Class 3 being the least.

Brakes

The law states that an electric bike must be equipped with a brake that will enable the operator to make one braked wheel skid on dry, level, clean pavement.

Lights

When out at night, all bicycles must be equipped with:

• A white light on the front (visible from a distance of 300 feet)
• A red rear reflector or red rear light (with built-in reflector), visible from 500 feet when illuminated
• A white or yellow reflector on each pedal shoe or ankle is visible from 200 feet
• A white or yellow reflector on each side forward of the center of the bicycle, and a white or red reflector on each side to the rear of the center of the bicycle, to help make riders visible.
