On July 2, 2024, California Governor approved Assembly Bill 1774, ushering in significant changes to the regulation of electric bicycles (e-bikes) in the state.

Overview of AB 1774

California has introduced AB 1774 to impose stricter controls on electric bicycles. This new legislation outlaws unauthorized modifications that increase the speed of e-bikes and prohibits the sale of products intended for such alterations. Violations will be treated as criminal offenses and enforced by state and local authorities. Local governments will not receive state reimbursement for expenses incurred due to the new regulations. These measures aim to enhance road safety and ensure e-bike compliance.

Key Changes Introduced by AB 1774

The new law modifies Section 24016 of the California Vehicle Code, implementing more rigorous regulations for e-bikes. Here’s a summary of the main changes:

Prohibition of Illegal Modifications

The law now explicitly bans any alterations that increase an e-bike's speed unless the e-bike retains its original classification and appropriate labeling. This ensures that e-bikes remain within legally defined safety and performance standards.

How will authorities ensure compliance with this new rule? Effective enforcement strategies and public awareness campaigns will be essential.

Ban on the Sale of Speed-Altering Products

AB 1774 also prohibits the sale of devices that can modify an e-bike’s speed capabilities, making it non-compliant with legal standards. With many such products available online, the state faces challenges in preventing these sales. Monitoring online marketplaces will be crucial to enforcing this ban.

Enforcement and Local Program Implementation

Violations will be criminal offenses, requiring enforcement by state and local authorities. Resources must be allocated to ensure compliance and enforcement. The law calls for a state-mandated local program, but specific implementation details are pending.

Legislative Background

Assemblymember Dixon introduced AB 1774 in response to growing concerns about e-bike safety and regulation. Existing laws define e-bikes as bicycles with operable pedals and an electric motor of less than 750 watts. The new bill clarifies and strengthens these regulations to prevent misuse and enhance safety.

What measures will ensure manufacturers comply with the new standards? Compliance checks and certification processes will be necessary to uphold safety regulations.

Financial and Local Government Impact

While AB 1774 introduces new restrictions and enforcement responsibilities, it does not mandate state reimbursement to local governments for related costs. This exclusion stems from the California Constitution, which exempts costs associated with enforcing new criminal offenses from state reimbursement. How will local governments manage the financial burden without state assistance? Effective budgeting and resource allocation will be essential.

Voting and Implementation

The bill was passed with a majority vote, reviewed by the fiscal committee, and does not involve appropriations. The implementation of this law aims to ensure safer roads and better-regulated e-bike use across California.

What is the timeline for full implementation of AB 1774? Knowing this will help e-bike owners and manufacturers prepare for compliance.


The passage of AB 1774 marks a proactive effort by California legislators to address the evolving use of e-bikes. By preventing unsafe modifications and regulating the sale of related products, the state aims to ensure that e-bikes remain safe and reliable.

As these new regulations take effect, e-bike owners and manufacturers must stay informed and compliant with updated legal standards to avoid penalties and contribute to safer roadways.
