Vehicles: electric bicycles.

Assemblymember Davies' legislation expands California's electric bicycle safety regulations by prohibiting the sale of applications that can modify these vehicles' speed capabilities. The measure builds upon existing law, which already bars the sale of physical devices that could alter electric bicycles to exceed their defined speed limitations - 20 mph for Class 1 and 2 bikes, and 28 mph for Class 3 bikes.

The bill maintains current requirements for electric bicycles, including compliance with U.S. Consumer Product Safety Commission manufacturing standards and automatic motor disengagement when brakes are applied. Electric bicycle operators remain exempt from vehicle registration, licensing, and financial responsibility requirements, as these devices are not classified as motor vehicles under state law.

Local agencies will enforce these new provisions as infractions under the Vehicle Code, with no state reimbursement required for implementation costs. The measure preserves manufacturers' obligations to certify compliance with federal safety standards while adding this new prohibition on speed-modification applications to the existing framework of consumer protections.
