Vehicles: electric bicycles.

Assembly Member 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 prohibitions against selling physical products or devices that alter electric bicycle speeds beyond their designated class limitations - 20 mph for Class 1 and 2 bikes, and 28 mph for Class 3 bikes.

The bill maintains current requirements that electric bicycle manufacturers certify compliance with U.S. Consumer Product Safety Commission standards while adding specifications for motor operation. Motors must disengage when brakes are applied or include a mechanism that can deactivate the motor. The legislation also reaffirms that electric bicycle operators are exempt from requirements for financial responsibility, driver's licenses, registration and license plates that apply to motor vehicles.

Under the measure's provisions, modifications to electric bicycle speed capabilities remain permissible only if the vehicle continues to meet its class definition and displays updated classification labeling. Violations of the expanded prohibitions constitute infractions under the Vehicle Code, with enforcement costs borne by local agencies without state reimbursement.
