Existing law, the California Bicycle Transportation Act, establishes 4 classifications of facilities, referred to as bikeways, that provide primarily for, and promote, bicycle travel. Existing law requires a person operating a bicycle, which includes an electric bicycle, upon a highway to ride the bicycle upon or astride a permanent and regular seat unless the bicycle was designed by the manufacturer to be ridden without a seat. Existing law requires a person riding as a passenger on a bicycle upon a highway to be upon or astride a seat attached to the bicycle, as specified. A violation of these provisions in punishable as an infraction. This bill would make those provisions applicable to the operation of a bicycle upon a Class I bikeway. By expanding an existing infraction, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
