No horns/bells: Seems to refer to L.B.M.C. section 10.48.080: ???No person shall operate a bicycle upon a sidewalk unless it is equipped with a bell, horn or other device capable of giving a signal audible for a distance of at least one hundred feet, except that a bicycle shall not be equipped with, nor shall any person use upon a bicycle, any siren or whistle.??? But this applies only on sidewalk
