It’s official – If you ever ride your bicycle on the sidewalk, you need a bell!
Where this law can be found is still beyond me, as I have yet to locate it myself. Thanks to an anonymous comment we now know that any bicycle ridden on the sidewalk is required to have a bell or other signal device.
LBMC 10.48.080 Signaling device required.
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. (Ord. C-6322 § 2, 1986)
Other Long Beach laws you should be aware of:
~Cars are the only items allowed in a garage.
~It is illegal to curse on a mini-golf course.



So a vocal warning is not enough? Aren’t you glad your city fathers are focusing on important issues!

In Switzerland, every bicycle has a bell (and a dynamo to generate energy for lights); it’s almost impossible to buy one without a bell.
