Am I Allowed To Ride My Bicycle On The Sidewalk?

Yes. In California, there is no law that says riding a bicycle on the sidewalk is illegal. The state legislature has left it up to the local counties and cities. For instance, in the city of Sacramento, it's perfectly legal and appropriate to ride your bicycle on the sidewalk. The city has deemed it's safer than riding your bicycle on the street due to distracted driving and congestion. So, in short, there is no law that says you cannot ride your bicycle on the sidewalk.
