While most of the parking is substandard, there are some good racks out there. These racks are also downtown. What I like about them is that they are minimalist, space efficient, and support your bicycle while allowing it to be locked securely.
A word of caution. Bike theft is on the rise. If something isn't secured by a lock - you are running the risk of it getting taken. Especially with the economy in a funk, people are looking to make an easy dollar anyway they can. Don't let your bike be a part of that cycle.
Also - don't compromise and park at a crappy rack where your bike isn't secure. Ride around and find a light post, parking meter, bench, or something secure that will keep your bike safe.
If you know of any additional places in Culver City or Los Angeles that have substandard bicycle racks, shoot me an email here.
