How to Lock Your Bike
Proper locking is the first defense against bike theft. In San Francisco, always use a hardened-steel U-Lock as your primary lock. Cable locks and cheap U-Locks can easily be cut. Secure your wheels with locking skewers (best) or cable around both wheels. Lock the U-Lock to the bike frame (never just the wheels) and to a secure rack or pole. Allow for as little space within the lock as possible; loose locks can be more easily broken open.
