Can you tell me what bike locks offer the best protection against theft?
<|assistant|>
The best bike locks to protect against theft are high-security chain locks, U-locks and disc locks. These locks have more complex lock mechanisms that make them hard topick and drill, making them the best defences against bike theft.  Additionally, using a lock with a high quality steel housing can provide extra protection.
