Can you tell me what bike locks offer the best protection against theft?
<|assistant|>
The best bike locks for theft protection are those that are heavy-duty and use complex locking mechanisms. U-locks, which provide a protective metal cable between the two loops, and disk locks, which have a solid steel disc inserted into a bracket, are the most secure and resistant to being broken into.
