What Common Mistakes Should You Avoid When Using a Bike Lock?

- Neglecting Regular Maintenance: Over time, bike locks can accumulate dirt or rust, making them less effective. Regularly maintaining your lock, including cleaning and lubricating it, ensures it remains functional and secure.
- Not Using a Locking Mechanism: Some cyclists forget to use the locking mechanism correctly, such as failing to fully engage the lock. Always ensure the lock clicks into place and is secure before leaving your bike unattended.
