• Cable Locks: Cable locks are flexible and lightweight, making them easy to carry and maneuver. While they provide basic security, they are generally more vulnerable to cutting, so they are best used in low-risk areas or in conjunction with a more secure lock.
• Chain Locks: Chain locks consist of a chain with a padlock or a built-in locking mechanism, offering good flexibility and the ability to secure multiple bikes or accessories. The strength of a chain lock can vary significantly based on the thickness and material of the chain, so choosing a high-quality option is crucial.
• Folding Locks: Folding locks are made up of several linked segments that can fold into a compact shape for easy transport. They offer a balance between portability and security, combining the flexibility of a cable lock with the sturdiness of a U-lock.

• Invest in a Quality Lock: Choose a sturdy lock that offers reliable security features, such as a U-lock or a heavy-duty chain lock. The best bike lock under 20 can still provide substantial protection, but ensure it has good ratings against theft.
• Lock Your Frame and Wheels: Always lock both your bike frame and at least one wheel to a solid, immovable object. This prevents thieves from simply rolling your bike away or stealing the wheels.
