Look for locks that are rated at least a 7 or higher on a scale of 10, as these offer superior protection against theft.

Are U-Locks More Secure Than Chain Locks from REI?
When considering the best bike lock from REI, U-locks and chain locks have distinct security features and advantages.
- U-Locks: U-locks, also known as D-locks, are typically made of hardened steel and provide a robust barrier against cutting and leverage attacks.
- Chain Locks: Chain locks consist of a heavy-duty chain and a lock mechanism, offering flexibility in locking options but can be heavier and more cumbersome.
U-locks are highly regarded for their strength and resistance to common theft methods like bolt cutters. Their rigid design allows them to secure the frame and one wheel to a fixed object, minimizing the chance of a thief using leverage to break them. However, their size can be a limitation, especially when trying to lock to larger objects.
On the other hand, chain locks provide a versatile locking solution that can wrap around various shapes and sizes, allowing users to secure multiple parts of the bike or even multiple bikes together. While they can be made of sturdy materials, the thickness and quality of the chain are critical factors in their security level; thinner chains are more susceptible to cutting. Although they may offer more flexibility, they are generally heavier and can be less convenient for transport compared to U-locks.
