There are different types of bicycle locks to consider. A U-lock is generally the best bicycle lock for security because it has a limited number of moving parts and can be made of hardened steel. Meanwhile, the chain bicycle lock and cable bike lock offer flexibility. They can be convenient for securing parts, like a removable wheel, to the bike frame. They can also be handy if you need to lock other vehicles, like an e-scooter. However, chains and cables are easier to cut than the bike U-lock.
For the most protection, utilize two bicycle locks at once. First, lock the frame of the bike to a bicycle stand with a U-lock and then lock the bike’s front wheel to the frame and to the stand with a chain or cable bicycle lock.
When you are shopping for a new bike lock, you can also consider bicycle lock warranties. High-end bike locks sometimes include a warranty to cover loss should your bike get stolen when locked correctly.
