SizeWhen buying a bike lock, especially a U-lock, it is important to know which size you need. If your bike has a thick frame, you should buy a lock that fits both your bike and the object to which you need to lock it. Keep in mind that a lock shouldn’t be too large, but it should fit perfectly, leaving little space around the bike, so it leaves less room for the thieves’ tools.
ThicknessIt’s probably obvious that if the lock is thicker, it will be more difficult to cut through. However, you should be prepared because the thicker locks are always heavier, and that can make them more difficult to transport. If that’s okay with you, you should choose the thickest lock you can find because it will definitely be more secure.
MaterialOther than the thickness of the lock, another very important feature to keep in mind is the material that it’s made of, especially the chain locks. It needs to be made of really strong and durable steel that is preferably stainless because you have to keep in mind that your bike will probably be exposed to the rain sometimes. High-quality material is more difficult to break, so the thieves will be more likely to give up very quickly.
LengthWhen it comes to cable and chain locks, their length can be important because they need to be wrapped around your bike and the object you’re locking it to. It should be long enough to be usable with the majority of objects but not so long that it will be difficult to transport.
The locking mechanismIt’s not enough to have a very thick and strong chain or cable and a poorly made lock. Choose the bike with a locking mechanism that is high-quality and durable, and that won’t be easy to break. When it comes to a padlock with a numbered passcode, never use a generic code like 00000, or 12345; choose a memorable number that won’t be easy to guess.
PortabilityTry to choose a bike lock that will be easy to carry around, so you don’t get frustrated with it and stop taking it with you. If you have a basket on your bike, you won’t have any problems since the lock can be packed there. If that’s not the case, choose a lock that can be wrapped around the frame or attached to a bracket and transported like that.
