How to choose the best bike cable locks

A cable lock is a basic deterrent, so the right choice depends on what you need to secure and how you plan to carry it. Start with reach. The lock needs enough cable to pass through your frame and wheel and around a rack, pole or fence, so compare the cable length stated in each listing.

Next, look at cable diameter. Manufacturers often describe thicker braided cables as more resistant to cutting, while thinner cables are lighter and more flexible. Weigh that against how much you want to carry, since listed weights in this roundup run from the lightest to the heaviest models shown.

Then decide between keys and a combination. A combination means no keys to carry or lose, but a preset code cannot be changed, while a resettable code can. Key locks need the keys kept safe. Check whether the listing says the combination is resettable and whether it includes keys.

Consider the extras. Mounting brackets help keep the lock off your frame while riding, and vinyl or PVC coatings are listed to help prevent scratches on bikes and gear. Many listings say little about warranties or weather ratings, so if a feature matters to you, read the full listing before you buy.

Finally, follow the manufacturer’s instructions for setting, resetting and testing the lock, since several listings describe specific steps. For general bicycle safety guidance, see the NHTSA bicycle safety resources. If you are also choosing a seat for your ride, see our 29 Best Bike Saddles roundup, and browse more in our Bike Lock Buying Guides or Cycling Buying Guides.

What to look for

  • Cable length that reaches your frame, wheel and the fixed object you are locking to
  • Cable diameter as stated in the listing, with thicker cables generally described as more cut resistant
  • Listed weight, if the lock will ride on your bike every day
  • Combination or key type, and whether the combination is resettable
  • Whether keys are included and how many
  • Mounting bracket, coating and any weather features the listing states

FAQ

Is a cable lock enough to secure a bike on its own?

The listings in this roundup describe cable locks as basic theft deterrents for everyday use. Ask a local bike shop about lock types that suit where you park, and follow the manufacturer’s instructions for using any lock.

What is the difference between a combination and a key cable lock?

A combination lock uses a code you set, so there are no keys to carry. Some listings describe a preset code, while others describe a resettable one. Key locks need the keys kept safe, and several listings include two keys.

Which cable length should I choose?

Measure what you need to reach. Six-foot cables are listed for racks and multi-vehicle lock-ups, while four-foot and shorter models suit a quick lock to a fixed object or a lock that stays mounted on the bike.

Should I follow the manufacturer’s instructions?

Yes. Follow the manufacturer’s manual for setting, resetting and testing the combination or keys, since several listings describe specific steps.
