The 9 Best Hardened chains (2023 reviews)

This heavy chain will keep honest people honest and probably send bike thieves looking for more easily. It can surly feel all 8 plus lbs. The clearance size and also the weight with a decent padlock is pretty much similar to a high quality u-lock. It comes with that loop of high security it will take any thief a considerable amount of time to steal your trailer.

This is the right size (mass and safety), and the right length chain (to secure the rear tire to the swing arm), hence the optimum chain to carryAs for safety and safety. It can be used on a dual bike carrier loop through 2" receiver safety chain holes. The heavy fabric cover is nice and prevents the chain from scratching surfaces. This chain looks and feels very solid.

Best For Folding Bike: Kryptonite manganese Steel

Buy on Amazon

It is the lightest, most well designed form of a heavy duty "maximum security" chain that kryptonite offers. It's versatile, it's heavy duty, and it's simple. It's also a huge piece of metal that is going to make thieves think twice about trying to steal your bike.

This chain and lock combination leans toward more toward better security and less toward light and easy to carry around. It is great for long commutes to the city. The chain length is long enough to wrap through your frame, front wheel, and bike rack without having to use the Noose. It is much easier to transport on the bike wrapped around the frame and the kryptonite pad-lock is more solid and easier to use than the larger u-lock. The lock has a wonderful noose in the chain allowing you to shorten the length of the chain in use.

Why We Like This:

Very solid, and has a hard-core lock
Best and safest lock for your bicycle
Very strong, heavy noose-style chain and lock

Best Heavy Chain: BIGLUFU Chain Lock

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate chain. The biglufu chain lock is exactly that - it's a simple chain that hits all the right notes. This chain is huge, this will help prevent temptation of theft. It has a plastic feel and loose locking mechanism. The chain lock is wrapped by a water-resistant nylon sleeve, which is scratch-proof and wear-resistant, which protects the chain from scratching your property. The key doesn't really turn smoothly in the lock and can get really annoying opening and locking.

This chain is awesome, super strong. It will keep your bike safe for sure. It is very heavy so only use when you don't have to carry the lock around with you.

Why We Like This:

A great gift to friends, families, or students who needs it
Good investment for long term

Best With padlock: Ram-Pro Hardened Chain

Buy on Amazon

This heavy duty chain is ideal for securing your bike. It measures 1 1/4” across, without getting the calibers out. The fabric cover is quite heavy as well and keeps the chain from rattling. The steel bike chain is perfect to be used for securing the bikes and a number of other possessions which is quite beneficial.

This chain is heavy duty and not light. It is made of premium quality steel, the chains are highly durable in nature and hence are not easily damaged at the time of using them. The tube covering is flimsy and short. The cloth sleeve protects the bike from scratches.

Why We Like This:

Decently thick chain and good quality protractor sleeve
Really thick, well built, nice cover
Good investment for long term

Best With insurance: Onguard Hardened Chain

Buy on Amazon

If you often find yourself confused about appropriate and satisfactory chain, onguard hardened chain should be your first option for buying. This is an amazing chain and lock. The U-lock itself is much more secure and durable than it even looks on the website. It is hefty at 8 lbs with the lock. Even with an angle grinder it'll take a while for anyone to get through this chain. The chain is long enough that it reaches pretty far if you have to park it kind of far away from whatever you're securing it too.

This thing just looks huge and intimidating next to other locks. It is suitable for taking along on bike rides. If you have a moped or motorcycle, this is great.
