How to choose the Best Security Chain

Unfortunately, motorbikes are not so difficult to steal, and most bikers know that they should be mindful to shield their pride and happiness from thieves.

One of the least complex, and best, types of assurance you can get is a bolt cutter proof security chain. A great solid chain will make it significantly harder to move your motorbike, which implies that the amateur thieves will, for the most part, leave it and head out to locate a much simpler target.

Moreover, a great quality bike security chain will make an expert thief’s life considerably more troublesome. On the off chance that they need to break through the chain to move the bike, this backs them off.

This will also make much more noise than they need, all of which will increase their chances of getting trapped and exposed. Realizing how attached most bikers are to their rides; barely any criminals would want to risk being confronted by the motorbike’s owner.

Also, you should chain the bike to something solid, similar to a post or an appropriately secured ground-anchor, generally it’s still moderately simple for criminals to lift the bike into a van with the goal that they can break the chain once they’ve moved to a protected area. If this doesn’t happen for instance on the off chance that you need to stop your bike on a road where there’s nothing to chain it to, the best way to protect your bike will be to wrap the chain through the back wheel and over the seat.

With regards to security, the adage is valid that you get what you pay for. A cheap lock on display at Amazon may look like a great deal. However, chances are that it won’t last too long when a thief comes with the right tools. On the off chance that you truly want to protect your belongings, there are a couple of things you have to search for in a solid security chain:

  • Material : Steel chains

A chain is just as good as its weakest link. The lock itself is one of those links and it would be futile having a thick chain produced out of the worst breakable material just to be held together by a cheap, breakable lock.

The best quality chains, which are strong, are produced using carbon, manganese steel or boron. You should also think about a lock’s strength. If it would be able to survive a hammer’s strike or not or would it be picked or defeated easily. Placing it on the ground is less than ideal as it gives the thief a good solid base to crush it against. Therefore, tight and raised chains work better and are recommended.

A decent quality, heavy security chain also works the best for covering your lovely bike with imprints, scratches and minor breakages. Search for one with a defensive cover, for example, nylon.

By no means should you compromise and get a security chain that isn’t made of steel. Search for a base thickness of 10mm for ideal strength. Thicker chains are far and away superior, so it’s ideal on the off chance that you can discover something 11mm or thicker.

  • Link structure

Circular links are moderately simple to break, so you’ll need to search for chains that are square molded or hexagonal. Of the two, hexagonal are essentially more grounded than square molded links.

  • U-lock

You can’t beat the trustworthiness of a U-lock. Search for a security chain that connects the loop with a U-lock for extreme insurance.

  • Nylon cover

A nylon cover doesn’t help a lot with security, yet you’ll need it to shield your bike from getting scratched by the steel chain links.

  • Length of the chain

There are some extra benefits with a chain that is long enough, for example, far and extended reach and double wrapping. A long chain is heavier but that won’t cause an issue in case you’re ready to stow it securely when you’re out.

The chains can be kept protected under seats if large enough. Looping it around your chest area when riding can interrupt your movement and cause additional wounds especially when you are in a difficult situation.

Picking the proper level of security

“Opportunity Thieves” are unorganized opportunists who see a simple opportunity to profit on poorly locked bikes of all, steal most of the bikes. Weapons of such criminals are usually bolt cutters. Other tools used for the same purpose are hammers, simple saws or sometimes just their hands.

You wouldn’t believe what number of bikes can be simply squirmed free or carried away. In any case, when you pick a better than average lock (and lock the bike appropriately), bolt cutters will fail to defeat the lock.

Always aim for a lock somewhere above 13mm as they prove to very hard and are not easily defeated by bolt cutters. Further, you can also choose for a 15mm locks as cut defeat them thieves would need a pro tool which will attract attention.

Frequently Asked Questions [FAQ’s]

Here are some frequently asked questions:

Q: Which size chain cannot be cut with bolt cutters?

Q: Is there any security chain that cannot be cut?

To stop the thief, you need another plan.  As all that any chain is going to do is stop the thief and slow down the process of stealing.

Q: What does “through hardened” mean?

Case hardening affects just the shell or “skin” of the chain. A thief can file through the case hardened part of the skin and after that use bolt cutters in the file cut –  it’s just soft steel under that and it’s a simple task to finish off the job.  You can’t do that with thru hardened chain.
