best lightweight bike lock

Kryptonite New York is made of 18mm hardened maximum performance steel. Therefore, it provides incredible resistance against all kinds of cutting tools including saws, grinders, bolt cutters, and other hand tools.

The lock also boasts a “pass-thru” crossbar design, just like other U-locks by Kryptonite. It has been designed to foil all types of theft attempts, especially cutting, drilling, and sawing attacks. A thieve has to cut the lock twice to steal your bike which is like a suicide in public places such as university parking lots, parks, markets, and others.

Kryptonite New York also has a very unique design. Instead of passing through the bottle boxes, the lock attaches to the frame thanks to the nylon strap that comes with the mounting bracket.

Some people, however, call the durability of the lock in question just because it relies on friction to stay in place.

Our Verdict

Kryptonite New York Fahgettaboudit is a great bike lock with the most reliable security features. It promises to protect your bike from thefts and keeps its promises 99% of the time. You must go for this lock if you want supreme protection and uncompromising security for your bicycle.

  • Lightweight and sturdy
  • Uncompromised protection
  • Unique design
  • Easy to use
  • Free online theft-protection
  • Rated 10/10 on Krypton’ security scale

best lightweight bike lock

Kryptonite is a renowned and reliable name when it comes to making highly secure bike locks. A kryptonite bike lock will always keep thieves away despite its specifications and secure ratings and 1275 Chain Lock is no different.


Chain locks offer many benefits which other types of locks cannot. First and foremost, you can attach them around almost anything because of their flexibility. Secondly, most chain locks are made of hardened steel and may live longer even than your bike. Thirdly, they are incredibly hard to cut due to their links which shift and move around. Even an angle grinder will fail to cut through them.

When you combine all of the above features, you get Kryptonite New York Noose 1275 Chain Lock. It is unbelievably robust as each link in the lock is made of hex-style 3t hardened manganese steel. The reinforced steel provides extra strength. You simply cannot cut it with an angle grinder, nothing to talk about a bolt cutter or a hacksaw.

Other impressive aspects of the lock are the durability and size of the chains. You will fasten the lock with a small kryptonite 14mm MAX-PERFORMANCE STEEL shackle having a complex, four-cylinder design. Similarly, it is also reinforced just like the chains.

A nylon fabric material further covers the steel and protect both the chain links and bicycle frame from scratches as well as dust.

The lock weighs comparatively more than its major rival which is its only drawback. You must also oil it regularly because it tends to get sticky in wet conditions.

The most interesting part of having Krypton Noose 1275 is that you can also activate optional Anti-Theft Protection. All you need to do is to register your product online. Kryptonite will pay you a part of the overall security value of your product in case the lock fails to protect your bicycle from theft.

Our Verdict

Kryptonite New York Noose 1275 is an excellent bike lock. It is perhaps the best lightweight bike lock for its extra-hard steel chain links and shackle as well as strong, secure features.

  • Easy to fasten

Types of Lightweight Bike Locks

You need more security and thus high-quality locks that are impossible to beat in high-risk areas including universities, parking lots, and major metro areas. There are four different types of bike locks and here is how each one of them differs from others.


U-locks are the heaviest and most expensive of all the bicycle locks. Therefore, an imprudent thief at least needs a power tool to cut them. Hand tools such as saws and hacksaws stand no chances against U-Locks. Made of hardened steel, they offer unbelievable strength against thefts. A thief would need two cuts to open the lock in case of high-end U-locks that feature double deadbolts such as Kryptonite New York Fahgettaboudit U-Lock.

Folding Locks

Folding locks in the likes of ABUS Gordo Granit X-Plus are very popular among commuters for their small size and compact design. They also become a terrific alternative to cable and chain locks. However, they are not as robust as U-Locks. Thieves can drill a hole through their connecting joints using a power drill. Similarly, they are vulnerable to bolt cutters as well. However, they are an ideal option for objects that are too big for U-locks.

Chain Locks 

You can use chain locks instead of U-Locks as long as the chain is made of hardened steel. Not to mention, the shackle has to be equally durable as well. The biggest benefit of a chain lock is that you can fasten it around both wheels as well as poles and trees irrespective of their diameter. Some of the models are very portable as they fit securely around your waist.

Lightweight Locks

Lightweight locks incorporate all other types of locks. These locks are available in a wide variety of materials and designs such as OTTOLOCK Steel and Kevlar Cinch Lock. Lightweight locks tend to be very cheap but an easy target for thieves. Even the hand tools like tin snips and bolt cutters can defeat them. Therefore, they are ideal only for securing your bike for short periods such as drink breaks or popping into a store.

Bike Locks Security Ratings

Many different companies have a security rating system for locks. However, Sold Secure is the most reputable and reliable of all the companies or ratings. Founded by Master Locksmiths, the company facilitates the users to compare the quality of different locks and safety products.

Sold Secure awards one of three ratings to the best lightweight bike lock that meets their testing criteria. These ratings are Sold Secure Bronze, Sold Secure Silver, and Sold Secure Gold.

As you can imagine, locks with the Sold Secure Bronze rating are the weakest of all locks and cannot stop professional thieves to steal your bike. They can serve as a theft deterrent at best and nothing else. They only keep opportunist thieves at bay and thus, they are a big waste of money. You must avoid them at any cost and that is why we haven’t included any lock with Bronze rating on our list.

Locks with Sold Secure Silver Secure ratings are comparatively better than the ones with Bronze Secure rating. They offer a sort of compromise between price and security. Most lightweight bicycle locks have Gold Secure Silver rating. They are suitable for short-term use or cheaper bikes.

Gold Secure Gold rating is the highest and the best rating a bicycle lock can have. These locks provide your bicycle with maximum and uncompromised security. Locks such as Kryptonite New York have Sold Secure Gold Secure Gold rating.

How to Buy the Best Lightweight Bike Lock.

Apart from type and security rating, you need to consider many other things while buying a lock for your bicycle. The following is a summary of each of these factors.


Bicycle locks made of hardened steel or titanium are the best. Such locks tend to be expensive and not everyone can afford them. However, they are impervious to bolt cutters, hacksaws, and other hand tools, much to the dismay and fright of bike thieves.

There are also locks made of cheaper softer allows that can easily be defeated by hacksaws, bolt cutters, and sawzalls.


We have already covered this point to some extent in the material section. The whole idea behind having a bike lock is to secure your bicycle. Therefore, you must go for a lock that offers maximum security to your bike. In our experience, only U-locks made of hardened will successfully thwart any theft attempt 100% of the time.


Many people ignore practicality while buying the so-called best lightweight bike lock. For example, you should not buy a massive chain lock if you commute to work because it is difficult to carry in your bag. Practicality also encompasses size and design which should play a vital role in making the final decision.


You should spend as less money as possible on a bike lock. However, it does not mean you should settle on a substandard lock. Many locks offer you the highest quality, maximum security, and extreme durability for a very reasonable price such as all the locks on our lists.

Final Thoughts

It is pertinent to mention that no lock in the world is invincible. A determined thief can go through the defences of even the most robust of locks. However, the best lightweight bike lock will make your bike securer than ever before. You will have peace of mind that no one can dare touch your bike, nothing to talk about stealing it. Similarly, people with evil intentions will think a thousand times before trying to pick your bike.
