Kryptonite New York Fahgettaboudit 1415 (999492)

The Most Secure

Kryptonite is a world-known company that produces high-quality security products for bicycles, motorcycles, snowmobiles, and other vehicles. No wonder bike locks by Kryptonite are considered the most secure and reliable on the market today. The very name of the lock - Fahgettaboudit - literally means that no thief will be able to damage or steal this lock, the hardened manganese steel chain links are totally uncuttable.

To keep the lock look nice longer, the manufacturer paired it with a nylon cover to protect it from mechanical damage. So, if you don't want your lock to be scratched, make sure to use it every time.

The kit includes three keys, one of which is lighted for comfortable use of the lock during nighttime. If needed, you can order more locks with a special program offered by Kryptonite. There are two options available - 5-inch and 3.25-inch locks, so you can choose the one that fits your bike best.

Admittedly, Kryptonite bike locks aren't the most portable locks on the market. With the weight of 10.8 lbs and 14 mm links, carrying them in your pocket won't be an option. Yet, they are not about portability. What they are designed for is providing security and that's where they definitely shine.

What customers say about this product

Key Specs

This lock is a beast! Even the lock is a beast! My girlfriend has had 4 bikes stolen so this was my last resort! It looks like this may be a solution to the problem.

Features

The chain is just long enough to loop it through parts on my bike. The cloth cover is nice, but a little scratchy, so be careful when pulling the chain through any expensive painted bodywork.
 

Kryptonite Kryptolok Standard w/4-foot Flex Cable

Just Register It!

As mentioned, Kryptonite is a big name in the industry of security accessories for bikes. Kryptonite stands behind product quality and service, so you can be sure you're getting one of the sturdiest locks on the market. And to understand how reliable the lock is, just consider the fact that Kryptonite will pay you out certain value in case it's somehow defeated. The only requirement from the manufacturer is to register your product online.

Another perk you get upon registration is the free delivery of spare keys in case of loss. It's worth emphasizing that the "Key safe" program covers only the first keys included in the package. By the way, the lock comes with 2 keys that have an ergonomic design to reduce the amount of torque and prevent the breakage.

The box also includes the patented Flexframe-U mounting bracket. It's fairly versatile and can be mounted on any part of the frame, providing a hassle-free fitting and convenient location of the lock. The D-lock itself is supplied nicely wrapped into a dustcover.

Review of Kryptonite Kryptolok Standard w/4-foot Flex Cable

Gold Rated

The Kryptolok is a heavy-duty shackle bike lock with the added protection of a 4-foot double-loop chain. But the cable, in our opinion, is a bit too short to go through the bike frame, wheel, and rack. For that extra security, a longer cable is required. Still, the braided steel cable can secure a front wheel or the rear triangle of the frame. And since it's wrapped in a protective vinyl coating, it won't scratch anything.

The D-lock itself appears to be pretty indestructible. It's made with 12.7mm hardened performance steel shackle and boasts the patented “Pass-Thru” design. This new design offers enhanced protection against cut and twist attacks. Meanwhile, a high-security disc-style cylinder offers even more protection with its pick and drill resistant properties.

What is notable, the core boasts a special protective mechanism that prevents dirt and dust from getting inside. This not only prolongs the life of the lock but also minimizes the risk of a key sticking inside.

To conclude, it's a Sold Secure certified lock that is gold rated. Gold-rated locks are proved to “offer the highest level of security”, so you can be sure you're getting an effective bike lock suitable for use in high-theft areas.

Via Velo 14mm Cable with Mounting Bracket

Reasonable Choice

In case you're looking for a reliable heavy-duty lock but don't want to shell out much money on big names, you may be interested in this model provided by the Via Velo company. It's a moderately-priced bike lock that can give more expensive models a run for their money. Actually, it comes as close to famous Kryptonite locks in terms of protection as possible.

To begin with, we would like to note that this lock boasts the thick 0.55-inch drill-resistant shackle that is made from ultra-durable heat-hardened steel. Given the fact that the cutting force strength of this material makes 34.3 kN, the lock can stand up to cutting, jacking, leveraging, and prying attacks. The pulling force strength makes 29.3 kN.

We would like to stress that the double-bolt mechanism secures the shackle on the crossbar in two places, which makes the lock nearly bombproof. As for the chain, the lock comes with a 5'10" woven steel cable that is long enough to secure both wheels and some accessories. And since the cable is covered in smoke-grey transparent PVC coating, it will neither scratch the surface of your bike nor let the moisture in. It effectively resists corrosion, dust, and dirt.

Review of Via Velo 14mm Cable with Mounting Bracket Heavy Duty Bicycle U-Lock

For Medium and High-Theft Areas

For easy storage, the Via Velo lock comes with a convenient mounting bracket that can be attached to a bike frame. The said mount rotates 360 degrees, allowing cyclists to fit the lock in the frame or alongside it.

What we also like about this heavy-duty lock is the generous package - the manufacturer supplies it with as many as three safety keys, making it possible for you and your spouse to use the same bike without a need to constantly pass a key to each other. With a spare one.

Take note that the keys can't be copied. However, if you somehow lose them, you can order a replacement through the Via Velo's Key Guard Program. You should simply register your unique code online after purchase.

All things considered, we can highly recommend this moderately-priced lock to all cyclists living in a medium or high-crime area. The manufacturer hasn't cut corners and made it extremely durable and suitable for maximum protection. A great alternative to higher-end models.

OTTOLOCK Steel & Kevlar

Ultra Lightweight

In case you're looking for something ultralight to carry in your pocket or saddlebag rather than on special mounting brackets, we have included the OTTOLOCK Steel & Kevlar Combination Bike Lock in our list.

The lock is designed especially for those cyclists and outdoor enthusiasts that tend to travel light and need a super compact, lightweight solution for quick in and out stops.

The cable has a multi-layer rugged construction with the combo of stainless steel and Kevlar inside and anti-scratch Santoprene plastic outside. But frankly speaking, the cable isn't supposed to stand up to professional devices that thieves usually use. A bolt cutter is able to cut it off in approximately five minutes, so we wouldn't recommend using the lock for securing your bike overnight somewhere.

The OTTOLOCK lock is good for short-stay security against theft opportunists. It's a good option for locking up your bicycle while you're exercising at the gym or grabbing lunch in a low-risk area, for example.

Review of OTTOLOCK Steel & Kevlar Combination Bike Lock

Variable Options

This simple digit lock is available in several length options to suit most travel needs. Naturally, the weight varies with each modification, starting at 0.4 lbs for the shortest 18-inch cable.

The shortest 18-inch model offers somehow limited reach and is best for weight-minded users. It can tie single bike tubes to posts. If the object isn't too big, it should fit nice and snug. This type fits easily into a jersey pocket.

The 30-inch lock is the most versatile length. It offers virtually the same amount of portability with little-to-no weight trade-off. The medium-size lock will easily fit inside of a small backpack or your pocket if you roll the lock up. Yet, it's long enough to secure a frame and wheel to an outdoor bike rack.

The largest, 60-inch lock is the best option for securing multiple bikes and car/truck racks.

Each of these options can also find many other outdoor uses. For instance, you can secure camping gear, canoes, coolers, construction tools, and similar stuff using the OTTOLOCK. It provides good short-stay security for just everything you can tie around.

Titanker 4-Feet

Light and Versatile

Need an affordable backup lock for your property? If so, you should seriously consider the Titanker Bike Lock. For nearly $10, you can get a decent cable with a reliable 4-digit combination locking mechanism.

The cable is made of high-quality steel and covered with PVC coating that prevents any possible scratches on your vehicle and makes the lock a bit more durable. However, it's important to point out that it isn't as thick as the one used on higher-end models and less strong too, though it doesn't stop it from protecting your bike. Besides, a bike with a lock is still way safer than a bike without one.

Further on, thinner cables mean lighter weight. The Titanker Bike Lock isn't as hefty as other locks on the list, which makes it suitable for use not only on bicycles and other types of vehicles but sports equipment, gates, fences, BBQs, lawnmowers, tools, storage sheds, ladders, and similar items as well.

Finally, the lock is very easy to install. The package includes a mounting bracket that attaches to your bike seat post or frame post. It uses an easy-to-release attachment mechanism, letting you hook the cable neatly when it is not in use.
Review of Titanker 4-Feet Bike Lock Cable

How to Set Your Code

This multipurpose 4-digit lock allows for 10,000 combinations, which makes it nearly impossible to crack. However, the complicated mechanism is fairly easy to set up for users.

The lock is originally pre-set to 0000. In order to select your own digit combination, you should follow these simple instructions:

  1. Set the combination wheels to 0000. The default code must be aligned to the line with two bumps.
  2. Rotate the set/reset knob, keeping the default password. Open the lock.
  3. Turn the dial wheels to your preferred combination, making sure that all the numbers match the pointer.
  4. As soon as you set your personal digital combination, turn the knob back to its original position (90 degrees left). You're done. The new combination is chosen.

To sum it all up, if you need a lightweight and easy-to-use combination lock, this one can be a good choice. Though a bit thinner than some other locks we've reviewed here, it is strong enough to ensure the needed level of  protection to your bike, ATV, or anything else that you want to secure.

What Is a Bike Lock?

Safety comes first, especially when it comes to the protection of your vehicles. A mind-boggling fact is that more than 1.5 million bicycles are stolen each year. And the best precaution against theft is buying a reliable bike lock. Today, bike locks come in a wide variety of styles and shapes. To understand which one will suit your bike it is important to measure your bike and check what installation options are available. If you see that it's enough to secure only one wheel with a frame, you can safely opt for a simple U-lock. In case you seek a bit longer reach, though, we recommend you consider a lock with a chain.

For this review, we have rounded up the strongest locks that can cater to any need and type of bike. They have undergone expert testing and have been proven to be very effective and secure. So, by choosing one, you can have peace of mind knowing that your two-wheeler is well-protected while you're away.

In addition, we recommend you to consider top-quality bike pumps for a comfortable and hassle-free ride.

What Features to Compare

Type

Today the market offers a great number of bicycle locks with different protection levels. So, to choose the right lock, you need to decide what level of protection you actually need.

  • U-Locks are the most secure and theft-proof locks on the market. They are made of uncuttable materials and are very convenient to use. U-Locks come in various sizes, yet, you should choose the rigid one that will sit tightly on your frame. U-locks are perfect for high-risk areas.
  • Chain Locks are also considered to be super secure anti-theft equipment. No wonder, they are recommended for use in areas with high crime rates. However, their reliability often depends on the type of steel, the thickness, and the overall lock quality.
  • Cable Locks are a more versatile option, but not the most reliable. Yes, they are fairly lightweight, compact enough, easy-to-use, also they might be cheap, though, they offer very little security. Thus, for greater reliability, they are often combined with U-Locks. Generally, cable locks are recommended for use in low-risk areas.
  • Folding Locks consist of linked metal plates. Hence, they can be folded compact for transportation. Also, they are not heavy, and like U-locks, they offer a great level of security. Plus, they are pretty flexible, which means that you'll get more options on how to lock your bike.
  • Wheel Cuffs Locks. Such locks resemble cuffs, one end of which should be fixed to the frame, while the other fixed to the rim, thus blocking the movement of the bicycle. However, the wheel lock does not prevent thieves from carrying a bike in their hands, so this type of lock is not recommended as the only secure lock.
  • Locking skewers for Seats. They work in a great number of ways. For example, some of them use non-standard keys, while others can use gravity to lock the levers.

All of the mentioned locks are most common, however, nowadays you can find locks that do not fit into any category. In addition, the locks may have a key or code mechanism. Here the choice depends on your taste, whether you prefer using a key or a code combination.

Material and Set

As it was mentioned above, bicycle safety depends on the material. Make sure that the lock has been manufactured from high-quality steel. It will be much more difficult for thieves to cut strong and thick steel.

Also, pay attention to the set. It will be great if a lock comes with a few keys and protective pouch.

Weight

As a rule, the weight is often directly proportional to the reliability. We mean that a strong thick steel lock can weigh quite a lot but boasts a great level of protection. Therefore, you need to decide whether you need a light portable (< 12 mm) lock or heavier and more reliable one (> 12 mm).
