What is a Bike Lock

A mind-boggling fact is that more than 1.5 million bicycles are stolen each year. The best precaution against a theft is to buy a reliable bike lock. So, if you’re hunting for a good quality bike lock, we suggest you look through our review of the strongest locks!
In addition, we recommend you to consider bike pumps for a comfortable 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 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, the 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).

Abus 6500

Compact Defender

In general, folding locks are not considered to be the most reliable. But that doesn't go for the locks produced by Abus company which is actually the inventor of this innovative protection system. The Bordo locks series is known for their unique design no one has used before. Being constructed of six linked steel bars, the ABUS Granit Bordo X-Plus combines the reliability of U-locks and convenience of chain locks.
First of all, this top-of-the-line lock is really compact, sturdy, lightweight, and flexible. You can either wrap it around the seat tube with non-slip velcro straps or screw the case into braze-ons meant for a water bottle holder. To make this folding bike lock as reliable as possible, the plates are made of hardened steel and the links are based on ABUS Link Protection Shield technology which provides additional protection against drilling. The cylinder lock, by the way, also ensures the highest level of security against manipulation. On top of that, we can add that the steel plates are coated with a two-component polymer coating which prevents possible damage to the bicycle paintwork.
The bonus? The Abus bike lock comes with a convenient bag for transportation and two keys, one of which is LED-lighted. Thanks to the cards with the unique lock code, you can always order replacement keys in case the originals have been lost. Don't think twice, get the ABUS Granit Bordo X-Plus.
Review of Abus 6500

Interesting to Know

Chilean engineers claim they have found an effective way against bike theft. They created Yerka, the world's first "unstealable" bicycle. Outwardly, it looks like an ordinary bike, yet it has a special frame with an integrated bike lock, which allows users to fasten the bicycle to a pole or a tree wherever and whenever they want. The transformation of the frame takes 10 just seconds! Plus, the wheels of Yerka are equipped with special anti-theft nuts which can be unscrewed only with a special key. So, nobody but you will be able to take them. Moreover, engineers also promise to develop a mobile application that will help you open the lock via your smartphone. Unbelievable!

The good news is that the lock shackle is fully covered, so even on a rainy day, the moisture won't get inside. By the way, the chain itself is also covered with a special nylon cover to protect your bicycle from potential scratches. The chain length makes 1 meter, and if you need a longer model, you can choose from 1.2m, 1.5m, 1.8m and even 2m options. So, if you are looking for a long uncuttable chain lock to secure both wheels and brakes, you are in the right place.

Additionally, we suggest you pay attention to bike covers to prolong the lifespan of your two-wheeled vehicle.

OnGuard LK8012C

Protected by Bulldog

OnGuard is one of the most famous companies producing locks for bicycles. Their locks are known for a great build quality and attractive price. The company uses quite an interesting concept since each of their locks is named after a different dog breed, and the more aggressive the breed the more secure the lock.
This very model is called Bulldog Combination U-Lock Cable Combo. As the name suggests, it's a U-shaped lock combined with a durable braided steel cable. So, you get two levels of protection in one compact device! Note that the lock operates with a code mechanism, so all you have to do is set a four-digit combination. No more keys to forget! The superior protection from pick attacks is provided by a special steel ball click-combo gear system, while ultra-hardened steel shackle guarantees maximum cut resistance. As a bonus, the cable can not only secure the wheels but also prevent them from spinning when the bike is installed on a car rack.
The lock boasts a double rubber coating to protect your bike from unwanted scratches. And of course, like all OnGuard Locks, the Bulldog Combination U-Lock is completely protected from moisture and dust. Finally, we would like to add that the lock set includes a multi-position mounting bracket for convenient transportation.
The OnGuard U-lock along with a super-sturdy steel cable is a rare beast that is just unbeatable! Don't hesitate any longer. Provide your bike with luxury protection!
Review of OnGuard LK8012C

Bicycle Capital of the World

Amsterdam is one of the most "bicycle-friendly" cities in the world. More than a third of all trips there are made by bicycle. No wonder that on average each citizen has a bike. Yet, more bikes mean more thefts. According to statistics, in 2001 16% of Dutch people were left without their bicycles. Later, in March 2004, authorities have developed a special program to catch thieves. According to this program, some bikes were equipped with special sensors connected to a global navigation system. The police left the bikes in high criminal areas to find out who was stealing bikes. As a result, it was detected that 40% of criminals were professionals stealing several bicycles per one night. 30% of thieves were addicted to drugs. The rest turned to be so-called "occasional thieves" who just borrowed bikes to get home since they were dead drunk.
