A bike lock is a good solution for protecing your bike from theft, but with so many different models on the market, the search isn’t as easy as you would think because there are so many choices on the market.

Some are quite heavy and hard to carry around. Many of those you’ve seen around aren’t that reliable and can’t protect your bike the right way.

Why do you need a bike lock?

People often think they need a lock for thier bikes only when they are leaving their bike unsupervised for hours at the time. That’s not true since a thief needs only a few minutes to take your bike. The general rule is that you should lock your bike regardless of the time it’s going to stay parked. 

Sometimes, you’re going to need to leave your bike right outside the store, for example. If you accidentally stay inside for longer than you planned, you might not find your bike where you left it.

What to look for in a lock?

There are many models to choose from on the market. Still, remember that not all of them are good and reliable. One of the most important things to look for is efficiency because you want this lock to protect your bike.

It’s also crucial that the lock is just the right weight. This is often not among the first things people consider when buying bike locks even though the factor is essential. The last thing you want is a heavy lock that you’d have to carry around always. It’s inconvenient and unnecessary.

On the other hand , if the lock is too lightweight, it’s probably not as secure and might enable thief’s to steal your bike.

So  which lock should you choose?

It’s best if it’s lightweight, but not like those cheaply made feather-like models we’ve seen around the market. Weight is directly linked to how secure the lock is so this is an important matter to think about.

Stick around as I tell you about the top five lightweight bike locks. Each of these has unique features and specifications that bring reliability, longevity, and efficiency. 

1. Abus Granit X-Plus 54 Mini Key Bicycle U Lock

Key Features:

  • 13Mm Square
  • 2.8 pounds lbs
  • Double Bolted Shackle

Its ratings tell you enough about how secure the lock is. It has a 13mm parabolic shackle, so the entire thing weighs about 2.56 lb. or 1.16 kg. It may seem unusual for a lock that’s as secure to be as lightweight.

Keep in mind that this is a mini U-lock, so it’s small measuring 4.23 x 5.51’’ (10.8 x 14 cm). Being that it’s a small U-lock, it’s quite wide, so you have several locking options.

It’s the type of high-security  that’s not too heavy, but secure enough to deter would be thief. The lock comes with two keys, convenient if you share your bike. If not, keep one key as a reserve. One of the keys is LED-lighted. The security level of the lock is at 15 which is secure for a lock this lightweight.

The Abus Granit X-Plus 54 Mini features an automatic keyhole cover. It protects the keyhole from corrosion and dirt, so the lock lasts longer with the same quality.

The lock doesn’t come with a bracket. However, you can use the ABUS TexKF Square Shackle Clamp that’s 13mm. The TexFK Twin or RBKF Twin brackets would also do the job. To make them work, you’d probably need to cut the plastic housing off a tiny section of the U shackle.

It may not be the most affordable bike lock, but it’s among the most secure and reliable ones. It’s a traditional lock that has remarkable security to weight ratio that guarantees efficiency. If you’re looking for a reliable safety lock that doesn’t weigh a ton but also not super lightweight, this might be the best bike lock for you.

4. Kryptonite New York U- lock

Key Features:

  • High risk area approved

Kryptonite is probably one of the most popular safety locks people go for. It’s no wonder they are as successful since their founder shares the same passion for bike locks as many of us. His goal was to create a lock that would provide security from bike thefts in New York. He succeeded and created this bike lock that is the ultimate choice.

A U-lock is by far the best thing you can get since the design is the most difficult to break. This lock has a 14mm thick shackle that makes it resilient to most cutting tools a thief would use. It’s of standard size, measuring 4’’ x 8’’.

It weighs about 4.35 pounds, which isn’t the most lightweight bike lock. Still, the weight is because of the materials used to achieve quality. For this reason, the extra weight is worth it and another reason why it made our list of lightweight bike locks.

This lock has a double deadbolt locking and is one of the very few on the market that features the system. It means both U-shaped shackle ends are bolted, so the thief has to cut the shafts.

5. ABUS Bordo 6000 Folding Bike Lock

Key Features:

  • 5 mm steel bars
  • Comes with 2 keys
  • Adult folding frame

If you have a folding bike and a U-lock is tricky for you to carry, consider a folding bike lock. The ABUS Bordo 600 Folding Lock provides medium safety level, but it’s easy to use and carry around. 

ABUS rated the lock to be 10/15 on a safety scale, so it’s recommended only for medium risk. Sold Secure gave it a Silver rating which means the same thing.

This is because folding locks aren’t as safe as U-locks. Its steel bars are thinner than U-lock shackles. The pins that hold these steel bars together are also a bit fragile.

Steel bars of the Bordo 6000 are 5mm thick. This is precisely you should only use the lock in medium risk situations. The bars aren’t thick enough to fight off bigger bolt cutters. If you don’t live in a risky place or own a very pricey bike, you’ll be fine.

Still, the most prominent feature of the lock is its compact shape and ease of use. The lock collapses down into a small package that’s easy to carry around. Unlike with U-lock where the center of gravity is always away from the frame, this folding lock sits very tightly against the frame.

It’s unlikely to go loose, even less to fall off. It comes with a sturdy rubber frame mount and allows you to attach it in two ways. If you have a bottle carrier on your frame, you can connect the lock there. If not, use the two Velcro straps to mount the lock on your bike.

It takes up very little room in your bag since it’s just 7.75’’ x 2.5’’ x 1.25’’ (20 x 6.5 x 3 cm) in total. Its size allows you to transport the lock with ease in your bag or purse. It’s also lightweight at only 2.27 lb. (1.03kg).

If you have a folding bike and need a lock that’s easier to use and carry than a U-lock, this is an excellent choice for you. This folding lock is convenient and ideal for people who want something more straightforward. In medium risk situations, it provides best protection and ease of use you can find for your folding mountain bike.


  • Small and convenient to use
  • Pairs great with a folding bike
  • Easy to transport and store
