Why People Love it

  • Put it in your bag or pocket and carry it everywhere you go
  • Super lightweight, user-friendly, and versatile
  • Durable, reliable, long-lasting foldable lock

Folds up small enough to fit in your pocket, built with specially-hardened ABS steel bars, held together by ultra-strong rivets, security rating of 85/100, 3-year warranty and 100% refund policy, lightweight, and user-friendly design.

Locking mechanism design is iffy.

Expert Ratings

Design

9.0 / 10

Design is where this lock comes out a champ: six 7.5-inch sections unfold to produce a loop that you can wrap around a pole or locking bar, then snap into place to secure the lock.

It folds up small enough to fit in your pocket, but will be long enough to lock your bike to most bike racks or locking stations. Thanks to its durable construction—ABS hardened steel, highly-durable rivets, and a plastic coating to protect your bike’s paint—you’ll find it does an amazing job of keeping your bike safe.

Weight and Size

9.0 / 10

At less than 2 pounds in weight, it’s light enough to carry around in your pocket, purse, pouch, or backpack. When unfolded to its full length, the lock is nearly 4 feet long—more than long enough to wrap around most bike racks or locking stations.

Versatility

8.5 / 10

Versatility is definitely guaranteed with this bad boy! It’s designed to lock up to two bikes at once, and you’ll love how flexible the unfolding lock is when wrapping it around thicker posts and bars. The lock even comes with a bottle cage mount and Velcro straps to ensure that you can mount it easily, and it’s hassle-free when unlocking and stowing it in your bag once you’re done.

Durability

8.0 / 10

The unfolding sections themselves are very durable—made with high quality steel and held together by rivets that are nearly unbreakable. The lock, however, is where users have the biggest complaints. Not because it’s weak or vulnerable to thieves, but due to its susceptibility to the elements. Users have noted that leaving the lock out in the rain, snow, or cold makes it prone to sticking, so much so that it can break the keys or refuse to turn.

Value

8.5 / 10

At less than $30, this bike lock is VERY high value, and a great security device to purchase at a price you can love. Thanks to its 3-year warranty and 60-day money back policy, you’re guaranteed to get what you want out of this lock.

Why People Love it

  • Compact and portable, fits in any bag or backpack
  • Easily secured to any locking bar, rack, or post
  • User-friendly, versatile design, highly durable

Secure your bike to any fence post, parking meter, bike rack, or street lamp; nearly impossible to cut, easily folded for compact storage, the most unique lock design on the market, and lifetime limited warranty included.

Heavy, locking mechanism prone to jamming, and the chain is fairly short.

Expert Ratings

Design

8.5 / 10

These look like a pair of handcuffs, but made specifically for your bike! Each cuff locks around your bike’s frame and the chain is long enough to wrap around most racks or locking bars. Plus, the cuffs can also be locked around 3-inch thick posts or bars, making it easy for you to lock up the bike anywhere you are!

Weight and Size

8.5 / 10

The lock is surprisingly heavy—nearly 3.5 pounds—and the entire assembly is 21 inches long. The chain itself is long enough to wrap around thinner poles, allowing you to lock both cuffs to your frame.

Versatility

8.5 / 10

The cuffs are what makes this lock so versatile! You’re not limited to an inflexible shape (like a U-lock) or wrapping the lock around a post (like with a chain lock). Instead, you can actually “handcuff” your bike to any post or locking bar. Thanks to the durable design, you’ll never have to worry about your “prisoner” escaping or the lock being broken!

Durability

8.0 / 10

The lock is incredibly durable—both the chain in the center and the handcuffs themselves. The hardened laminated steel links are nearly impossible to cut, and the pivoting links prevent thieves from getting any leverage on the chain to break them. The handcuffs themselves are also very durable and thief-resistant, with a lock that will be incredibly difficult to pick.

The only downside is that the locking mechanism, while very solid, is prone to jamming. You’ll have to take extra care of it (oiling and proper maintenance) to keep it working well for years to come.

Value

9.0 / 10

At just $50, this is an amazing deal for a lock that will be highly versatile and reliable. Definitely worth considering if you want quality at a good price.

Why People Love it

  • Incredibly durable and brilliantly easy to lock up your bike
  • User-friendly design, leaves your bike safe in two seconds
  • No fuss with chains, shackles, or locks—one click and you’re ready to go

Lightweight, compact, easy to carry around as you ride, highly secure, takes two seconds to lock your bike, no key required to engage lock, incredibly durable, PVC-coated to protect your bike, and very versatile.

Plastic mounting clip is not very secure, and you could potentially lose your bike lock when mounted.

Expert Ratings

Design

9.0 / 10

The design of this lock is brilliant in its simplicity: it’s a single D-shaped piece of metal that can be slipped over your bike’s frame and any locking bar. It takes two seconds to replace the push-button lock and snap it into place—locked and ready to roll with no need to fiddle with chains, shackles, or key-operated locks.

Weight and Size

9.0 / 10

At just 0.9 pounds, this is one of the lightest locks on the market, yet its size (7.5 inches long by 4 inches at its widest) makes it easy to slip over any locking bar, bike rack, or post.  

Versatility

9.0 / 10

It may not look very versatile—a single oddly-shaped hoop of steel—but you’ll find it works on more racks, stands, and posts than most U-locks. The fact that you can open the ends of the lock makes it easy to slip it over any post or bar for quick and easy locking.

Durability

9.0 / 10

The fact that this is made of a titanium alloy means that it’s incredibly durable and nearly impossible to cut. The design of the lock prevents thieves from using leverage attacks on the lock itself, and the push-key lock is deceptively strong. You’ll find it’s able to withstand pretty much anything short of an electric torch!

Value

9.0 / 10

The lock itself is excellent value, despite its high price. If you want to keep that high-priced bike safe anywhere you are, this is the lock for you!

Why People Love it

  • The heaviest-duty bike locking chain on the market
  • Titanium-reinforced steel is nearly unbreakable
  • Thick, heavy, and absolutely solid!

Security rating of 99, titanium-reinforced steel 14-mm thick chain, comes with disc lock included, vinyl-coated to protect your bike, ideal for high-crime areas, can defeat even angle grinders, and comes in 3.5 and 6-foot long options.

Chain is very heavy, lock may damage your bike as you ride, and locking mechanisms not the most durable.

Expert Ratings

Design

9.5 / 10

This combination of cylinder U-lock and heavy-duty bike chain is ideal for locking up your bike anywhere you go. The 14 mm-thick titanium-reinforced steel chain is capable of keeping out anything short of a cutting torch, and it’ll guarantee your bike stays locked up safely no matter where you are.

Weight and Size

8.5 / 10

At 16 pounds, this lock and chain combo is VERY heavy—perhaps too heavy for some people to carry. It’s definitely better off left in one place (at home or at work)!

The chain comes in two lengths: 3.5 and 6 feet long, making it easy for you to find the size that works best for you.

Versatility

9.0 / 10

Thanks to its chain length, you can secure it to literally any locking bar, post, or bike stand. The heavy vinyl cover will protect your bike from damage, though some users have complained that the lock itself will bang up your bike bad if you ride with it dangling.  

Durability

9.5 / 10

The chain itself earns a 99-of-100 security rating, thanks to its titanium reinforcement and extra-thick design. The lock itself, however, may be a bit flimsier. Even with the 5 laser-cut keys (1 with a built-in micro light), you may find that the locking mechanism breaks far more easily than the chain itself.

Value

8.5 / 10

Starting at just under $90 for the 3.5-foot chain, this bike lock is as heavy duty as it gets, making it perfect for use in high-crime areas. Though you may end up having to buy another cylinder lock down the line, the chain itself will stop just about anything thieves can throw at it.

Why People Love it

  • Highly secure, nearly impossible to break or cut with anything short of a cutting torch
  • User-friendly design, incredibly durable and damage-resistant
  • Perfect for high-risk areas and high-priced bicycles

Super heavy duty steel shackle, double-thick steel, reinforced crossbar, design reduces effectiveness of leverage attacks, pick and drill-resistant cylinder lock, dustcover, comes with three keys, hacksaw proof, and vinyl-coated to protect your bicycle

At more than 4 pounds, this lock is a beast!

Expert Ratings

Design

9.5 / 10

This U-lock is designed to be highly secure: an 18mm-thick hardened steel shackle locked onto a steel-sleeved crossover bar with a built-in double deadbolt design and a disc-style cylinder lock that is resistant to both picking and drilling. The protective vinyl coating isn’t intended to increase security, but it’s guaranteed to reduce scratches on your bicycle!

Weight and Size

9.0 / 10

The lock is VERY heavy—more than 4 pounds—and one beast of a security device! The added weight of the extra-thick shackle makes it twice as secure as your average U-lock, and far more resistant to bolt cutters and hacksaws. At 6 inches in length, it’s more than long enough to secure your bike to any bike stand.

Versatility

8.0 / 10

U-locks are the least versatile around, especially when they’re shorter (like this 6”-long lock). The shackle will work for most bike stands, but any post or pole thicker than 3 inches is too thick for this lock to fit around.

Durability

9.5 / 10

This is where the Fahgettaboutit shines! Thanks to its hardened double deadbolt design, thieves have little chance of defeating the lock with a leverage attack. The disc-style cylinder lock is nearly impossible to pick or drill, and it’s covered with a dustcover to keep it safe from the elements (rain, dust, snow, etc.). With its extra-thick locking shackle, thieves are going to need a cutting torch to get through this bad boy!

Value

9.0 / 10

Though it’s pricey, it’s definitely worth every penny if you’ve got a higher-end bike you want to protect.
