Kryptonite New York Fahgettaboudit Mini
The Kryptonite New York Fahgettaboudit Mini is a top contender, known for its exceptional strength and security. Despite its high price, it's widely considered the strongest lock available, earning a perfect 10/10 rating from Kryptonite. The company even offers a substantial replacement guarantee in case of theft.
Its compact size makes it highly portable, easily fitting in a belt or small bag. However, this small size might limit its use with larger objects, requiring careful consideration of your locking points.
Abus Granite XPlus 540
The Abus Granite XPlus 540 prioritizes durability above all else. Its sturdy, square U-ring resists leverage attacks better than circular designs. Even if cut, the square shape increases the time and effort required for theft.
Its dimensions provide a good balance between portability and strength. Many other locks are either too large to carry easily or too small to secure effectively. This lock solves that problem.
Litelok GOLD Wearable
The Litelok GOLD Wearable is exceptionally lightweight at 1.12kg, yet surprisingly strong. Its flexible design allows for convenient placement anywhere, even around your waist.
Made from a tough, flexible material called Bowflex Secor, it resists both pulling and cutting attempts exceptionally well. Different lengths are available to fit various bike and anchor sizes.
Kryptonite Kryptolok Series 4 1055 Mini Chain
Chain locks, while potentially less convenient than U-locks, offer the advantage of flexibility in securing your bike to larger objects. The Kryptonite Kryptolok Series 4 offers this flexibility with a compact 55-inch chain.
Its integrated locking mechanism is secure and easily operated, and it's lightweight and foldable, making it suitable for backpacks. Despite its thinner chain width (10mm), it maintains a high security rating.
Abus Bordo Granite XPlus 6500
The Abus Bordo Granite XPlus 6500 foldable lock provides convenient storage and portability, coming with a bike mount for easy attachment. While heavier (1.58 kg), its superior security justifies the weight.
It receives a top 15/15 rating on the Abus safety scale. The foldable design increases the number of potential locking points compared to U-locks, though U-locks generally offer better security.
OnGuard Pitbull STD U-Lock
The OnGuard Pitbull STD U-Lock offers excellent value, combining gold-rated security with a significantly lower price than many competitors. Its lightweight (1.77kg) design is also convenient.
Features include rubberized vinyl coating to protect your bike's frame, and an included LED light for easier key insertion in low-light conditions. A cable extension is also provided.
Abus SmartX 770
The Abus SmartX 770 combines robust Abus design with smart technology. It uses a keyless go card and Bluetooth connectivity, controllable through the Abus app.
Features include a built-in alarm and bike-finding functionality. This high-tech lock offers convenience and security, but at a higher price point than traditional locks.
Kryptonite Kryptolok 955 Mini
The Kryptonite Kryptolok 955 Mini offers improved security over a standard U-lock with its double-sided locking shackle, increasing its security rating to Gold.
While maintaining mid-range security, its ease of use and lightweight design (comparable to 3.5 cans of coke) make it a practical and convenient choice. The generous shackle size makes locking easier.
Kryptonite Kryptoflex 955 Mini Chain
The Kryptonite Kryptoflex 955 Mini Chain lock provides a good balance of security and portability. Its flexibility allows for securing your bike to various objects.
While heavier than comparable U-locks, its Gold rating signifies its effectiveness. The integrated locking mechanism simplifies the locking process compared to locks with separate padlocks.
Hiplok Gold Chain
The Hiplok Gold Chain is unique for its wearability, allowing it to be worn like a belt around your waist, making it far easier to carry than traditional heavy chains.
Although heavy (2.2 kg), the weight distribution makes it more manageable than carrying a similarly sized chain in other ways. The gold rating ensures a high level of security.
