Why Kryptonite, the Best E-Bike Locks to Secure Ebike? The expert explains.

The Kryptolok from Kryptonite continues to impress us with its excellent balance of security and affordability. This updated version features a new steel shackle and an enhanced locking mechanism, maintaining its status as a top choice. Its long shackle offers convenient locking options and resists cutting attempts effectively – it withstood over a minute of cutting with an angle grinder in our tests. Although the key mechanism requires precise handling and the shackle can be somewhat sticky, these minor issues don't overshadow its overall performance. Offering a solid mix of versatility and security, the Kryptolok stands out as a Best Buy. Find out more about how it compares to other bike locks in our comprehensive review.

Kryptonite is a well-known name in the bike lock industry, and for a good reason, their locks are consistently among the strongest. Kryptonite gives the Kryptonite Kryptolok a "six" rating out of ten on its internal scale, which means it's designed for medium-risk situations, the same as its predecessor. So before rushing to the store to buy this model of U-lock, assess the situation in which you're looking to secure your bike. The Kryptolok, if used as intended, is a great way to secure your inexpensive commuter in a medium-risk situation. If you ask for more, chances are you'll need a beefier lock.


Initially, we had reservations about the Kryptonite Kryptolok, considering its affordability compared to other U-locks. However, our tests revealed that it surprisingly outperforms many similarly priced models, including its own predecessor. The key to its enhanced security is the 13 mm hardened steel shackle, which proved difficult to cut through. In our tests, it took around 30 seconds to saw through one side of the lock, even when it was secured in a vise. Additionally, we observed that 24-inch bolt cutters were ineffective against it, solidifying its position as one of the more resilient locks we've evaluated.

The standout feature of the Kryptolok is its use of hardened steel in both the U-part and the shackle, a rarity among U-locks in this price range. Typically, the shackle is the more vulnerable component, but Kryptolok's design enhances overall resistance to attacks, offering exceptional value. It features a dual-locking mechanism, requiring two separate cuts to be opened – a feature often seen in more expensive, high-end locks. While the included braided cable shouldn't be used alone, it's useful for securing components like saddles or front wheels. Ideal for small towns or medium-risk environments, the Kryptolok is a robust choice, especially considering that thieves are unlikely to use noisy and conspicuous tools like angle grinders in public. The security of your bike also depends on what you lock it to – the strength of the lock should match the security of the lockup point.

Easy of Transport

Let's be honest: carrying a U-lock is not exactly convenient due to their weight and bulkiness. However, some brands like Kryptonite try to ease this by providing a frame mount with their locks, allowing you to attach the lock to your bike instead of lugging it in a bag. The mount that comes with the lock can be a bit tricky to install based on the instructions provided, but fortunately, there are many online tutorials that simplify the process, even for bikes that don't have round tubes.

The reliability of the Kryptonite Kryptolok's mount raises some concerns. On smooth surfaces, it functions well, but its stability is less certain on uneven roads, although it stays in place. The mount tends to rattle, yet not excessively. Smaller bikes (< 50cm) might not accommodate the lock due to size constraints.

For a bike with a 56 cm frame, the lock fits seamlessly with the provided mount. However, on a 52 cm frame, it occupies the space for a water bottle. Alternative carrying solutions include attaching it to a bike rack or carrying it in a backpack. If the standard mount isn't satisfactory, a third-party mount could be considered, but it's generally a good fit for most bikes.

Setting aside issues with the mount, the Kryptolok stands out as a lighter option among U-locks we've tested, earning it higher marks. The lighter weight is particularly appreciated during commutes involving uphill climbs, although the cable is more conveniently carried in a bag due to lack of an easy mounting solution.

Easy to Use

The Kryptolok lost some points because of its somewhat cumbersome and occasionally sticky locking mechanism, an issue not expected in a brand-new lock. While it always eventually opened, it was slower to operate compared to other locks we reviewed. However, after applying lubricant, this problem was resolved.

The Kryptonite Kryptolok functions like most U-locks of similar size. While U-locks aren't the most convenient type for frequent use, the trade-off for better security is often worth it. The Kryptolok's slightly larger shackle size compared to other U-locks we tested adds to its ease of use in a variety of situations. This is particularly beneficial for bikes with non-standard shapes, such as the step-through eBike used by one of our testers.


U-locks, including the Kryptonite Kryptolok, are somewhat limited by their rigid design. This restricts the range of places you can secure your bike, often necessitating the availability of bike racks for secure locking.

Among U-locks, the Kryptolok stands out for its performance. Its shackle, measuring just over 11 inches in length and nearly 5.5 inches in width, provides ample space for locking a road bike frame, two tires, and a bike rack in most cases. However, it might not accommodate everything if you have a mountain bike or wider tires. The Kryptolok strikes a good balance between versatility and size, being more adaptable than smaller U-locks but not overly bulky.

Do I need to buy Kryptonite Lock?

As for purchasing, the Kryptonite Kryptolok is a solid, budget-friendly choice for moderate-risk areas. If you own a high-end bike or commute through less secure neighborhoods, you might want to consider a more robust lock for enhanced security.
