The braided steel cable and PVC coating can withstand 2.4KN tension and 7KN shear force, which means it’s well-protected against cuts and other attacks.
The NDakter bike lock comes with a mount that you can use to attach it to your bike. It’s also available in several colors like pink, green, yellow, blue, and more. That adds a minor degree of personalization, as you can choose your favorite style. Plus, the cable-only design means it’s a versatile lock that you can use elsewhere. For example, you can lock gates, sheds, multiple bikes, small items, and much more.
How We Decided
While no lock is completely impenetrable, every lock on our list offers adequate protection and security. Whether it’s a thick braided steel cable that’s safe from cuts or a PVC coated shackle that’s suitable for use in all weather conditions, every lock offers incredible protection.
We tried to balance our selection of combination and key-based locks, ensuring both types end up on the list. Ultimately, they offer the most protection from thieves, especially when they employ anti-picking features like the Via Velo Bike U Lock or Kryptonite’s New York Standard U Lock.
Also, we considered both versatility and additional protections. To elaborate, we looked for locks that can be used just about anywhere, meaning they can withstand a variety of environmental and inclement weather conditions. Furthermore, they can all be used for more than just locking up bikes. You could easily use these locks to secure gates, fences, other small items, sheds, and much more.
The weight of the lock or shackle was a minor consideration, too. You want the lock to fit in a bag or attach to a mount without adding much resistance as it’s something you’ll be carrying along on your bike rides. Everything on the list is lightweight and portable enough to carry, without sacrificing durability or security.
Finally, product guarantees and reimbursement programs also add value, so we tried to choose locks offering them. For example, Kryptonite offers up to $4,000 in reimbursement costs for up to one year if a locked bike or belongings are stolen.
Best Bike Lock Buyer’s Guide
The Most Important Features to Consider
- Durability and Weather Resistance
When it comes to a bike lock, durability and security go hand-in-hand. A bike lock could have the strongest lock mechanism known to man, but if the rest of the device is weak it’s not going to make any difference. A thief could merely cut the chain or shackle portion with bolt cutters, leaving the lock technically still secured and downright useless. Therefore, one of the most important features to consider when choosing a lock is the build material and durability of the entire unit, not just a single portion. In most cases, a hard PVC cover will provide weather resistance, while also adding a secondary layer of protection. The shackle is usually made with heavy-duty steel, while the chain or cable is made of woven steel or some variation of that.
- Locking Mechanism and Anti Picking
Coming in at a close second for important features is the type of lock or locking mechanism of choice. Most cable-based locks will use either a key entry system or a combination lock. There are some smart bike locks available these days, which allow you to use a mobile device and companion app to engage and disengage the lock. Keys tend to be safer but they’re easy to misplace, while combination locks also work well. However, with a combo lock, you’ll need to choose a secure code or pin and not something easy to guess.
This feature is hit or miss, so it depends on the lock in question. For the most part, locks will typically include one or two accessories to sweeten the deal. Many include a bike mount, for example, which you can use to fasten the lock or shackle to your bike during trips. Others might include an extra key, key fob, or similar small items. While accessories are not the primary selling point, they do add extra value and are worth considering, especially when it comes to selecting a suitable price range.
Bike Lock FAQs
What Is the Strongest Bike Lock?
The strongest bike lock models employ a combination of durable materials design and anti-theft features. For example, the Kryptonite New York Standard U Lock has a durable steel makeup, but it also has a unique “pass-thru” crossbar feature that prevents other types of cuts and attacks. As for which type of bike lock is the strongest, we recommend either the top pick — Via Velo’s Bike U Lock with Cable — or the honorable mention, Kryptonite’s New York Standard Heavy-Duty Bike U Lock.
What Is the Hardest Bike Lock to Break?
Instead of focusing on the brand of a bike lock that’s the hardest to break, it makes sense to reveal the type. U-style locks are the best, simply because they are difficult to cut — if at all — and they usually employ strong anti-theft features. However, another point to consider is how versatile a lock is. You may want to use the lock for more than just locking up a bike or large item. If that’s the case, the cable-only locks are the best multi-purpose option.
Is There a Bike Lock That Cannot Be Cut?
Realistically and truthfully, no lock is impossible to cut or break. However, some of the strongest locks require heavy-duty tools or equipment to make a dent, like bolt cutters. It means that thieves would have to lug around the equipment making them more likely to be seen or get caught.
Should I Get a U Lock or Cable Lock?
You should select the type of lock you get based on how you’re going to use it. While security and durability are always a concern, something like versatility might swing the vote. Kryptonite’s New York Standard Bike U Lock, for example, is much sturdier and safer than something like the NDakter 4-Feet Combination Bike Lock Cable. A cable is easier to cut. However, a cable lock is also much more versatile and can be used with virtually anything including gates, sheds, small items and much more. Furthermore, a cable still provides a decent layer of protection and most cable locks are strong enough to withstand simple cuts — to sever one a thief still needs heavy-duty equipment.
