10 Best Bicycle Locks 2025 in the United States

The Seatylock FoldyLock Compact Folding Bike Lock is designed for cyclists seeking a blend of security and portability. Its patented folding mechanism and compact size make it a convenient choice for urban riders who need to secure their bicycles in various environments. Weighing 2.2 pounds, it strikes a balance between being lightweight and robust. The use of hardened steel covered with nylon and glass fibers ensures durability against theft attempts, including bolt cutters and drills. This lock provides a 33.5-inch circumference when unfolded, sufficient for securing a bike to most stands or racks.

Strengths of this lock include its high-security rating, bolstered by anti-tamper rivets and a weatherproof design, making it suitable for varied weather conditions. The lock’s quiet operation and easy installation add to its user-friendly nature. The product comes with a three-year warranty, providing peace of mind regarding potential defects. Its design has been recognized with a European Design Award in 2020, underscoring its innovative approach.

However, some might find the 33.5-inch circumference limiting for certain locking scenarios, particularly if needing to secure both wheels and frame simultaneously to a fixed object. Additionally, while the lock is portable, carrying it on smaller frames might be cumbersome despite the included mounting case. The use of keys instead of a combination mechanism might be less convenient for some users who prefer not to carry extra items.

This lock is best suited for city cyclists who prioritize security without sacrificing portability. It offers a solid protection level for standard use and is particularly appealing due to its lightweight design and strong build, though it might not cater to those needing extra-long locks or keyless entry solutions.

The Hiplok Z LOK is a lightweight bike lock that stands out mainly for its portability and convenience. Weighing only 20 grams, including the key, it’s one of the lightest locks you can carry. Its flexible design uses a toughened nylon outer layer with a reinforced steel core, providing a reasonable balance between flexibility and security. The lock uses a key mechanism, which is straightforward and reliable for most users.

With a 40 cm locking diameter, it’s best suited for securing smaller parts of your bike or locking it to thin posts or railings. The multiuse, reusable zip-like design means it can be wrapped and secured quickly, making it handy for short stops or low-risk environments. The alloy steel material offers decent durability, but this lock is not as robust as heavier, thicker U-locks or chains – so it’s less ideal if you need maximum protection in high-theft areas.

In terms of size, the lock is compact and slim (around 16.5 inches long and less than an inch wide), making it easy to store or carry without adding bulk. The powder-coated finish helps protect it from weather damage. If you prioritize a lightweight, easy-to-use lock for quick, low-risk locking, the Hiplok Z LOK fits well. However, if you need high security for leaving your bike unattended for long periods or in risky locations, this lock might not provide enough protection. It’s a good choice as a secondary or travel lock, especially for cyclists who want something minimal and flexible rather than heavy and rigid.

The Kryptonite New York Standard Bike U-Lock is a robust choice for anyone looking to secure their bicycle, e-bike, or scooter. One of its main strengths is its 16mm hardened steel shackle, which is designed to withstand cutting and leverage attacks, making it a strong deterrent against theft. With an anti-theft protection offer that provides up to $4,000 in reimbursement for one year, users can feel more secure knowing there's financial backing should a theft occur.

The lock's size and weight are also noteworthy; it measures 3.15 x 1.18 x 1.18 inches and weighs 4.45 pounds, which is manageable for most cyclists. The included mounting bracket allows for easy transportation on your bike, making it convenient to carry around without hassle.

On the downside, some users may find the lock to be a bit heavy compared to other options on the market, which can be a consideration for those looking for ultra-lightweight solutions. Additionally, while the key safe program is a fantastic feature, it might not be ideal for those who prefer keyless options, as you still need to carry physical keys. The lock's weather resistance is a plus, ensuring that it can withstand various outdoor conditions, although prolonged exposure to harsh elements can still take its toll.
