10 Best Bike Locks 2025 in the United States

The Seatylock FoldyLock Compact is a smart choice for those who want strong security without carrying bulky gear. Its patented folding design uses hardened steel with a tough nylon and glass fiber cover, making it resistant to cutting, drilling, and corrosion. The lock has a high security rating, backed by features like anti-tamper rivets and a multi-locking system that help keep your bike safe from theft. Weighing around 2.2 pounds and compactly folding to just over 7 inches, it’s easy to carry and store, especially with two included silent frame mounts that reduce rattling during rides. The set comes with two identical locks and six matching keys, which is convenient for families or couples. It’s also weatherproof, so rain or snow won’t easily damage it.

That said, while folding locks are great for portability, their length (85 cm circumference) might be tight for securing your bike to larger objects like thick poles. Despite being lightweight and compact, it may feel less bulky and reassuring than a traditional heavy-duty U-lock for some users. Installation is straightforward, but if you’re new to folding locks, getting used to the locking mechanism and key system might take a short adjustment.

This lock is particularly suitable for urban cyclists or e-bike riders looking for a blend of portability and solid protection without the hassle of chains or cables.

The Hiplok Z LOK 4 Pack offers a unique approach to bike security with its ultra-lightweight design, weighing only about 20 grams including the key. This makes it incredibly easy to carry without adding bulk, ideal if you want a lock that won’t weigh you down. Made with a flexible toughened nylon outer and a reinforced alloy steel core, these locks balance flexibility with decent toughness, though they won’t offer the highest protection level compared to heavy-duty locks.

The 40cm locking diameter and zip-like design make it versatile for securing smaller parts or accessories rather than securing a whole bike frame to a fixed object. It uses a key locking mechanism, which adds simplicity but means you need to keep track of the key. The locks are powder-coated, which helps resist weather damage, but given their light materials, they may not withstand harsh conditions or serious tampering as well as thicker U-locks or chains.

If you need a lightweight, multi-use security tie for short stops or low-risk areas, this lock fits well. For high-security needs or longer locking times, opting for a sturdier, heavier lock is advisable.

The Seatylock FoldyLock Forever set offers two strong folding bike locks with matching keys, making it a great choice for couples or families who want consistent security across multiple bikes. These locks use a patented folding design with hardened steel plates covered by durable nylon and glass fiber casing, which makes them both tough and resistant to cutting or drilling. With a maximum security rating of 18/18 (Sold Secure Gold), they provide high protection against theft, suitable for city and urban cycling where bike security is a top concern.

The dual-lock set also includes mounting cases that easily attach to your bike frame, allowing quiet and convenient transport without rattling during rides. Weighing about 3.87 pounds each and measuring 35.4 inches in circumference, they balance portability and coverage well, although the weight might be noticeable if you prefer very lightweight locks. These locks are also weather resistant and waterproof, so they hold up well in rain or other outdoor conditions without getting rusty or damaged.

The locking mechanism is key-based with six identical keys included, simplifying key management but requiring carrying keys rather than a combination. Installation and use are straightforward, with included mounting hardware and an Allen key for setup. One drawback might be the price point relative to simpler cable or chain locks, but the trade-off is stronger security and durability. For those seeking robust, reliable protection for their bikes and valuing quiet, compact storage, this set is a solid option, especially for individuals needing locks for more than one bike.
