10 Best Folding Bike Lock 2026 in the United States

The Seatylock FoldyLock Forever is a strong folding bike lock set designed especially for riders who want serious protection for their bikes. Made from hardened steel with a tough nylon and glass fiber cover, it offers excellent resistance against cutting, drilling, and weather damage. Its maximum security rating (18/18) means it’s one of the safest locks you can get, making it great for urban cyclists, e-bike owners, and those in high-theft areas. The set includes two locks with six identical keys, which is handy for couples or families needing to secure more than one bike. Each lock measures 35.4 inches in circumference, giving enough length to secure your bike to various fixed objects.

Weighing about 3.87 pounds for the pair, it’s portable but a bit heavier than simpler cable locks, reflecting its sturdy build. Mounting brackets are included to attach the locks quietly and conveniently to your bike frame, which helps carry them comfortably and stops rattling noise during rides. The locks fold neatly into compact shapes, making them easier to store when not in use.

The heavyweight nature might be a bit cumbersome for those looking for ultra-light gear. Also, while the folding design is more flexible than a rigid lock, it might not wrap around very large objects as easily as a long chain lock. However, for those prioritizing security and durability, this set offers strong protection and practical features, along with a 3-year warranty for peace of mind.

It comes with three keys and a mounting bracket that attaches quietly to your bike frame without rattling, which is convenient for daily use.

The foldy design is compact and portable but may not cover as large an area as some longer cable or chain locks. Also, because it uses physical keys rather than a combination, you need to keep track of the keys to avoid being locked out. The 2.2-pound weight is light for a heavy-duty lock but still adds some bulk to carry. The Seatylock FoldyLock is a solid choice for those seeking a high-security, durable, and easy-to-carry folding lock, especially suited for city riders who prioritize strong theft prevention and appreciate the convenience of a compact lock with a quiet mounting system.

There are a few drawbacks to consider. While the weight is manageable, it might still be cumbersome for some who prefer ultra-lightweight options. Additionally, the folding mechanism requires a bit of effort to get used to, which may not be ideal for all users, especially those looking for a quick, hassle-free locking experience.
