Foldylock Forever - Best High-Security Folding Lock
The Foldylock Forever breaks the mold by delivering Gold-standard security in a highly convenient folding design, perfect for cyclists who value flexible locking options and easy transport.
- +Unique 6.5mm thick hardened steel plates provide a Sold Secure Gold rating in a folding format.
- +35.4-inch length offers superior flexibility to secure bikes to a wider variety of objects like traffic lights or signs.
- +Folds into an extremely compact and easy-to-carry package that mounts securely to the bike frame.
- -As a folding lock, it is inherently more complex and may have more potential failure points than a monolithic U-lock.
- -Heavier than many U-locks with similar security ratings, weighing 3.88 lb (1.76 kg).
- -While highly secure, it does not offer the same specialized angle grinder resistance as the top U-locks.
The Foldylock Forever addresses a key dilemma for cyclists: the need for high security without the rigidity and limited locking options of a traditional U-lock. It achieves this by using 6.5mm thick hardened steel plates linked by patented, protected rivets. This construction earns it a Sold Secure Pedal Cycle Gold rating and a 3-star ART rating, making it the most secure folding lock currently available and suitable even for mopeds. Its real-world advantage is flexibility. Unfolded to 90cm (35.4 inches), it can easily wrap around large, irregular objects like street signs, traffic lights, or thick tree trunks that are impossible for a U-lock to engage.
This versatility is invaluable in areas with poor cycling infrastructure. When not in use, it folds down into a neat, rectangular block that slides securely into a frame-mounted holster, offering a cleaner and often more stable carry solution than many U-lock mounts. The locking mechanism is smooth and the build quality is high. It is important to note that its security, while excellent for a folding lock, is benchmarked at the Gold level. It does not incorporate the same ceramic or composite materials as the Diamond-rated angle grinder resistant U-locks, so it remains vulnerable to a sustained grinder attack. However, its resistance to bolt croppers, leverage, and picking is formidable. For cyclists in medium-to-high risk areas who prioritize locking versatility and a tidy carrying profile, and who may use a secondary cable for components, the Foldylock Forever is an outstanding and unique choice.
