Key Features and Benefits

World's Strongest

The Foldylock Forever holds ART 3 Star certification, making it one of the very few folding locks in the world to reach this level, and placing it among the strongest folding bike locks you can buy. This lock meets the highest independent security standards recognized across Europe and beyond.

Hardened Steel Core

Every link is forged from hardened steel plates wrapped in a reinforced nylon and glass fibre cover, built to resist bolt cutters, saws, and impact attacks. The patented anti-tamper rivets add a further layer of protection against side attacks, a common weak point in lesser folding locks.

Quiet Frame Mount

The included mounting bracket secures the lock directly to your frame, eliminating the rattling noise that ruins a ride with a loosely carried lock. It fits most bikes and e-scooters, keeping the lock stable, silent, and always within reach.

90 cm Reach

When unfolded, the lock opens to a 90 cm circumference, giving you enough reach to secure your frame and wheel to a rack, post, or street furniture. When folded, it packs down to just 20.5 x 6.9 x 4.7 cm for easy storage or carrying.

Weatherproof By Design

The hardened steel and polymer construction is waterproof, weather resistant, and corrosion resistant, so the lock performs just as reliably in rain or winter conditions as it does on a dry summer commute. No maintenance routine is needed to keep it functioning year after year.

3-Year Warranty

Every Foldylock Forever comes with a 3-year manufacturer warranty against product defects, so your investment is protected from day one. Three automotive-grade keys are included, along with a key duplication card that lets you register and order spares should you ever need them.

FAQ

Does the Foldylock Forever hold any independent security certifications that place it among the most secure folding bike locks available?
Yes. The Foldylock Forever holds ART 3 Star certification , making it one of the very few folding locks in the world to reach this level and placing it among the strongest folding bike locks you can buy. You can review all certifications on the certifications page.
Is the Foldylock Forever a strong choice for urban commuters who need a secure lock they can carry every day without it becoming a burden?
The Foldylock Forever is built with daily urban commuting in mind. It folds down to just 20.5 x 6.9 x 4.7 cm and attaches directly to your frame via the included mounting bracket, so it stays secure and accessible without adding bulk to your bag. The hardened steel and polymer construction keeps it lightweight relative to its security level, so you get serious protection without a serious carry penalty.
Can the Foldylock Forever withstand bolt cutter and saw attacks, or is it vulnerable to the tools commonly used in bike theft?
Every link is forged from hardened steel plates wrapped in a reinforced nylon and glass fibre cover, engineered to resist bolt cutters, saws, and impact attacks. The patented anti-tamper rivets add a further layer of protection against side attacks, a common weak point in lesser folding locks. This level of resistance is independently verified by its ART 3 Star certification, one of the most demanding standards a folding lock can achieve.
How does the Foldylock Forever compare with standard folding bike locks?
Most folding locks on the market achieve a standard security, but the Foldylock Forever goes further with an ART 3 Star certification, placing it in a significantly higher security category. The combination of hardened steel plates, reinforced cover, and patented anti-tamper rivets gives it resistance to attack methods that lower-rated locks simply cannot handle.
Is the Foldylock Forever suitable for securing e-scooters as well as bicycles?
Yes, the Foldylock Forever is designed to work with both bicycles and e-scooters. The mounting bracket fits most frames across both vehicle types, keeping the lock stable and rattle-free during your ride. With a 90 cm circumference when unfolded, it provides enough reach to lock your scooter or bike securely to a fixed object.
What makes the Foldylock Forever's anti-tamper rivet design more resistant to attack than typical folding bike locks?
The joints connecting each hardened steel plate are the most common attack point on a folding lock, and most locks leave these exposed or under-protected. The Foldylock Forever uses patented anti-tamper rivets at every joint, making it far harder for an attacker to use leverage or side-force to force the lock apart. This design is part of what helped the lock earn its ART 3 Star certification, a standard that specifically tests resistance to these kinds of attacks.
Is the Foldylock Forever worth the investment for riders who want a long-lasting lock that performs reliably in all weather conditions?
The Foldylock Forever is built to last, with a hardened steel and polymer construction that is waterproof, weather resistant, and corrosion resistant, so it performs just as reliably in rain or winter conditions as it does on a dry summer commute. No maintenance routine is needed to keep it functioning year after year. Backed by a 3-year manufacturer warranty against product defects, your purchase is protected from day one.
Does the Foldylock Forever provide enough reach to lock both a bike frame and wheel to a fixed object at the same time?
When unfolded, the Foldylock Forever opens to a 90 cm circumference, which gives you enough reach to loop through your frame and wheel and around a rack, post, or street furniture in a single pass. When folded, it compacts to 20.5 x 6.9 x 4.7 cm, so that generous reach comes without a storage penalty.
How does the Foldylock Forever's mounting bracket prevent the rattling and noise issues that affect many folding locks during a ride?
The included mounting bracket is designed to hold the folded lock directly against your frame, keeping it stable and preventing the movement that causes rattling on rough road surfaces. Unlike simply hooking a lock to a bag or tucking it loosely into a cage, the bracket secures the lock in a fixed position so it stays silent throughout your commute. It fits most bikes and e-scooters, making it a practical solution for everyday riders.
What warranty and key replacement options does the Foldylock Forever include, and are they sufficient for buyers who want long-term peace of mind?
Every Foldylock Forever comes with a 3-year manufacturer warranty covering product defects, so your investment is protected from the moment you buy. Three automotive-grade keys are included, and a key duplication card lets you register your keys and order spares if you ever need them. Together, these options give buyers a solid long-term safety net.

Terrific E-Bike Lock

I received two of these locks recently by getting them early through Kickstarter. These locks are fantastic. They are super beefy and super strong. I have never owned a folding lock but I now know why they're popular. I have mine mounted perfectly on my Juiced RipRacer and one on my wife's Lectric E-bike. I love that even with the weight of the lock you do not feel the weight itself when you're riding with it attached to the bike frame. This is so nice to also have ALL the time when riding the bikes. I will note how easy it was to register the keys on this website too. Now we have a 3 year warranty and if we lose the keys we can have ones made if needed. This is great. The lock itself is extremely easy to use to unlock and lock. No complaints there and the way it goes out and into the carrying case on the frame is wonderful. I'm so glad it came with hardware and an Allen key. This made it nice because my Juiced RipRacer did not come with screws where the bottle cage threads were but just plastic plugs. Since it came with the screws this made installation a breeze. I found this so helpful. These locks will be used now every time we go for a ride and need to lock up our bikes. I'm so thankful we got them and were able to mount them to our bike frames.
