Hardened steel plates, patented anti-tamper rivets, and a reinforced nylon cover resist bolt cutters, saws, and impact attacks. The included frame mount keeps the lock silent and secure while riding.

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. Paired with a Sold Secure Gold rating, this lock meets the highest independent security standards recognized across Europe and beyond.
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.
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.
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.
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.
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.

To deterred bike thieves.
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.
