Its hardened steel plates and patented anti-tamper rivet system make it a strong choice for city cyclists who need serious protection without carrying a bulky chain or U-lock.
Does the Seatylock Foldylock Forever offer enough security for expensive e-bikes and electric scooters?
Yes, the Foldylock Forever is rated 18/18 on the Sold Secure scale and carries a Sold Secure Gold certification, placing it among the highest-rated locks available for protecting high-value vehicles like e-bikes and electric scooters.

Unlike a chain lock, the Foldylock Forever folds down to a compact 8.1 x 2.71 x 1.85 inches, making it far easier to carry daily without sacrificing security. It matches or exceeds many U-locks at this security level, holding both Sold Secure Gold and ART 3 Stars ratings, while offering a more flexible 90cm reach to lock to a wider range of bike racks and posts.

Does the Seatylock Foldylock Forever stay secure and rattle-free when mounted to a bike frame during a ride?
Yes, the lock comes with a adedicated mounting bracket, mounting straps, fixing screws, and an Allen key specifically designed to hold the lock firmly to your frame without vibration or noise.
