Seatylock Viking Silver 90 is a lightweight bicycle chain lock built for cyclists who need reliable everyday security without added bulk. As part of the Seatylock Viking Series, it is one of the world's only chain locks featuring a patented magnetic closure, making locking and unlocking faster and more intuitive than traditional mechanisms. Its 7mm hardened steel square links resist cutting better than standard chains, while an automotive-grade cylinder adds a further layer of protection. A water-resistant neoprene sleeve guards your bike's frame from scratches, and an auto-shutter keyhole cover keeps the lock weatherproof through daily use.

The lock body is wrapped in a protective silicone cover, shielding both the lock and your bike frame from scratches and scuffs. This soft layer also cushions contact points so your paintwork stays in great condition ride after ride.
Viking Silver 90 features a dual sleeve mechanism combining a neoprene chain sleeve and a silicone cover, giving your bike frame a layer of protection wherever the lock rests. The neoprene sleeve also dampens chain noise, so you get a quieter, rattle-free ride.
As part of the Seatylock Viking Series, the Viking Silver 90 is among the world's only chain locks to feature a patented magnetic locking mechanism, making it a genuinely rare design in the cycling security market. This innovation means you can lock and unlock the chain with one hand, quickly and without fumbling.
The 7mm square-shaped hardened steel links are engineered to resist cutting tools better than standard round-link chains. This construction gives you dependable everyday protection whether you're locking up at the office, a café, or a busy bike rack.
The lock cylinder is built to automotive standards, offering smooth, precise key operation every time you use it. An automatic keyhole cover seals out water, dirt, and dust, keeping the mechanism working reliably through all weather conditions.
Viking Silver 90 holds a Sold Secure Silver Certification and carries a 12/18 internal security rating, giving you independently verified protection for daily urban cycling. It strikes the right balance between solid security and a lighter carry weight compared to higher-tier chain locks.

I like the magnet patent
I Love it so much that I asked my local bike shop this morning (Saipan Bike Pro) to start buying them wholesale, so we can purchase more. They initially offered me another brand, but I said NO. I already got robbed once with a cheap lock and recovered it 2 weeks later, Now I just purchased a new Cannondale Trail 7 (30 June 2023). This morning (26 July 2023) I just ordered 2 new bikes for my young Niece & Nephew (age 7 & 9) and 'REQUIRED ONLY SEATYLOCKs'!!! Thanks Again, from a New Valued Customer!
I purchased two of these for our bikes and couldn't be happier with this product. It's light enough to throw in a backpack or wrap around the bike frame for transport but it's solid enough to present a real deterrent to any would-be thieves. I'd recommend this bike chain to anyone!
The lock has a great feel. Very nice sleeve that won't scratch a frame. I feel confident in it. Shipped out quickly and fair price compared with other brands. Will look to this company for any future security needs
I have been eyeing the seatylock locks for a bit, and I caught a sale on the viking light 90 over the holiday that gave me the extra nudge to give this lock a try! I needed a lock that is smaller & lighter that still feels sturdy and secure for an electric scooter I'm using to commute to work and take on errands. What I really like about this lock is that there is just enough chain length to wrap one time around the front tube of my e-scooter and then around a pole or bike rack so that there's no leftover slack - it gets a snug fit so I can feel confident that the lock and scooter are all going to stay in one place while it's locked up. It doesn't add much weight to my backpack either (it's lighter than my laptop). The neoprene sleeve around the chain is a nice touch, and the locking mechanism is much better than top lock brands like kryptonite (have had issues with my krpyto locks seizing up, rendering them unusable). I have high hopes that the locking mechanism will withstand the elements of a Chicago winter, and spring/fall rains!!
