Since 2008, Seatylock has been on a mission to redefine bicycle security, not through brute force alone, but through intelligent design, rigorous engineering, and an unwavering commitment to the modern urban cyclist.
We're cyclists first, makers second, and relentless problem-solvers always.
Born from the belief that a city's cycling culture is its lifeblood, Seatylock exists to give riders the confidence to park anywhere, lock quickly, and move through urban spaces without compromise. Because when security becomes second nature, cycling becomes freedom.

Every product we create is built on The Seatylock Triangle: Three interconnected principles that define who we are and what we stand for.
Security isn't negotiable. It's the foundation.
That's why every Seatylock product is designed to meet and exceed rigorous international theft-resistance standards. Our locks are independently tested and certified by some of the world's most respected security organizations.
For example:
But certification is just the beginning. We've developed our own 18-step Seatylock Scale, aligned with Sold Secure ratings, to help riders choose the right level of protection for their environment, without carrying unnecessary weight or bulk.
Security should be smart, not just strong.
Innovation at Seatylock isn't about flash - It's about solving the real, everyday friction points of bike security:
From the original Seatylock hybrid concept, a lock ingeniously integrated into a bike seat, to our flagship Foldylock family and beyond, we design products that eliminate the usual trade-offs between strength, convenience, and aesthetics.
Our innovations are protected by patents across multiple regions, reflecting a long-term commitment to pioneering new categories rather than copying what already exists. We don't follow trends. We set them.
Most bike locks are treated as afterthoughts, purely functional, visually forgettable objects you're forced to tolerate.
Seatylock takes the opposite view.
A lock is a daily companion. It's visible. It's something you interact with constantly. So why shouldn't it be as thoughtfully designed as the bike itself?
Our design-first philosophy has been recognized internationally by multiple design award institutions.
Style isn't vanity. It's respect for the rider, the bike, and the experience of urban cycling.
In an industry dominated by outsourcing and commodity parts, Seatylock stands apart.
We maintain deep vertical integration: designing, producing, and assembling our products in-house, right down to the cylinders and keys. This gives us unparalleled control over:
Quality assurance at every stage
Faster iteration and product evolution
When you choose Seatylock, you're choosing a brand that owns its craft from concept to delivery.
Our product lineup is designed around real rider needs, from high-security urban locking to accessory protection:
Premium folding locks, engineered for portability, strength, and everyday usability. Compact, quiet, and surprisingly tough.
The Foldylock series solved one of the most common weaknesses found in many folding bike locks: They simply aren’t strong enough.
A premium U-lock series built for maximum security across multiple sizes. When you need uncompromising strength, Mason delivers.
For the Mason Series, our goal was clear: to create the strongest lock in the world for its weight.
Viking is built for riders who want serious chain-lock security without the usual hassle.
Heavy-duty chain locks available in multiple lengths and security levels for flexible protection in any locking scenario.
Features a unique, patent-protected magnetic locking mechanism that makes locking noticeably easier than typical chain locks.
The original hybrid innovation: a seat that transforms into a lock. Function meets form in the most unexpected way.
A patented detachable saddle system designed to prevent one of the most common (and frustrating) bike thefts: saddle theft.
Specialized solutions to protect unsecured bike accessories like wheels and saddles, because every part of your bike deserves protection.
ULTRA is our new series of “angle grinder killer” security products, engineered to resist today’s most aggressive theft methods, including angle-grinder attacks.
The first releases are planned for pre-sale in May 2026, with general availability in July 2026.
By the end of 2026, we also plan to introduce a new product line designed specifically for the motorcycle industry.
We don't just make claims. We back them up with transparency:
✅ Independent security certifications from leading international organizations
When you lock with Seatylock, you're not just trusting a brand - You're trusting a system built on accountability.
Because cycling is our passion. And peace of mind is what we deliver.
We build security tools we're proud to use ourselves, so every rider can lock up faster, ride lighter, and feel freer in the city.
If you ride, commute, explore, or rely on your bike every day, welcome.
