Product Description


From the makers of Seatylock, the Seat and Lock Combination bike lock, and the Foldylock heavy duty folding lock, the Mason is backed by a family of premium folding bike locks.

The Mason U-lock offers a high level of security and is rated Gold by Sold Secure, an independent organization that assesses locks and security products for insurance purposes and recommendations to law enforcement and property owners.


This U-lock features newly designed and patented triangularly shaped crossbars that are 30% stronger than round crossbars. Combined with the double deadbolt locking mechanism this U-lock provides trusted protection against would-be thieves. It comes with 3 keys for easy unlocking and the keys can be registered with Seatylock in case of loss. The U-lock is strong, yet lightweight, so it won’t weigh you down while riding.


The U-lock has a number of features that enable it to stand up to tough weather conditions. The metal components are rust-proof and the automatic shutter mechanism keeps dust and water away from the cylinder. Even the plastic cover has UV protection so that the sun’s rays will not damage it.


At Seatylock, we’ve thought of everything, including the damage that other locks can cause to your bike. Our U-lock is made with hardened steel links that are plastic coated to prevent scratching the paint and finish of your bike and the lock is created with a rattle-elimination mechanism to prevent annoying shaking and noise while you are riding.
