bike locks heavy duty anti theft,bicycle lock,bike u lock,bike lock with key,ulock bike lock, u lock

We Tested the Mason U-Lock By Using a Wide Variety of Stress Tests, Simulating Real-Life Attack Strategies by Thieves:

Bolt Cutter

A Bolt Cutter is One of the Most Common Theft Strategies Used by Thieves. But A Standard Bolt-Cutter is No Match for Our Mason U Lock! The Lock Wasn’t Broken By a Bolt Cutter.

Carbide Hacksaw

Our Mason U-Lock is So Strong That Even a Carbide Hacksaw Isn’t Enough to Saw Through the Solid Secure Metal. A Thief with a Hacksaw is Out of Luck with the SeatyLock Mason U-Lock.

Crowbar

Our Patented Triangular Crossbars & Double Deadbolt Make the Mason U-Lock Immune to Crowbar Prying & Twisting Attacks! We Passed the Crowbar Test with Flying Colors.

Freeze Attack

We Saved the Best for Last! Using Liquid Nitrogen to Freeze & Weaken the Metal on the Lock, Our Lock Remained Solid & Secure. Even a Freeze Attack Couldn’t Break the Mason U-Lock.

5.0 out of 5 stars This is the lightest Sold Secure Gold lock I found on amazon.
By Atomic on June 17, 2019
Great lock, sleek design. I leave my bike outside attached to a bike rack, while I'm at work and seems to me that no one could cut through this with bolt cutters or a hack saw. Even with an angle grinder it's probably going to take a lot of work to cut through this bad boy.
