Ranked #5 in Best Bike Locks
Kryptonite New York Diamond
8 sources$360as of Oct 2

The Kryptonite New York Diamond offers Sold Secure Diamond certification through a synthetic diamond coating that destroys angle grinder discs and a double deadbolt system requiring two cuts to bypass. bennetts.co.uk found the abrasive layer so effective it shredded cutting tools, while slowspinsociety noted this deters thieves by making attacks time-consuming. However, the lock weighs 5.07 lb, limiting portability for daily cycling use. Additionally, internal shackle dimensions are too small to fit over the front wheels of many motorcycles, restricting its utility as a sole lock for larger bikes. This high-security option fits stationary protection needs but is unsuitable for riders prioritizing lightweight convenience or universal motorcycle compatibility.

Strengths
  • — Synthetic diamond coating provides exceptional resistance to angle grinder attacks, tearing through abrasive discs rapidly.
  • — Holds Sold Secure Diamond rating and Kryptonite's highest security certification for bicycles and motorcycles.
  • — Features a hardened double deadbolt system that requires two cuts to free the lock from its crossbar.
Watch-outs
  • — Weighs approximately 2.36 kg (5.07 lb), making it heavy for daily carrying or lightweight cycling use.
  • — Internal shackle dimensions are too small to fit over the front wheels of many motorcycles, limiting its utility as a sole lock.

thebestbikelock found that the proprietary Barronium composite armor makes this lock exceptionally resistant to angle grinders, while bennetts.co.uk confirmed its Sold Secure Cycle Diamond rating validates extreme security against power tools. The heavy 2.1 kg weight and stiff shackle due to tight tolerances make it cumbersome for daily commuting or quick access. Its versatile internal dimensions allow fitting around various motorcycle wheels and bicycle frames without scratching paintwork. This model fits riders prioritizing maximum protection in high-theft areas, but those seeking a lightweight option should look elsewhere.

Strengths
  • — Exceptional angle grinder resistance due to proprietary Barronium composite armor fused to hardened steel
  • — Sold Secure Cycle and Motorcycle Diamond rating, the highest security certification available
  • — Soft plant-based rubber exterior protects bike paintwork from scratches
Watch-outs
  • — Very high price point compared to standard U-locks and other security devices
  • — Shackle can be stiff and difficult to remove from the lock body due to tight tolerances
  • — Heavy weight of approximately 2.1 kg makes it less convenient for daily commuting

How they stack up

Kryptonite New York Diamond

With a Sold Secure Diamond rating and synthetic diamond coating, the Kryptonite New York Diamond offers superior angle-grinder resistance compared to all other products in this list, including the Litelok models. However, it is significantly heavier (5.2 lb) than the KryptoFlex 710 (1.15 lb) and has smaller internal dimensions that may not fit larger wheels or frames as well as the extended-shackle Litelok X1 Plus.

Litelok X3 Armoured

The Litelok X3 Armoured matches the angle-grinder resistance of the Litelok X1 Plus through its Barronium composite armor but offers a longer reach for versatile fitting around wheels or frames. It is heavier (4.63 lb) than the KryptoFlex 710 and Kryptonite Evolution Mini-7, making it less suitable for daily carrying compared to those lighter alternatives.
