Kryptonite New York Diamond
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.

LITELOK X1 PLUS
6 sources2 derived$260as of Oct 2

Bikerumor noted that the Litelok X1 Plus adds nearly 60mm of length to the popular X1 model, creating a lock specifically designed for bulky e-bikes and cargo bikes while retaining its angle-grinder-resistant Barronium armor. Thebestbikelock found that this ceramic composite layer turns the tables on thieves by rapidly wearing down cutting discs, making it one of the most practical high-security options available despite not being the absolute thickest in class. Cyclingelectric highlighted the lock's ease of use and secure mounting system as key daily benefits, though they cautioned that its 1.7kg weight is a factor for commuters who prefer to carry their gear. While biketoeverything praised the extended reach for locking multiple bikes or securing helmets, reviewers consistently noted that the premium cost and added heft are trade-offs for this specific geometry.

Strengths
  • — Barronium composite armor layer actively wears down angle grinder discs, significantly increasing attack time compared to standard U-locks.
  • — Sold Secure Diamond and ART 4 rated for the highest levels of pick, drill, and bolt-cutter resistance.
  • — Extended shackle length (255mm) accommodates larger e-bike frames, cargo bikes, and allows locking two bicycles together.
Watch-outs
  • — Weight of approximately 1.9kg (4.2lbs) is heavier than standard U-locks, making it less ideal for carrying in a backpack.
  • — The lock is heavy and can be difficult to carry in a backpack.

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 X1 PLUS

The Litelok X1 Plus features Barronium composite armor that actively wears down angle grinder discs, providing better power-tool resistance than the Kryptonite New York Diamond or KryptoLok. It also offers an extended shackle length (60mm longer than standard) to accommodate e-bikes and cargo bikes, unlike the tighter dimensions of the Kryptonite Evolution Mini-7 or Kryptonite KryptoLok.
