DIY University found that this braided steel cable provides minimal security compared to rigid D-locks or high-end chain locks due to its vulnerability to common hand tools. While the flexible design allows for versatile use with bikes, grills, and kayaks, it is not as durable or dependable as primary locking mechanisms like padlocks. The double loop configuration enables capturing the frame and wheels simultaneously, but users must accept that this lightweight option serves primarily as a theft deterrent in low-risk environments rather than robust protection against determined attacks.

Strengths
  • — Flexible braided steel cable allows locking in tricky situations or around immovable objects
  • — Versatile design suitable for securing bikes, grills, lawn furniture, kayaks, and sheds
  • — Double loop configuration enables capturing frame and wheels simultaneously
Watch-outs
  • — Provides minimal security compared to rigid locks like D-locks or Hexlox
  • — Cable is not as durable or dependable as the primary lock mechanism itself

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.

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Kryptonite KryptoFlex 410 Double Loop Security Cable

This model is lighter (0.7 lb) and shorter (4 ft) than the KryptoFlex 710 (1.15 lb, 7 ft), offering a more compact option for securing smaller items or tighter spaces. Like the KryptoFlex 710, it provides minimal security compared to rigid U-locks such as the Kryptonite New York Diamond or Litelok X3 Armoured, serving primarily as a theft deterrent rather than robust protection.

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.
