Ranked #6 in Best Bike Locks

Kryptonite KryptoFlex 410 Double Loop Security Cable

3.0

3 sourcesall derived$18.95as of Oct 2

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

Litelok X3 Armoured

4.0

4 sources$430as of Oct 2

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 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 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.
