LITELOK Silver

LITELOK Silver

The Brits have outdone themselves with this entry.

The LITELOK is a lovely looking and secure piece of equipment. 

Let's look at it in more detail..

Product Review

The innovative LITELOK has been independently tested and proven to resist all common bike theft tools, with a lightweight, flexible shape that is easier to use and has more securement options than rigid U- or D-shaped locks.

And it's been designed to be so sleek and fashionable that it can even be worn as a stylish, reflective belt.

Two LITELOKs can be looped together for more length, to secure both wheels, or to secure accessories and other items.

It's an incredibly secure, versatile, and even stylish lightweight bike lock.

The LITELOK Silver comes in lengths of 52, 70, or 85 centimeters.

The overall length determines whether you will be able to secure one or both bike wheels, but also determines whether you will be able to wear it around your waist, if you want to. 

At 52 cm length LITELOK weights 1.4 pounds, and is 40% lighter than equivalent U or D locks.

It has a diameter of 7.1 inches, a width of 1.4 inches, and a locking circumference of 20.5 inches. 

The flexible band allows you to use the lock in unusual spaces or with unconventional shapes, giving you lots of ways and places to lock up a bike.

The Litelok Silver has been independently tested against every common bike theft tool, in simulated real-world as well as laboratory conditions.

It has been given a Silver rating by Sold Secure, the UK's leading independent testing association, and a very good 2 star rating from the Netherlands' ART foundation, two of the most respected testing organizations in the world.

The Litelok Silver comes with two keys on a stainless steel cable keyring, a drawstring carry bag, hook and loop straps to carry it on a bike frame, and a wearable kit for wearing it as a belt.

PROS

  • Independently tested and earned a silver rating
  • Flexible shape for versatility and use on lampposts, etc.
  • Lightweight and portable
  • Can be worn as a belt, hung from a bike, or stashed in a bag
  • When worn as a belt, it has a reflective surface for additional security
  • Two can easily be used separately or attached together

CONS

  • It's a medium-security lock, and those in high-risk situations will need a more secure lock

CONCLUSION

For the best lightweight bike security, the Litelok Silver is our top pick for 2021.

It has an impressive Silver rating from Sold Secure, and a 2-star rating from ART, which is a difficult feat for a bike lock that weighs just 1.4 pounds.

The flexible design allows for a wide range of attachments, making it easy to use virtually anywhere, and the material is naturally quiet, without rattling or clanking.

The ability to wear it as a belt is incredibly convenient, and makes it even easier to carry and use.

When worn around the waist, it is so light you almost forget that it is there, and it's both reflective and stylish.

It's simply the best lightweight bike lock available today
