Sold Out
This item is now sold out & unavailable to order. We will leave this page here as a reference to the specification for this model.

Litelok is the worldā€™s lightest, flexible 'Sold Secure Diamond' bike lock.

The "go-to" solution for the highest level of security available for bicycles. Using materials carefully selected for their unique properties, it can withstand sustained attacks from common theft tools to the highest level, including attacks using bolt cutters, crowbars, cable cutters and hacksaws.

LiteLok Core Diamond rated Bicycle Lock

One of the very first locks to obtain the new Diamond rating from Sold Secure, the Litelok Core gets its strength from a multi-layer combination of materials selected specifically for their unique properties.

Sold Secure set the benchmarks for the rating of bicycle and motorcycle locks and their information is relied upon heavily by Insurance companies to calculate their "risk" when deciding on premiums. The quality of your lock can have an effect on the premium you pay.

Four separate layers make up the band of the lock, each one building on and protecting the layer beneath from sustained attacks from a variety of commonly used tools in bicycle theft.

The revised locking assembly uses stainless steel components and high strength, hardened steel casing.

Litelock Core construction

Litelok does more, with less.

Before Litelok launched their "Original" and "Wearable" range, the previous top level "Gold" locks were bulky D-Locks, shackles and large chains. These were all considerably heavier, and not as easily stowed on the bike.

Litelock Core competitors

With the new Litelok Core, not only does it carry the coveted Diamond rating, but its closest competitor is over twice the weight!

As well as class leading security as super light weight, the Litelok Core comes has a multitude of stowage options. It can be packed in pannier bag or rucksack but if you ride without either of these, the built in wearable strap and included mounting straps mean you'll never need to leave home without it!

Diamond rated for a reason

Quite simply the best lock money can buy. I have the 75cms and it's fine for anywhere you'd usually lock a bike. I'm pretty sure even a high-spec power tool would struggle to get through, it's that durable.
