...a rather clever design that uses a flexible multi-layer material that’s been christened ‘Boaflexicore’. Having many layers means that the lock is able to withstand attack from pretty much all the tools your average [ thief ] might bring to bear yet still wrap round things unlike a clunky U-lock.

I really enjoyed using the LITELOK. It’s a lot tougher than it looks. It gives me loads more locking options when the bike racks are full. It’s really easy to carry. And it’s incredibly light for a high security lock

I am Professor Neil Barron, the founder and inventor of Litelok, a former Aeronautical Engineer (Rolls-Royce aero engines), designer and keen cyclist. After having several bicycles stolen on the streets of London, and fed up with having to carry around heavy bike locks, I thought there must be a way to create a high-security, lightweight bike lock. Many cyclists I spoke to agreed that it didn’t seem right that as bicycles were getting lighter and lighter, secure bike locks were getting heavier and heavier. 

After years of research, development and testing, my team and I created and patented a new composite material called Boaflexicore. It is made of layers of innovative materials that keep Liteloks lightweight but difficult to cut or break. Each layer provides additional security, meaning it can withstand sustained attack from tools like cable cutters, bolt croppers, crowbars and hacksaws. The locking mechanism is made from hardened steel and is very difficult to pick. This is also patented. 

In March 2015 we ran a crowdfunding campaign on Kickstarter, raising over £232,000. This helped turn the idea into a reality. I am incredibly thankful to our Kickstarter backers without whom we wouldn’t be here. We have built on this early success, now offering Liteloks all over the world, from our HQ in Wales, UK. Litelok Gold won Best Cycling Innovation at the 2016 London Cycling Campaign awards and was declared the Best Bike Lockin the foldable category by Cycling Plus in 2017. 

I am delighted to announce that as of August 2017 we have secured a seven figure co-investment from Finance Wales and a syndicate of Business Angels. Supplemented by other early stage funding which came from the European Regional Development Fund, through the SMARTCymru programme, this investment will allow us to invest in high-tech manufacturing in South Wales, as well as sales, marketing and product development. 

I believe passionately in Litelok. If you have any questions, you can contact us at [email protected], we are happy to help!
