A student from Nottingham Trent University has made what he claims is ‘the world’s most cut-proof cycle lock‘.


Felix Ure, a product design undergraduate, had his mountain bike stolen as a boy and has now created the Hench lock – a security device that uses high-strength fibre material Kevlar.

The design involves the Kevlar being wound through two case-hardened steel chains. The chains are then covered with nylon.

Felix, originally from Tunbridge Wells in Kent, said: “I know how it feels to have a bike stolen… It’s really important that a bike lock can last long enough for a thief to be deterred. I wanted to design something which could help people avoid having to go through what I did.”

A video shows the 23-year-old trying to destroy his bike lock with angle grinders, bolt cutters and more.

“It’s an extremely strong piece of kit and I’m very proud of it,” said Felix, who hopes to gain financial backing for the product via

“Not only does it cause problems for most cutting tools, it’s also very easy to transport as it is flexible and can be wrapped around and secured to a bicycle cross bar,” he explained.


Felix’s design will now go on show at Nottingham Trent University’s Art and Design Degree Shows Festival between 30 May and 7 June.
