The world’s most cut-proof cycle lock

A student who had his mountain bike stolen has created what he claims is the world's most cut-proof cycle lock.

Felix Ure, a product design undergraduate from Nottingham Trent University's School of Architecture, Design and the Built Environment, created the Hench lock using Kevlar - a high strength fibre material found in body armour - after his Norco Rival bicycle was stolen when he was a school boy.

The 23-year-old will now see his design go on show at Nottingham Trent University's Art and Design Degree Shows Festival between 30 May and 7 June. The festival this year coincides with the celebration of the university's 170 years of art and design heritage.

Felix, originally from Tunbridge Wells in Kent, said: "I know how it feels to have a bike stolen. It can be extremely frustrating, especially when you've worked hard to earn the money to buy it as I did."

"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."

The design centres on the Kevlar being wound through two case-hardened steel chains. The chains and the Kevlar are then enclosed inside a nylon cover.

When a rotary tool is used, such as a cutting disk (see video below), the Kevlar and nylon snag the blade and disable the tool. During testing Felix found that not even an angle grinder, hacksaw or bolt cutters could cut through it easily.

"It's an extremely strong piece of kit and I'm very proud of it," said Felix, who hopes to launch the Hench lock on the open market.

"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."

Felix hopes to find financial backing required to launch the product on the open market and has appealed for funding via The website allows budding entrepreneurs to pitch their ideas to potential backers and receive funds in the form of pledged donations.

Nottingham Trent University senior product design lecturer Luke Harmer, who supervised the project, said: "Felix's bike lock has massive potential and I'm reallykeen to see him take the project further to make it into a commercial success."
