Sold secure explained

Sold Secure is a unique test laboratory with its own collection of 30 + test standards for many different kinds of products. Sold Secure uses a mixture of repeatable and measurable testing and combines this with human intervention testing to replicate what thieves are doing in the real world.


Sold Secure has two levels of Motorcycle Security approval, Gold and Diamond. It also has two levels of motor scooter security, Silver and Gold.

Some test houses will utilise testing procedures which are “laboratory based only” and focus more on a “materials testing” approach, something that is measured and repeatable.

Sold Secure testing procedures are developed and constantly updated using the latest information from the Police, Secure by Design and leading Auto insurers. The tests are designed to accurately simulate real- world attacks on motorcycle locks, utilising the latest techniques employed by thieves.

General Classification.

Sold Secure has product specific standards for example Motorcycle Gold is a very different standard to Pedal Cycle Gold with much heavier tools being used on the former. However, the following ethic forms the basis of how Sold Secure standards are written.

Bronze – Products offering theft resistance against simple tools concealed about the person (aimed at preventing opportunistic attacks)

Silver – Products offering theft resistance against a more determined attack with a higher level of tools.

Gold – Products offering the highest level of theft resistance which is aimed at preventing dedicated attacks.

Diamond –  Products offering the highest level of resistance which is aimed at preventing dedicated attacks but usually with additional tools that are added to Gold level following changes in crime trends.

So, how does it work?

Each product is firstly “bench assessed”. This involves dismantling the product, assessing what materials it is constructed from, how it is put together and, more importantly, finding potential areas of weakness to attack.

The testing then moves into Sold Secures state-of-the-art testing facility where the engineer will proceed with the physical attack tests.

Silver motor scooter –  Products offering theft resistance against an enhanced tool list (aimed at preventing more determined attacks) for a period of no less than 3 minutes.

Gold Motor scooter  Products offering theft resistance against the full tool list (aimed at preventing dedicated attacks) for a period of no less than 5 minutes.

Gold motorcycle accreditation – The product must be able to withstand an attack lasting 5 minutes with multiple attack methods being applied following assessment.

Diamond motorcycle accreditation – as the gold standard but with the addition of an added angle grinder attack test.

The list of tools and methods available to the tester are decided upon using the latest information from Police, Insurers and even reformed thieves. Then, having assessed the weak points of a system the tester will choose a range of tools and attack methods from their arsenal to ensure the best possible chance of "system failure" ensuring that Sold Secure is the most stringent test possible to date.

Dependant on the level of accreditation being sought, this list might include but is not limited to:


Concealable hand tools (screwdrivers, chisels, picks, shims, cutters etc)

Hacksaws and drills with various blades/bits

Pry / wrecking bars

Club and sledge hammers

Bolt Croppers various sizes

Splitters / Separators

Freezing agents

Angle Grinder (Diamond test only)

No product can give you a 100% guarantee of security but choosing to fit a product that has Sold Secure certification should give you the peace of mind that you are doing your best to dissuade and combat thieves. What is more, providing that you fit the product correctly in a suitable environment, you can be confident that your precious bike has a much better chance of still being there in the morning.

Milenco Security ratings explained

Milenco also apply our own security ratings to our products. These are simply to enable you to understand how "secure" a product is within the parameters of our entire range.

For example; the Coleraine 9mm chain and lock has a Milenco rating of 13 which indicates that it won't be as secure or strong as the Dundrod 14mm chain with a rating of 25. 

However, it is worth remembering that factors other than "security level" will influence your product choice. Weight, cost, number of bikes, environment etc should also be taken into account.

We offer a Lifetime guarantee on our locks that covers normal use and the correct care.

This warranty covers the functional operation of the product and the mechanical integrity of the lock itself and is governed by fair and normal use.
