Kryptonite stands behind its products by providing an Anti-Theft Protection Offer on specific locks. Created by Kryptonite in 1978, the Anti-Theft Protection Offer is a program that reimburses registered customers for a specific monetary amount in the event their bicycle/motorcycle is stolen due to the opening or breaking of the lock by force. ATPO coverage is not bicycle insurance and there is no affiliation with an insurance company. The offer is administered by Kryptonite. Find out more here

Sold Secure Explained

Sold Secure is an independent, impartial and non-profit testing facility, owned by the UK’s Master Locksmiths Association. They put locks through a variety of tests and assign a security level to them to make it easier to compare between different locks and brands. Tests include lock picking, lock manipulation, drilling and cutting, bolt croppers and other typical attack techniques.

They currently have four main categories of security level for bicycles: Diamond, Gold, Silver and Bronze:

A Sold Secure rating means a bike lock has gone through a series of tests to determine its strength and suitability. Without a Sold Secure certification you cannot ultimately be assured that the lock has been tested effectively and therefore how much protection it will offer your bike.

It’s also worth noting that many bicycle insurance companies, such as Pedalsure, dictate that a Sold Secure rated lock must be used for any insurance claim to be valid. They will also often specify the Sold Secure rating depending on the value of your bike.

You can also be assured that Sold Secure’s testing methods are always up to date. They work closely with the UK police and Insurance companies to ensure they are aware of any new bike theft attack methods and consider these in their testing.
