The BikeRegister Permanent Marking Kit is the perfect way to protect your bike from thieves. With this kit you will join the UK's national, police approved, bicycle marking and registration scheme. This kit enables you to mark your bike and add your details to the BikeRegister national database. The visible warning label reduces the risk of theft by warning thieves that your bike is registered, but if the worst should happen, every police force in the UK uses the BikeRegister database to search for stolen and recovered bikes, immensely improving your chances of getting your bike back.
This kit protects your bike by permanently and chemically etching your unique BikeRegister ID into the coating of your bike's frame. The etching is visible blue, leaving a neat unique mark which does not affect the frame’s integrity.
