The files below explain a national database – Bikeregister.com – on which you can detail your bike and its bits.
Entering your cycle's unique features makes it easier to identify if stolen, and checking a second-hand machine before buying means you can avoid profiting from someone else's misfortune.
The site is approved by the Police – including PC Simon Daley – and is free.
