What follows is a lesson in writing down and recording any details you can of your bike, especially serial numbers.
A year ago, my Carbon 456 was stolen, alongside a KTM 200 motorcycle. The 456 was built up from a on-off paint job that On One did as a sample and there were other oddities, like DT Swiss E2200 hubs laced to Mavic XC717 rims, that made it a very individual bike. I thought it likely that, at some point, it might come up for sale somewhere.
I set up an eBay search for the bike, forks, KTM, KTM frame, E2200, etc. Anything I could to find the bike or motorbike if they were listed. And last week the 456 was listed. Police were called and went round to investigate.
But I've just spent a very stressy week, trying to prove beyond reasonable doubt that the bike was mine. The police, faced with a current and an original owner, both saying they own the bike, have to prove beyond doubt, one way or another, who's right. It took a 5 page document listing full specs, blown up pics of sections of the bike and a statement from On One that they had only made one frame in that colour, plus a DC who knew bikes and bike bits. But the bike is now rightfully mine again.
All I really needed was the frame number, which I'd never recorded.
So, please, to save yourself a lot of anguish, go out to your bikes tonight with a camera and a notepad and record frame numbers, serial numbers of all the components (forks usually have serial numbers, too) and any quirks that make your bike, your bike.
And maybe even get one of these for each bike.
