Serial Number Database

The question often arises; "When was my bike made?"
I'd like to tell you, but I can't. I can guess, but I don't know for sure. The only way to really know is to check the serial number (found stamped on the underside of the bottom bracket); and then you have to know the code.

I heard a guy on had set up a database of numbers to decode the system. It's simple: by gathering a large sample of serial numbers (and other information) you can pick enough clues out of the pile to crack the code. But I wasn't able to contact him, so I had to start my own database.

So far I have over 60 serial numbers. Most people I meet on the street are actually very forthcoming when they find out what I'm doing. I've also gathered any numbers I can find online. My little database, though patchy, is growing and starting to reveal patterns. When I have a good guess, I'll post up the code so anyone can find when their bike was made.

If you have a Sekine, I ask that you kindly email me ( rodoftheflies ) no spam, please ( ) the serial number and as many details about the bike as you have (every owner should know the serial number of their bicycle, anyway). I won't post this information online (but you can, if you want- comments below!). A clear photograph is best for reference (and your own insurance). Good additional information to include: type of headbadge, any frame decals, type of frame, style of dropouts, paint and chrome, components and their date codes, the more details the better.

And T-Mar, if you're out there, I'd love to compare numbers.


  1. Hey I'm very familiar with aspects of the Sekine project. Ossie Mellon was the person given the liquidation contract to dispose of the assets of the company. He lives in Rosser just outside of Winnipeg, he is a fountain of useless information on the company that professed to be the builders of the finest bikes. They did make one model I wish I had of kept there was only three ever made....dam hindsight. any way if your interested I'll email you his phone number.

  2. I'm always interested in hearing more about Sekine Canada from people with first-hand experience. The name Ossie Mellon rings a bell, and I would like to hear more from him if he's interested. Please forward any information or contact details, rodoftheflies @
