Classic Bicycle Serial Numbers

A growing, moderated archive of serial numbers for classic and vintage lightweight bicycles — built from records shared by owners and from Ebykr research. Look one up, browse by maker, or add yours.

Enter a full or partial serial number, choose a maker, or both. Serials match however they are stamped — spacing and punctuation do not matter.

23 serials from 16 makers

Log a serial number

It takes under a minute. Only a serial number and a maker are required; anything else you add makes the record stronger. Every entry is reviewed before it is published.

Add more detail (optional)

History, how you came by it, anything notable. Please do not enter another living person’s name without their permission — describe former owners generally, for example “a French collector”.

Paste links to photos of the bike and, ideally, a close-up of the serial stamping (your own site, Flickr, Google Photos and the like), one per line.

This is the only name shown publicly. Enter a first name, initials, a username, or leave it as “private collection”. Your real name and email are never published.

Only if you would like us to be able to follow up. It is never published.

Your IP address is recorded privately for moderation. You do not need an account to log a serial.
