Bicycode is your bike's tattoo, a unique number engraved on the frame, a distinctive sign that says "This bike is mine, and no touching!" 🚴♂️ Except that unlike a tattoo, this marking isn't there for show (I'm not talking about yours of course 😜), but for safety.
Engraved on your frame, often on the bottom bracket side, this number registers in a national file. You're thinking "So what?" Well, in the event of theft, it's this number that makes it possible to find your two-wheeler and contact you for a happy restitution meeting. 🕵️♂️
