Why the serial matters
A repaint changes the colour. The stamped frame number doesn't.
Colour, decals and even the wheels can be swapped in an afternoon. The serial pressed into the bottom bracket is what a thief has to grind off — and almost nobody does. Recorded here, it is the string that settles an argument with a seller, a shop or an officer.
Registries alone
A registry remembers. It doesn't go looking.
529 Garage and Bike Index hold your serial and answer a query — when a buyer, a shop or an officer thinks to run one. That leaves the record sitting still. FoundWall puts the same record where people already look: a public notice on the board your neighbourhood can search.
529 Garage free registry
Stops at the registry
Stores your serial and photos. A match needs a human to run a check against it.
Bike Index free registry
Stops at the registry
A searchable record of stolen bikes. Powerful when queried, silent until then.
FoundWall registry + public notice
Puts it where a finder looks
We keep the record, publish a searchable notice against a coarse area, and give whoever finds the bike a private way to reach you — with the serial held back as proof.
Do this before it's gone
Find your frame serial in two minutes.
It's a short string — usually 6 to 10 characters — stamped into the metal. Flip the bike over and read it off the bottom bracket, the round shell where the pedal cranks meet the frame. Photograph it straight-on, in good light, and keep the photo.
01
Bottom bracket first.Underside of the frame between the pedals — the most common spot on road, gravel and mountain bikes.
02
Then the head tube or rear dropout.If the bracket is blank, check the front tube under the handlebars, or the flat tabs where the rear wheel bolts on.
03
Record every character exactly.Zeros vs. O's, I's vs. 1's. A single wrong digit is a serial that won't match a listing.
