WHO WE ARE

We were sickof keeping a notebook.

HOROTAG was born from a simple observation. When a serious rider resells their bike, they always end up pulling out a shoebox full of crumpled garage receipts and pencilled notes in a torn notebook, then try to explain the servicing from memory. The buyer just has to take their word for it. And with no proof, it's the buyer who sets the price.
THE STORY

Why we built it.

The problem isn't that riders lie. It's that a paper log proves nothing: it gets lost, filled in after the fact, rewritten. And an hour meter can be reset to zero. The upshot: even a spotlessly maintained bike gets haggled down like a shady one.

We started HOROTAG to replace crumpled receipts and tampered meters with mathematical proof. Today we offer three devices doing the same underlying job, sealing an honest logbook: HOROTAG RUUVI (Bluetooth sync, €129), HOROTAG GPS (4G cellular tracker + anti-theft, for every rider, €299) and HOROTAG ULTIMATE GPS (4G cellular + detailed GPS track + alert when the bike sets off, road as well as off-road, €399). Only RUUVI counts hours and seals them: ULTIMATE GPS estimates hours and mileage from trips, and GPS estimates hours from the length of your rides, with no mileage. The sealed service log itself is identical across all three. No trust required.

At resale, one QR code to scan is all it takes for a buyer to see everything: with no way to cheat and no way for you to fudge the numbers. It's shorter than a lie, simpler than an argument, and infinitely more credible than a box of receipts.

PRINCIPLES

How we work.

Software and data in France

The HOROTAG RUUVI firmware, the app and our servers are developed and run in the Yvelines. The devices are manufactured by Ruuvi Innovations Oy (Finland) and Digital Matter; we program, test and pack them in France. Support answers you in French, by a real human.

Strict GDPR

No trackers, no ads, no reselling your data. We make our living from the device, not from you. Our servers never leave the EU.

Honest mechanic

No jargon, no marketing-speak. When we don't know, we say so. When we get it wrong, we fix it publicly.

The log first

Credibility at resale is our compass. Every feature has to serve it: otherwise it doesn't make it into the app.

WHO WE ARE

One person who rides too.
