Bikes don't tell you when parts are wearing out — Geer does. Connect Strava, add your components (chain, cassette, brake pads...), and get alerts before things fail. No app store needed — it's a PWA that works on any device. Free to start, Pro for €2/mo. Built in the EU, privacy-first, no ads.

Hey PH! I'm Ron, one of the founders of Geer. We built this because we got tired of guessing when our components (e.g. chain or cassette) was due for a swap — and spreadsheets weren't cutting it. Geer syncs with Strava, tracks wear on every component, and pings you before things break. It's a PWA so there's no app store install needed. Would love your feedback — what bike maintenance pain points do you have? 🚴

Comment highlights

really smart approach connecting to Strava data. most cyclists track rides anyway so using that existing data stream makes total sense. curious how accurate the wear predictions are in practice - are you factoring in riding conditions, power data, or just distance/time?
