Planning output only; no application code yet.
Key findings driving the design:
- The Bryton Rider 650 has on-device Wi-Fi (Main Menu -> Data Sync) and
uploads to Bryton's cloud with no phone and no Bryton Active app. Paired
with the reverse-engineered Bryton cloud API — which returns the original
unmodified FIT bytes — this makes ride sync fully hands-off, and higher
fidelity than the current Strava route (Strava's API cannot return the
original file, only smoothed streams).
- Build fresh rather than forking Endurain or FitTrackee; borrow Endurain's
gear/component structure and strava-gear's retroactive time-ranged wear
computation.
- PWA rather than a native iOS app: iOS 16.4+ gives home-screen PWAs real
push notifications, which was the only thing that used to force native.

bike-app
A self-hosted cycling app: syncs rides from a Bryton Rider 650, tracks mileage like Strava, and adds a spare-parts inventory and a maintenance record with mileage-milestone reminders.
Status: planning complete, no code written yet.
Why
Today the Rider 650 syncs over Bluetooth to the Bryton Active phone app, which forwards to Strava — but Active has no background sync, so you have to remember to open the app. Research found a better path that removes the phone entirely:
ride ends -> Rider 650 joins home Wi-Fi (Main Menu -> Data Sync)
-> uploads to Bryton cloud
-> this app's poller fetches the ORIGINAL FIT file
-> rides, wear tracking, and push reminders
That's also higher fidelity than the current route — Strava's API can only ever return smoothed streams, never the original file.

Planned stack
Python 3.12 / FastAPI / SQLAlchemy async / PostgreSQL 16 + PostGIS, procrastinate for jobs,
SvelteKit static SPA as an installable PWA, MapLibre GL, all behind Caddy in Docker Compose.
Source control and CI in self-hosted Gitea with an act_runner on the same box.
Four containers in v1, under 2GB RAM.
Next steps
- Verify on the Rider 650: does
Main Menu -> Data Syncupload automatically on joining Wi-Fi, or only on manual trigger? This determines how completely the phone leaves the loop. - Plug the 650 in over USB and
ls -Rthe mounted volume to confirm the real.fitpath (documented asBryton/Activities/, but worth confirming). - Grab a real
.fitfile from it and run it throughfitdecode— Bryton's encoder is not Garmin's, and the schema should be checked against reality before it's written. - Then Phase 0: scaffolding and CI (see the roadmap in
docs/PLAN.md).
