What is FTMS and which trainers support it?
FTMS (Fitness Machine Service) is a standard Bluetooth protocol for indoor bikes and smart trainers. RitmoSync connects over FTMS to read power, cadence, and speed — then shows live FTP zones and structured workouts. Not every bike that says “app compatible” actually broadcasts FTMS power.
What FTMS means for RitmoSync
| Term | What you get |
|---|---|
| Full FTMS | Power, cadence, and speed over Bluetooth — best match for zones and intervals |
| Partial FTMS | Often cadence only; power may be missing or estimated — zones won’t be reliable |
| Smart trainer | Mount your outdoor bike (direct-drive or wheel-on) |
| Smart bike | All-in-one indoor bike with built-in power measurement |
RitmoSync needs Chrome or Edge on desktop (Web Bluetooth) or the Mac app (Apple Silicon). Pair from inside the app — not from macOS Bluetooth settings.
Trainers that usually work (Tier A)
Native FTMS smart trainers are the most reliable setup. Keep firmware updated via the manufacturer app.
- Wahoo — KICKR, KICKR CORE, KICKR MOVE, KICKR SNAP, KICKR ROLLR (2020+ firmware)
- Garmin / Tacx — NEO 2T, FLUX 2, FLUX S, Flow Smart, Vortex Smart
- Elite — Direto, Suito, Drivo 2, Zumo, Tuo
- Saris — H3, H2, M2 Smart
- JetBlack — Victory, Volt (popular in Australia)
- Van Rysel / Decathlon — D100 (strong value pick in US, EU, and AU)
- Zwift Hub — built for FTMS
- Magene — T300, T100
Smart bikes that usually work
- Wahoo — KICKR BIKE, KICKR BIKE SHIFT, KICKR BIKE PRO
- Garmin / Tacx — NEO Bike Plus; NEO Bike Smart needs firmware v4.5.0+ for FTMS
- Stages — SB20 Smart Bike
- Keiser — M3i series (enable Bluetooth on the console)
- Wattbike — Atom, AtomX
- TrueKinetix — TrueBike
What to avoid for RitmoSync
These ecosystems typically use proprietary Bluetooth — they won’t appear in RitmoSync’s device picker:
- Peloton Bike / Bike+
- Most Echelon, NordicTrack, and ProForm (iFit) bikes
- Budget spin bikes that only list “cadence compatible” without FTMS power
A bike that “works with Zwift” through a bridge app like QZ may still fail in RitmoSync. See our compatibility troubleshooting guide for details.
Before you buy Pro
RitmoSync is in beta. The free tier lets you validate pairing risk-free — see our step-by-step FTMS test. Pro ($39.90 one-time) unlocks saved history, custom programs, and FIT export.
- Update trainer firmware (Wahoo, Tacx Training, Elite, JetBlack, etc.)
- Quit Zwift, Wahoo, and other trainer apps — only one Bluetooth client on many devices
- Open RitmoSync web app in Chrome or Edge
- Connect from the RitmoSync menu and pedal to verify live watts
