Hardware

Works with your smart trainer

zCycle talks to your trainer over Bluetooth FTMS (Fitness Machine Service). If your indoor trainer supports FTMS, zCycle can read power and cadence and control resistance — no USB dongle required on Mac.

Indoor cycling setup with a smart trainer and road bike
Mac connects to your trainer over Bluetooth. iPhone mirrors the ride on the same Wi‑Fi network.
Elite Suito direct-drive smart trainer with road bike mounted

Direct-drive trainers

Your rear wheel comes off. The bike mounts directly to the trainer flywheel for accurate power and ERG control.

e.g. Elite Suito · Wahoo KICKR · Tacx Flux · Saris H3

Wahoo KICKR Rollr wheel-on smart trainer

Wheel-on trainers

Keep your rear wheel on. A roller presses against the tyre and adjusts resistance via Bluetooth.

e.g. Tacx Flow · Elite Nero · Wahoo KICKR Snap

Wahoo KICKR Bike Shift smart indoor training bike

Smart indoor bikes

All-in-one bikes with built-in power meters and controllable resistance — no separate bike required.

e.g. Wahoo KICKR Bike · Tacx Neo Bike · Stages Bike

Wahoo TICKR FIT Bluetooth heart rate monitor

Heart rate monitors

Optional but recommended for zone rides. Any standard Bluetooth LE heart rate strap or armband works.

e.g. Garmin HRM-Pro · Polar H10 · Wahoo TICKR

Tested with Elite Suito T

FTMS power, cadence, speed, ERG mode, and grade simulation. Most modern FTMS trainers should work the same way.
