If your bike doesn't appear in the device list, work through these steps in order.
First, one thing that saves a lot of time: CicloZone connects over Bluetooth (BLE) only. An ANT+-only bike will never appear in the list, no matter what you try, and neither will a closed-ecosystem bike such as Technogym, which has Bluetooth but doesn't broadcast its data for other apps to read. If that's your bike, none of the steps below will help — see "Will my specific bike model work with CicloZone?"
Quick checks
Is the bike powered on?
Some bikes need a generator wake-up — pedal briefly to power up the Bluetooth module, then refresh the list.
For battery-powered cranks (e.g. CicloZone Power Crank), check the CR2032 battery isn't flat.
Is your phone's Bluetooth turned on?
Open your phone Settings → Bluetooth → ensure it's ON.
Has the CicloZone app been granted Bluetooth permission?
iOS: Settings → CicloZone → Bluetooth = ON.
Android: Settings → Apps → CicloZone → Permissions → Nearby devices / Bluetooth = Allowed.
In the app
Pull down on the Bluetooth device list to refresh.
Tap the bike whose number is shown on its phone tray.
The app shows devices sorted by proximity — your bike should be at the top.
Still not seeing it?
Is another phone already paired to this bike? Only unpaired bikes are shown to you. Have the other rider end their session.
Try moving closer to the bike (BLE has a short range, ~10 m clear).
Restart your phone's Bluetooth (turn off, wait 10 s, turn on).
Close and reopen the CicloZone app.
Try a different bike — this tells you whether the problem is the bike or your phone.
If nothing works — ask us
If you've worked through all of the above and your bike still doesn't appear, ask in the chat and include:
Your bike make and model.
Your phone model and OS version.
Whether the same bike appears for other riders, and whether other bikes appear for you.
Your studio name.
Those answers usually tell us straight away whether it's the bike, the phone, or a compatibility limit. For old or non-Bluetooth bikes, you may need a CicloZone Power Crank or a Bluetooth RPM sensor — see "Which bikes are compatible with CicloZone?"
