ERG Mode is automatic resistance control. The bike auto-tunes to your personalised target wattage so you only manage cadence (RPM).
When ERG is available
On compatible BLE FTMS bikes with ERG support.
Toggle Enable ERG before joining a class (or in the in-class menu).
ERG is rider-controlled — each rider can enable or disable it independently.
How CicloZone's ERG works
Resistance is auto-tuned per rider, per interval, based on your personalised power zones.
If you make a manual nudge to the resistance during an interval, that change applies to the current interval only.
The next interval automatically resets to the class-defined target — so the class profile is preserved.
When NOT to use ERG
If your bike doesn't support ERG (most Keiser M3i, ICG IC5–IC8 do not).
If you want to manually drive resistance for a free-form workout.
How to enable
On the join screen of the CicloZone app, toggle Enable ERG.
Or, inside a class, open the menu and toggle ERG on / off.
