Hi all,
I just set up a Schwinn IC4 spin bike and paired it with my Garmin Venu 4 via Settings > Connectivity > Sensors and Accessories. The devices show as connected, but no data (cadence, speed, distance, etc.) is transmitted from the bike to the watch. I’ve rebooted both devices and tried multiple configuration changes, but nothing resolves the issue. The connection appears active, yet the Indoor Bike activity records no metrics.
As a temporary workaround, I start a Cardio activity and enable Heart Rate Broadcast. That allows my HR to show on the IC4 console but I bought this watch expecting that Indoor Bike mode would pull in metrics from a connected smart bike, especially one as widely used as the IC4.
I’m aware of third-party solutions (e.g., QZ or Zwift) that can bridge this gap, but I don’t want to rely on paid subscriptions or external apps to log basic workout metrics. I’d also prefer not to manually import or edit data after every session.
This issue seems to have affected other Garmin watches in the past. For example, Fenix 8 series users reported a nearly identical pairing failure with the IC4, which was eventually fixed in firmware:

Can someone from Garmin confirm if this is a known bug or firmware limitation with the Venu 4? And if so, whether a fix is planned?
