Zwift engineers please “support” the indoor bike: Schwinn IC4 - Bowflex C6 - Schwinn IC8 (European Version). They are all the same bike under different marketing names. Nautilus (the parent company) is advertising that they are compatible with Zwift on their websites, but the watt readings are way too high. (See the many posts on this on your forums.) Either the power curve is wrong on the bike console or the power curve is wrong in Zwift.
Nautilus should not advertise that it is compatible with Zwift. Power meter pedals are required to make the bike accurate enough for use. Many cycling novices are buying the bike(s) having no idea what their FTP is and not suspecting that they are cheating until they get a few weeks into it.
The bike also BLE links as “controllable” by default and it is not. At minimum please reach out to Nautilus to remove advertising that it works with Zwift until they comply with your protocols for accuracy.
