Hi there, just stumbled upon the thread; happy to have found some people with similar questions.
Amazon Germany redirected me to Spofact/Ulm (spofact.de) for German support which responded quite fast, but they did not acknowledge any problem so far …
My (limited) experience so far is
- Zwift does connect as a power source + cadence (not as controllable). (controllable shouldnt make too much sense as the Schwinn IC8 is not a smart trainer?!)
- speed / distance readings from the console are looking generally too high - very slow riding (30 rpm) on light level 35 already results ~ 24 km/h. with 60 rpm on level 35 ~ 36 km/h.
- Zwift readings on level 35 / 60 rpm: ~210 watts (directly shown in the bluetooth/sensor screen). Speed: ~35-38 (test on sections of mostly flat volcano track).
- Took the measurements from another bike. Same results.
