Hi,
How did you get on with the SMB1?
I picked up one of the inxide XS08’s its a spinning bike with magnetic resistance the same as the bodytone (smb1) the controlled resistance is a little odd though when riding in zwift and rouvy doesn’t seem to be able to control the resistance, I found in zwift I can average higher and more stable power out put when setting it to manual controls, using the controlled option the bike seemed to be way too low geared in the flats and too difficult on the hills, EGR mode is different again, that seems to be a better balance.

The Inxide XS08 actually shows up as an SMB1 IN zwift and rouvy, they do look similar as well, just the flywheel difference 22kg bs 24kg really.
