Zwift Hub & Isla Bikes - 7speed

Has anyone had any joy putting on a child’s bike to the KICKR core with the zwift hub? My son is really keen to try his bike on a direct drive turbo but I know technically it states it’s not for a 7 speed

Look for the cassette replacement article on the Wahoo site. It explains which spacer you will need. Should be fine if the bike fits on it.

Or use it with the Cog with an 8 speed chain if 7 is too wide and rubs on it.
