For the most part the Tacx Bushido smart works really well on Zwift. The one persistent problem I seem to be encountering occurs in workout mode, specifically on interval workouts. At medium resistances the erg mode functions well but as the work load increases the resistance encountered seems to become dis-proportionally difficult. It become virtually impossible to pedal.
It appears that others are experiencing this problem? Is Tacx fixing it? Or should I look for a better solution?
