Hey just looking for advice I’ve been training for an Ironman with the Schwinn spin bike at the gym and it seems like the power numbers read about 10-20 watts high. Just wondering if anyone has more hard data on the power accuracy of these bikes compared to real “accurate” pms. I put some of my workout numbers etc on IG at @kclarkzeroto300fitness thanks in advance for any help/advice!!-KEVIN
These use either a Stages power meter (brick on left side crank arm) or a flywheel rpm sensor (like a lot of highend trainers do). The stages units are wildly inaccurate in my experience bike to bike, but consistent-ish. The rpm sensor as-implemented is probably wrong but consistent.
