Power meter on spin bike

I’ve been using Zwift on a spin bike with speed and cadence sensor for a while and I tend to show about 1.5 to 2x the watts on Zwift as the bike reports on its computer. Would adding a power meter instead of a speed/cadence sensor on a spin bike be more accurate or will it just be way off no matter what because it’s a spin bike? Has anyone had experience with a power meter on a spin bike?

I’ve gotten pretty good at modulating climbs with resistance and have wheel size/selected trainer dialed in as best I can but my watts are still too high. My speed is also too high so my distance is off. I would like to have it dialed in better so I can do cycling challenges and group rides. Would a power meter be more accurate?

Yes, I understand an indoor bike is not compatible with Zwift but I needed something quiet.


If you can add power meter pedals or a power meter crank (so if your spin bike can take those) then it will likely be a lot more accurate, yes.
