Let’s cut right to the chase… yes, I opened up my Schwinn 220 and installed the Wahoo speed censor in the middle of the flywheel. Honestly, it’s seems pretty accurate so far, but I do have some questions.
So while I was riding on the California cicuit, my RPMs were perfectly accurate, my speed was accurate as long as the ground was flat, and my distance was within 10-15% of what my bike’s reading was. I’d say that’s an honest start!
However, my watts were registering at a consistence 380-400! I know that’s completely inaccurate, but I’m not quite understanding why I’m getting that reading. With the other data being quite accurate overall, why is it that my zPower and wattage is so dang high? I’d love to know more about this gauge and how I might be able to adjust this.
