Don’t hate me because I’m using a spin bike. I put the Wahoo cadence device on my shoe and what the display on my spin bike matches exactly as what Zwift is telling me. However, when I attach the speed sensor to the spin fly wheel (at the smallest/shortest rotation near the bolt) I get different readings. Zwift is about 4 to 5 MPH faster than what my spin bike reads.
Just for clarification: Peloton bike. And yes, I know my wattage won’t be right. I’m doing this for fun and as an experiment to see what extra use I can get out of my wife’s peloton bike before deciding to invest in a trainer setup.
p.s. maybe it doesn’t matter. It’s just for fun, for now. But I was hoping to get the MPH to match up like the cadence.
