Probably been covered many times before - I’m 50yo male and got back into road riding after a 20 year layoff !!! Any way - I’m fit - I surf, train at the gym , run etc - decided for dust of my Cannondale R1000 - upgraded the group set, new wheels etc and started back doing 150km - 200km per week - then lock down! So I dust off my Jetblack Fluid trainer and discover Zwift - wow - great fun. Using a dumb trainer I bought a speed and cadence sensor - and at first my watts were low…real low - then played around with trainer type and got sort of close but despite riding hard - I could hang on in group rides after 15 mins or so…I then upgraded to a 4iiii Power meter - boom! I can’t keep it below 250watts in first gear!!! My FTP has gone through the roof…is this normal for Zwift? Seems like my “low effort” power reads very high 50-100 watts - yet when Inturn on the power - possibly still under reading?
Have you done a Zero Offset (Calibration) on the power meter: https://4iiii.zendesk.com/hc/en-us/articles/360028149551-How-do-I-Zero-Offset-Calibrate-My-Powermeter-
I did that when I first put it on - I’ll do this again ibefore my next ride - will see if it makes a difference
So I lashed out and bought a new Waho Kickr Core…all sorted! Much more realistic and accurate power readings!
Something is not right here. I have been using a 4iiii power meter for years without any issues, and I have never heard of any issues like the one you are reporting.
Also, how did you get your hands on a Kickr Core so fast?
The 4iiii Powermeter is working - problem was my fluid trainer - it’s stuffed!!! I called my local bike store and almost fell off my chair when they told me they had one last Kickr in stock!! I went straight down and picked it up! Fluke.
