I am trying to get my mountqinbike going on zwift, but I seem to be having an issue with inaccurate wattage. I have a 29’er on my Saris Fluid 2 trainer and I am using the saris speed sensor. I set my tire size to 700x32cc but can’t seem to get my wattage accurate. Any help?
What do you use to compare power?
Did you pair as a speed sensor with the correct trainer?
Hi Gerrie.
It doesn’t matter how hard I peddle, my watts stay under 65. Which does not make any sense. Using my road bike previously with my speed sensor it was very accurate. And Yes I did pair it correctly with the correct trainer.
My guess is that the gearing on the MTB is the limiting factor.
wattage not going to be “accurate” without some kind of power meter anyway :3
doubt it’s gearing, 65w is literally nothing, no reason you can’t hit 1000w in hardest gear on a MTB :3
I found that speed sensors can be very inaccurate on a mountain bike because of the increased clearance between the wheel and frame.
The hub mounted ones probably work better.
Accuracy is always questionable with all speed sensors.
