App down loaded on a Samsung Tab A 10.1,
Tacx Bushido smart trainer, wheel on with guessed power output…<5% , NOT!
Stages 4i left hand crank as true power source, set in app.
Recently changed over to the Stages as the Bushido was losing 30/40 watts in real power!
Previos ride was erratic all the way through for power data, but the last ride became smooth just after half way?
Very strange on the spiky switching to smooth. The spiky is pretty intense as well, much higher than my single sided assioma pedals. I am not sure what to say. I don’t have any good ideas. What happens when you just record your bushido?
Yes this is how it should look. So it appears to be your stages power meter causing the spikey-ness. As you can imagine a single sided power meter without any internal smoothing will be more spikey although my single sided pedals are nothing like yours. I think my pedals might have some type of smoothing built in. Other software likely applies more smoothing to it so you might not notice it. Ours has no smoothing.
Ahhhhh, pants…what’s happened now? Next ride was way more spikey and would not follow the WO profile as I had to change my gear and cadence to get close?
If your PM and trainer are both connected it should always use the PM as the power source, unless there is some bug and it connects to one first and sticks to that one. That would explain it. Usually power meters are much more “jumpy” than power from a trainer. I don’t remember but did you try it without your power meter? I always want to blame wheel on trainers but I can’t say that would be the problem here.
Hi Alex,
the majority of the rides have been with the Bishido as the power data source, but 2 issues have become very apparent…
the Busido power output is wildly out, as stated something like 30/40 watts,
when riding a workout the measured output always seemed to be higher than the target and would never equalize.
This was the reason for fitting the Stages to the turbo bike.
The below ride is with just the Busido, first 15 mins I’m changing gears then I ride in the same gear for the remainder. You can see problem 2 as above.
This is interesting/strange. Do you have a bike computer? Can you do a ride like you did but record your stages on bike computer at the same time? I think this large difference between target and actual in Bushido is the source of the problem but not sure why. If you record and send me both files it might help understand.
Sounds fine. Generally it seems something is wrong with your bushido because even if the power meter in the bushido is inaccurate the actual and target should basically be the same. Not this large offset. But this test might help clarify somehow. Also even with this offset and you using stages and power match I am not sure why you would get these spikes.
Looked good and followed the WO as best I can expect, but…the Stages showed an average power for the first 5 min. set as 135 W. With the +35 W being the offset all the way through.
This is the reason I want to have the Stages as the ref. rather than the Bushido.
I’ll try another ride, but making sure I ‘un pair’ the Stages from anything then add it to the App. sources.
