Hi!
First i would like to thanks you for your great app!
Unfortunately, after lot of hours trying it, i am still not able to have “ERG” mode working. When doing a workout, resistance is not controlled automatically according to the workout. The only way to switch resistance is to manually change it in “resistance” mode.
I have tried with iOS and android, for several workout, and nothing work.
Am i missing anythink? Any option to set?
My bike is a Bodytone model SMB1.
My best,
Thomas
Hi Thomas, thanks!!! I can’t read all of this thread below (in French it looks like) but it looks like your bike does not work in ERG mode in Zwift either so that would be a problem with the bike. We have slope mode (you can click on slope and up down to see if that works, sounds like it does in zwift) but you still have to control your power manually.
Hi Alex,
Thanks a lot for your support and quick answer! I tried and it seems that slope mode with automatic (or even manual) variation does not work.
Only resistance mode with manual variation in the app is working and give instruction for resistance change to my equipment.
Is there a way to directly set-up a resistance target in % for each zone when creating a workout ? I think this would allow me to have automatic resistance variation for “dumb” equipment like mine :). Sorry, but I tried and could not figure out how to proceed.
Thanks a lot,
Thomas
Oh interesting. No currently we only have ERG, Slope and HR, there is not automatic programming of resistance mode and since no one has previously asked for this it seems unlikely we will do it any time soon. It’s very rare that resistance mode works and slope or ERG does not. I have heard of it in a couple other bikes over the years. One thing people do is they like to use slope mode and shift gears manually when trying to do a workout. Eventually I would like to support virtual gears that you could push a button on something like a zwift click or other bluetooth device and change gears. This would add more resistance manually. That is something we are willing to explore sooner, but I still can’t say when it it’s more likely months or years away but still likely sooner than programable resistance mode unless many more requests come in for this. We can turn this post into a feature request.
Thanks a lot Alex! So I guess I will have to be patient:)
Alex,
Thanks for the app & all the advice. I’m in the midst of transitioning from a Kurt Kinetic (served me well) to a Jetblack Victory. I had been doing a lot of ReHIT on the Kurt, simply because I’m pressed for time. So, my transition to smart trainer was effectively a campaign to replicate the 2-3 min rests & 15-25 sec all-out sprints. Others have noted that erg mode is not well-suited to this activity pattern, and I can confirm that. Although otherwise rather sparse, the Jetblack app has a specific resistance mode, and the resistance level can be set manually. I set the resistance to a low, constant level, used another app to set the ReHIT timing and recorded the 9+ min session.
The experiment turned out pretty well; the power profiles looked pretty square with little over/undershoot at the transitions. So, on behalf of any other ReHIT fans out there, I want to support the Tomtom33520 suggestion for a programmable resistance mode.
Could you use slope mode?

Dave,
In fact, that was the first mode I tried after I realized that only TrainerRoad had a fluid trainer mode and it cost a lot more than TrainerDay. I figured slope mode in TrainerDay was, at its base, just another way to set resistance. I set the ReHIT routine up in TrainerDay with a constant slope for all intervals & rests. The sprint intervals showed a lot of over/undershoot at the transitions but not as dramatic as with erg mode, which I tried next. Relatively speaking, lots of lag with erg mode for these short intervals, as others have noted. I wanted to improve on the slope result which led to resistance mode setting in the Jetblack app and the outcome I described earlier. Need to be careful here in drawing conclusions; the way TrainerDay sets resistance via slope may differ from the way the Jetblack app sets resistance directly in the app. The bottom line is that slope mode can be used, but one needs mindful pedaling at the sprint transitions. BTW: Using a Bianchi 928 with a 10-sp cassette on the Victory trainer; Zwift cog is off. All recordings were made with a Coospo CS500.
Hi, sorry I am not understanding exactly. In my mind slope mode and resistance mode are the same just different unit of measurement but I am not sure if that is actually true and especially not sure for a specific trainer. What happens when you use slope mode and shift to set power targets?
Here I show how I design shorter efforts in slope mode

Alex, thanks for your response. I share your view about slope being a resistance proxy with different units. I’m going to repeat my experiments under more controlled conditions to aid comparisons and help others repeat them if they wish. In the meantime, I need a clarification; when you write “use slope mode and shift to set power targets”, do you mean erg mode shifts to slope mode at the hi-intensity interval start, and then slope shifts back to erg mode at the interval end?

I mean when using slope mode you shift with shifters on your bike. So there is zero delay other then the delay in your bike derailleurs, which should be fast or at least very predictable and fast enough (like outdoors). Just click on slope in our app, and go to like 2-3% slope with arrows at the bottom and test this with using the shifters on your bike. One you have verified this works, you can program automatic slope mode changes to change the slope angle (i.e. resistance) right before any hard intervals like I did in my example provided in that link.
You can also leave your gears alone and just set up a slope workout. For example 5 minutes at 3% followed by a 2 minute recovery at 0%.
