Experienced rider but new to Zwift and Kickr v5.
The ramp test never increases resistance during the ramps. ERG on. Have rebooted, restarted, checked firmware, read Zwift’s troubleshooting sheet etc etc.
I’ve tried it multiple times over a few days. No luck. BTW, resistance works fine on normal rides. No issues there.
Any thoughts?
Hi @Michael_Albert1, welcome to the forums.
What device are you using to run Zwift and how are you connecting? Bluetooth or ANT+?
Using iPad with bluetooth.
As I mentioned above, works fine on normal rides, changes resistance on hills etc.
Is it possible to post a picture of your pairing screen? What is selected for controllable trainer?
Trying to find out how to post a pic here.
have you tried any other workouts to see if they are controlling resistance?
Yes, they all work fine. Resistance changes on climbs as it should.
Just want to confirm you are talking about other workouts with ERG mode enabled, not free riding where the resistance only changes on hills and such.
Oops. Just talking about free rides.
Haven’t tried a structured workout with erg enabled yet. Only three rides in.
Guess I should try that.
I thought I needed my FTP number for those but haven’t looked closely.
It is selected. I’m positive.
You will need an FTP for the workouts. Every time you do a free ride, Zwift will grab your best 20min power figure from it, if you set one. Do a few more vigorous free rides, or… eventually, when you’re in the workouts selection pane, your FTP will be displayed in the bottom right corner of the workout you’re previewing (it’s adjustable from there also—you can override it and type in any number you want).
Sounds like a good idea. But I want to eventually get a proper FTP from the ramp test, but I can at least test ERG mode this way.
…or you can drag the FTP slider bar in the right side of Mike’s picture up or down to adjust the FTP setting.
Tried an FTP workout and the trainer DID change resistance based on the target call outs.
So it just doesn’t seem to work for the ramp test.
This might be by (bad) design: FTP Test says somewhat ambiguously that ERG mode is disabled for the FTP test, which I guess makes sense for the straight 20-minute test, but I don’t really see what the point of disabling ERG mode for the ramp test would be.
It says to use ERG for the ramp test in other places.
So your logic is correct.
I’m having the exact same problem, erg mode is selected on ramp test. No problems with using Zwift up until this point, but absolutely no resistance offered on the ramp test, I could only do four modules by spinning faster and faster to get up close to even 160 W above that, my legs would spin right off.
Me too! I just tried a ramp test light as women under 60kg and I can’t go any higher than 150watts as my legs are going to pedal off the bike! Might have to try the FTP instead!
Me too. I’m only a few rides into Zwift and thought I’d try the Ramp Test Lite. Couldn’t produce many watts as my legs were spinning out in the hardest gear somewhere north of 130rpm. I got to about the 4th test and then couldn’t produce enough watts to keep going. There was zero resistance. To be honest, I didn’t know about ERG mode up to this point.
