Erg mode Wahoo shift bike

hello

what am i doing wrong😊.

wahoo shift bike i use my wahoo roam and i adjust erg mode there eg: 200 watt and bike on zwift works erg mode.

i do work out in zwift, training from there with erg mode on in zwift i have those peaks and erg mode does not work, see photo.

thanks in advance

It’s hard to tell without more information but, to me, it looks like you’re ’chasing watts’ (changing your cadence to try to hit the watt targets). If this is the case, just try to keep your watts constant and let Zwift adjust the trainer resistance so that you stay at the correct watts.

ok thank you and what other information would you need?

You need to pair the bike to Zwift for both resistance and power, it also looks like you don’t have cadence paired from the bike. If you still have your bike paired to the Roam then Zwift can’t control it and the workouts will not work in ERG mode. Get rid of the Roam and it should work.

ok thank you

so:
power source
resistance
cadence

all 3 must be connected via bt ?

is apple tv

yes, connect everything to the Apple TV, leave the Roam powered off.

I’ve paired all three.

ERG mode works during Zwift workouts, but the wattage doesn’t stay consistent like I see with other people using, for example, the Wahoo Kickr V2, etc.

I’ve seen others mention the same issue with the Wahoo Bike Shift on forums.

When doing workouts without ERG mode, I’m better able to hit the target wattage.

I assume you already have ERG mode power smoothing turned on in the Wahoo app?

Also, before you start your workout, shift to the easiest gear (i.e. 1-1). This was mentioned by GP Lama in his review video of the Kickr Bike Shift on YouTube as a way of improving ERG mode. I do it for every workout and it does make a difference.

However, due to the design of the Kickr Shift, ERG mode will never be as good as the Kickr Bike or Core etc. Wahoo have admitted this.

Shift works fine in ERG mode with Zwift, so its going to be something in your set up.

As others have said, only connect to zwift initially so you dont have cross talk and any other devices trying to control erg. Failing that, pedal smoothly and keep cadence fairly consistent.

ok thank you and what gear do you mean exactly with 1-1
which outer chainring and rear

Oké thanks en Gears? what is the best gear then with wahoo shift bike for Erg mode

what is the best gear then with wahoo shift bike for Erg mode

If the gears are showing you are not in erg in mode..

ah okay but the wahoo shift bike is still on a gear when starting up and apparently this should be 1-1, and now my question is what is 1-1. thank you

weird:

my woosh works very fashion perfect with wahoo bike

zwift, not at all…

so it’s clearly due to zwift

Hi @Bike123

Shuji at Zwift HQ here. I’m also an Apple TV user.

Would you try power cycling the Apple TV as a first step? There are three ways to do that. This will clear out app cache.

If that doesn’t help, try uninstaling the Zwift app and re-install. Here’s how. This can help if files have gotten corrupted.

1-1 is the equivalent of the smallest chainring and biggest cassette cog.
Obviously you don’t see the gear display in ERG mode, so when I start a workout and before I pedal, I just press the outer (the larger) shifter about 10 times so I know it’s in the easiest gear.
If I forget to do that then ERG mode is like what you experience.

ok great clear explanation.

press left shifter a few times so it goes to inner chainring and shift right shifter up so it is on largest cog.

Correct?

Thx
