Hello all

I be just set up my cadence meter devise in the app
I have selected the tire size
I have selected « not referenced home trainer «

When I start the race
I see the rpm raising but the speed remains at zero
And I my character is not moving at all
What ever the rpm is …

Any idea ?

Hi @Laurent_D_Antibes, you need a speed sensor, not just cadence, for Zwift to work and a supported trainer.
