Cancel membership for the bike

I had to cancel my Zwift bike membership today. I was using techogym skillbike and it got too hard.

For example it was easy to get 300 watts then next secound it was too hard get to 180 watts.

I do not know if was me or the bike techogym skill bike.

Like I was in the top 10 in the group ride today then got drop to 120.

Cant keep doing do this.

Good bye Zwift!(bike riding)
