Have you read the existing topic on the new V2 Kickr Bike?
Wahoo muddied the waters by releasing the new trainer and bike on the same day, with coupled press release, but I started a unique topic for each device. Per that, the link above covers what Wahoo claim to have changed / improved on the new unit. Maybe some of those relate to the “production problems” you mention?
Generally speaking, I am not sure many people have received these new V2 units yet, or at least not shared much feedback that I have seen. The V2 thread linked above is where that discussion will be found once it arrives. This current topic is essentially set for the V1 and I will update the title accordingly for clarity.
