After years of lusting after a smart trainer bike, I made the purchase and I'm happy with it. I previously had a Tacx Neo and an old, permanently mounted MTB with a Sterzo. (Also Tacx rocker plates, which I don't recommend.) Apart from the cost, I agonized over Tacx vs Wahoo bikes for their features. From a Tacx Neo I really liked the entertainment of the road feel feature and didn't want to lose that. I also really liked the Sterzo steering and thought I would miss that with the smart bike. In the end, I do miss the Sterzo; buttons are not the same. But overall the other features of the bike outweigh this.
Likes: Stability and sturdiness, which helps in terms of getting out of the saddle, for some relief if not power. Overall build quality. Contact points and adjustability. Shifters and feel of the brakes (although I never use the brakes!) which add to the virtual reality of the bike experience. The phone tray. The iPad holder.
Dislikes: None. (But even an awesome indoor trainer is still an indoor trainer and long rides on a trainer are still kinda painful.)
