to whom who might be interested:
There is no way to bring a trainerroad workout to a “Technogym Bike”.
What you can do is to analyze the workout from the bike in trainerroad. The steps are: sync the obligatory Technogym account (before the ride!) with Strava and connect the Strava account to trainerroad. Holz then, the workout will appear in trainerroad once completed on the bike.
From a hardware point of view, the bikes are good. Easy to adjust to your needs.
