ErgVideoTM operates your smart trainer in ergometer mode. This means you must output the power level it dictates. It's very different from course mode. Read about it in our FAQ here.
You can, of course, completely control the intensity of your ride. Professionals and beginners can ride together, and have exactly the same training experience!
ErgVideoTM is the ONLY virtual reality system that simulates the true demands of cycle racing. Your efforts are dictated by the rider's behavior, not only the course profile. In a racing ErgVideoTM, you will change speed and intensity often. Training sessions are less variable.
The smart trainer forces you to maintain the power level prescribed by the session's power profile.
