A larger and heavier flywheel provides a higher moment of inertia and thus a significantly trägeres acceleration. If you try this effect on the bike and especially impellers to avoid, it is desirable for training purposes. Sprints can train more intensively, so that real sprints are even faster!
The larger mass provides an additional advantage of Kinetic Rock & Roll Trainers. The rapidly rotating disc weight stabilizes the roll stand on the gyroscopic effect. This results in an even more realistic driving behavior. Depends primarily because the self-stabilization "driven" by the rotating disk of the speed and of the severity of the lateral movement.
The flywheel is precision machined and balanced. Reinforcing vibrations are therefore not to be feared!
