All moves, especially the ones to the side, have to be done wilfully (actively) by the test person. The animation gives an impression of what groups of muscles and what movements are activated by the SNAIX training.
This movement pattern we call "active mobilization".
 
With the push of the left pedal, the hip must turn to the right and the shoulder belt in the opposite direction (the left shoulder turns to the rear). With the step on the right pedal, these movements have to be coordinated exactly the other way around - an indoor exercise that already requires a great deal of coordinative effort and concentration.

The SNAIX neuro bike and the SNAIX studio trainer on the other hand are unstable in themselves.

Pushing the left pedal the bike instantly turns left as well as it turns the pelvis to the right. In order to be able to ride the SNAIX neuro bike at all (or to stabilize the SNAIX studio trainer), one has to apply within fractions of a second the correct counter acting forces to those forces applied to the pedals using the back and the saddle. This movement pattern we call "reactive stabilization".

Both patterns use identical muscle segments and neuronal structures - but in a "mirrored" way. Thus they add up to an integral and most meaningful training system.

Taking the SNAIX neuro bike into big turns, slalom or offroad it's 3D balance system is getting most complex up to the point, where riding the SNAIX neuro bike is probably todays most challenging training system for coordination, reaction and concentration and for highest demands.
