INDOOR TRAINER Brizon believes that the ideal trainer can simulate body and bicycle movements while riding outdoors. When training with settings similar to the actual ride, you can get a good balance on your bike and train to coordinate the complex movements of the same muscles you use while riding outdoors. Cycling is a balanced act. Your body and bike need to work together to maintain balance and stay upright. For example, gravity, the force pushing the pedals and pulling the handlebars, the forward movement of the bicycle, and the resulting inertia, all need to work in harmony.
