The Sirius is a striking cycle trainer with an ergonomically shaped frame that gives slightly as you cycle. The magnetic brake consists of two discs, each of which has six permanent magnets. The 10-setting remote resistance lever changes the position of the magnets in the brake unit relative to one another.
The Sirius features a 2 kg balanced steel flywheel for a smooth pedalling action. The heavier the flywheel, the greater the mass moment of inertia.
