Isn’t ‘fixed wheel’ better?
Better if you want to cheat! If you pedal a fixed wheel bike flywheel up to speed and then take your feet off, the pedals keep turning! With a fixed wheel bike, the momentum of the flywheel drives the pedals round. If you relaxed your legs they would move, but would not be generating any external work – in other words they’d be making no positive demands on the body’s adaptive reserves. With the freewheel X-Bike, the pedals only turn when you make them turn. Without adequate resistance, the drive-train is slack and it becomes impossible to pedal smoothly – in effect X-Bike prevents riders from wasting time with exercise at too low an intensity to produce cardiovascular fitness gains.
