How does the X-Bike provide a better “core” workout than a traditional indoor bike?
On a traditional rigid indoor bike with a fixed gear flywheel, the ‘equipment’ provides a stable platform on which the rider works. The handlebar rigidity forces the arms and lower spine to act as stabilizers while the transfer of flywheel momentum through the cranks means that the pedal acts as a stable platform on the upstroke. In essence, the stability of the equipment negates the recruitment of the core stabilizers. On the X-Bike, the natural, true-to-cycling movement of the handlebars and freewheeling drive train give the user fewer stable contact points and result in the engagement of the core stabilizers to fix the user over the bike in the appropriate position to pedal.
