CAROL’s AI-personalization and Instant Resistance help you push to your limits during the sprints. Like in a ‘fight or flight’ situation, your muscles are forced to mobilize about 25-30% of muscular glycogen—your emergency energy reserve—releasing key signalling molecules (AMPK and PGC-1a), telling your body it must get fitter and stronger.

That's because it contains a Cardiovascular Optimization Logic, known as CAROL, which means that each ride is bespoke and totally responsive to you.

CAROL not only watches your performance, her algorithms respond by automatically pushing you harder in subsequent rides or relaxing your ride if you have had a bad day. And it all happens automatically. You just log in and ride.
