About CAROL Bike

CAROL is an AI-powered exercise bike that provides a personalized training program based on the ability of the user.

The main program is based on a type of high-intensity training known as REHIT that has been designed in a lab, published in peer-reviewed scientific research and further refined by CAROL.

There are no dials or user input needed. The resistance is automatically adjusted from session to session based on feedback from previous rides and measurements captured by the bike. After an initial set of training rides each session will push you to your limits.

CAROL’s main exercise lasts just 8 minutes and 40 seconds. The bike guides you through two 20-second maximum intensity sprints, in between gentle warm-up, recovery and cool-down periods.

This has been shown to be the most efficient way to deplete glycogen and improve your aerobic capacity, and CAROL delivers double the health and fitness improvement vs moderate intensity exercise, in only 26 minutes per week

  • VO2max increases by 12% in only 8 weeks (vs 6% for conventional exercise)
  • Cardiovascular and metabolic risk factors reduce by 67% in only 8 week (vs 27% for conventional exercise)
  • CAROL burns 100% more calories per minute you spend on the bike vs conventional exercise


The idea for CAROL was conceived in 2012. Our team had been working on a chronic disease management program for Diabetic patients. The most significant barrier and excuse was the lack of time to exercise.

The science of REHIT (reduced exertion high intensity training) offered a solution. This type of exercise was only available in lab settings and needed a technician to operate the bike. In order to get the striking benefits shown in academic research:

  • The rider needed to exercise at their absolute maximum intensity
  • This requires a precise and personalised resistance to be applied
  • The resistance needs to be applied almost instantaneous
  • And at the right time after a rapidly accelerated pedalling at low resistance

CAROL replaces the technician with AI algorithms that determine the optimal personalized resistance for the rider and which continually adapt as they get fitter over time.
