CAROL Bike’s AI-Powered Cycle Gives You a Full Workout For Less
Working out is already hard enough - take the stress away with CAROL's smart, science-backed workouts.
The CAROL Bike always seemed too good to be true: jump on, pedal hard for just 40 seconds total, and get the same heart health perks as a 45-minute run. This big claim comes from two cool things: smart resistance that changes instantly to match where you're at physically, and a special high-intensity workout that's been proven to work by studies.

So, how does CAROL do it? It's all about those brief 20-second sprints. When you first use it, the built-in smart system checks your fitness and saves a personal resistance level that changes automatically each time you ride.
As soon as a sprint starts, the bike gives you the ideal load; once it ends, the resistance goes down so you can get your breath back. The system slowly moves the resistance up as you get fitter, keeping each workout right where it needs to be for the best results, without wasting any time.
Because the tough part is so short, the whole session, which includes warm-up, recovery, and cool-down, takes just five minutes, so you can fit a full cardio workout into your break. If you want something different, you can switch to longer workouts or steady rides. New support lets families switch between profiles without having to re-enter info. The app tracks your power gains, VO₂ max, and heart-rate recovery.
CAROL offers free shipping across the U.S., U.K., and Canada, has 0 percent financing, and gives every bike a 100-day home trial. If it doesn't fit your lifestyle, or you're not into the science, just send it back for your money back.
If you're ready to swap long cardio workouts for quick, proven effort, grab the CAROL Bike today. You'll be glad you took it for a whirl.
