CAROL bike for sale is a personalized artificial intelligence-powered stationary workout cycle. CAROL’s AI-powered algorithms use your biometric and performance data to create and apply personalized resistance in real time to achieve supramaximal power in every ride.

As a result, exercising for less than nine minutes each day for eight weeks can result in long-term fitness development. CAROL’s main program, created by scientists, lasts only 8 minutes and 40 seconds. All you have to do is pedal while CAROL uses AI-powered algorithms and scientific research protocol to adjust the resistance and power to your personal fitness level and performance capabilities.

Why choose the CAROL bike?

CAROL is your personal trainer and home exercise ergometer, both of which are approved by medical authorities and scientifically proven. It is a sturdy, durable, and silent exercise machine.

The CAROL bike features a very precise ergometer that regulates the magnetic brakes for supramaximal power, laser-guided motor controls, an HR monitor that collects ECG signals, a safety freewheel, and a quiet belt to mute out pedaling noise.

Even if you despise exercise, you may enjoy the Carol Bike. It’s an AI-powered smart stationary bike developed by scientists that promises to give the advantages of a 45-minute run in less than a minute. Its main training regimen consists of three weekly rides that last less than nine minutes and demand only 40 seconds of heavy effort. These REHIT workouts are designed to activate your body’s “fight or flight reaction,” allowing it to burn the sugar stored in your muscles as fuel. 

The Carol Bike, at $2,395, is almost the same price as a Peloton, but it’s not designed to imitate a communal training experience or entertain you. Instead, it’s all about having your workout done as soon as possible. It’s ideal for folks who don’t have the time or motivation to exercise, or for those who focus on a different activity, such as weight lifting or yoga, and want to get in some cardio quickly.

You’ve probably heard of high-intensity interval training (HIIT), but you’ve probably never heard of REHIT. This exercise strategy, as the name implies, is a reduced variation of HIIT that takes less effort.

REHIT programs, like HIIT, alternate brief bursts of intensive activity with rest intervals. The distinction is that REHIT exercises consist of fewer, shorter bursts of maximal intensity.

Your first six Carol Bike exercises are meant to acquaint you with the system and educate the bike’s AI how hard to push you. Its algorithms compute the amount of resistance necessary for you to attain your maximal intensity based on your performance.

Carol’s AI then monitors your stats and adjusts your resistance as needed to keep you challenged as your fitness level increases.

Carol’s REHIT program revolves around the company’s Intense rides. They begin with a light warmup, then a 20-second sprint, a recovery period, another 20-second sprint, a cooldown, and you’re through. The complete workout only lasts 8 minutes and 40 seconds.

Carol claims that these brief workouts provide the same advantages as a 45-minute run, and that doing three Intense rides each week for eight weeks has “been scientifically proved to yield double the health and fitness improvements of normal exercise.” That’s a lot of promises, and here’s the kicker: the firm urges you not to sweat during Intense sessions.

Does it sound too wonderful to be true? Carol’s brief REHIT exercises were “more powerful” than 30-minute moderate-intensity continuous training (MICT) sessions, according to a peer-reviewed study(Opens in a new window) by the American Council on Exercise (ACE).

High-end and costly

The Carol Bike has a stylish black steel frame with red and silver accents, a 10.1-inch touch screen tablet that doesn’t tilt or spin, and a comfy “ergonomically sculptured” saddle.

The bike, which measures 42.5 by 22 inches (LW) and weighs 130 pounds, is a suitable size for a small room and is quite easy to move around. It includes four leveling feet and two transport wheels on the bottom. It can fit riders ranging in height from 4 feet 11 inches to 6 feet 7 inches and weighing up to 286.6 pounds. The bike’s minimalist design lacks built-in storage places.

On the handlebars are heart rate monitors, as well as sensors that track your cadence (how quickly you’re cycling, measured in revolutions per minute, or RPMs) and resistance level. The tablet has twin front-facing speakers, a 3.5mm headphone connector, and Bluetooth connection for wireless headphones and heart rate monitors (but no ANT+ compatibility).

The Carol Bike, like the Bowflex VeloCore, has dual-sided pedals that may be used with or without clip-in cycling shoes. It incorporates an adjustable toe cage on one side for solid footing while wearing conventional exercise footwear. On the other hand, it has SPD brackets. The bike has a set of appropriate cleats that you can attach into the bottom of your riding shoes. 

Carol, like Peloton, provides a variety of packages, beginning with the Essentials bundle ($2,395), which includes only the bike and a one-year guarantee. The Standard package ($2,595) adds a chest strap heart rate monitor, a tablet holder, and a two-year guarantee for an additional $200. The most costly package ($2,795) includes all of the previously stated extras, as well as a floor mat, a water bottle holder that attaches to the bike frame, and a three-year warranty. The attachments can also be purchased separately.

Customers in the United States can finance the Carol for 12, 18, or 36 months through the third-party lender Affirm. Carol has a 30-day return policy(Opens in a new window), so if you’re not pleased with the bike, you may ship it back for free and receive a complete refund. Customer service is available 24 hours a day, seven days a week by phone, chat, or email.

A membership is required, as is common with smart home gym equipment, although Carol’s is less expensive than most, at $144 a year (which comes out to $12 a month) after a three-month free trial. Most rivals charge between $29 and $39 per month for a class subscription that includes exercises on and off the equipment, performance monitoring capabilities, and the possibility to create numerous user accounts per household.

Carol does not provide trainer-led sessions or off-machine exercises. Its subscription(Opens in a new window) provides access to the company’s tailored, AI-guided exercises as well as the ability to establish up to eight distinct accounts to keep everyone’s numbers separate. Because the bike’s AI automatically changes the resistance according on your skill during each ride, it’s critical that everyone who wants to use the Carol creates their own account. You may still ride the Carol as a standard stationary bike without a membership, but the AI functions are unavailable.

You may add additional variation by installing the Peloton Digital app ($12.99 per month after a 30-day free trial) straight on Carol’s iPad. When streaming Peloton courses on the Carol, you’ll see stats like RPM, output, and heart rate on the left side of the screen, and you’ll be able to change your resistance from 0 to 100 using a slider on the right.

You can’t use Apple Fitness+ ($9.99 a month) on the Carol tablet, but you can put the bike in Free Mode and use a different device to follow along with Apple’s cycling routines. If you want to go that route, you’ll need a phone or tablet holder for your bike, which Carol offers for $99.

Carol charges an additional $150 for expert assembly. If you select this option at the checkout, a technician will assemble the bike, link it to your Wi-Fi, and remove all packing. If you opt to build it yourself, you should solicit the assistance of another person because some of the components are hefty. Carol estimates that self-assembly should take roughly 45 minutes for two individuals. The bike includes all of the necessary tools. This article(Opens in a new window) describes the assembling process so you know what you’re getting yourself into.

Exercise on the Carol Bike

There are tabs at the bottom of the Carol interface for Select a Ride, Dashboard, Rides, Trends, and Weekly Leaderboard.

Carol provides many training options on the Select a Ride page, including Intense (20-second sprints), Energizer (10-second sprints), Fat Burn (10 minutes, 30 sprints), Fat Burn (20 minutes, 60 sprints), Free Ride (continuous power), and Endurance (continuous ramp up).

The firm advises two to three Intense rides each week as a starting point. Then, depending on your objectives, you may mix in the other routines. If you want to reduce weight, you may perform two to three Fat Burn rides each week in addition to your two to three Intense rides.

Carol has a section on its website that describes its goal-based programs(Opens in a new window), but it might make a better job of merging this information into the bike app experience. Peloton, for example, has revamped its Programs section to provide more regulated training regimens with suggested timetables, a progress report at the conclusion of each week, and badges for your accomplishments.

After selecting your workout on the Carol, you may choose from six music options: Tiger, Triumph (my personal favorite), Mellow, Escape, Electro, or Lounge. When you’re ready, hit Start to get started.

A Power meter that progresses from blue to red may be found on the left side of the Intense workout screen. You’re doing this during the warmup, recovery, and cooldown periods.

A Power meter that progresses from blue to red may be found on the left side of the Intense workout screen. You should keep your power inside the blue zone during the warmup, recovery, and cooldown (20 watts or less). Your RPMs are shown in the centre of the exercise screen. Your heart rate is displayed on the right. Below that, it displays your greatest and most recent Peak Power and Octane Score, goal and actual number of rides done each week, target heart rate range, and Max Heart Rate during the last session. A timeline at the bottom of the screen displays your position in the workout.

A countdown at the top of the screen ticks down to the next training phase. When it’s time to sprint, the screen will turn red, signaling you to ramp up the pace and begin pedaling as quickly as you can. The resistance will increase three seconds after the screen goes red.

The entire idea of the workout is to go all out during that 20-second sprint. If you chose one of Carol’s music selections, the beat will begin to build up just as a sprint is about to begin (music is only timed with sprints during Intense sessions), urging you to cycle faster.

One of the Carol’s advantages is that it provides real-time feedback on your performance. Following your initial sprint, a graph with a blue line reflecting your power throughout the 20-second effort displays. The graph displays your Peak Power score, providing you with a target to beat on the second sprint. 

After your second sprint, it will add a red line to the graph to reflect your performance for that exertion, making it easy to tell if you fared better or worse.

Carol provides a breath pacer at the top of the screen to guide you to inhale for four seconds, then exhale for six seconds to balance your nervous system during the warmup, recovery, and cooldown phases.

Tracking Your Progress

Carol recently redesigned the bike interface, adding Dashboard, Rides, and Trends sections that are chock-full of data and statistics to help you track your progress and compare your fitness to your peers. This information was previously only available through Carol’s web dashboard and smartphone applications, so integrating it directly to the bike interface makes it much more accessible.

As part of that release, the company added several new user-requested metrics, such as your Functional Threshold Power (the average Watt power you can sustain for one hour), Maximum Aerobic Power (the maximum Watt power you can sustain for a short period), and Maximum Anaerobic Power (your average power during sprints in an Intense workout), to track over time.

The Dashboard tab displays your Octane Score (Carol’s key metric for cardiovascular fitness), Calories Including EPOC (Excess Post-Exercise Oxygen Consumption, or “after burn”), Peak Power (measured in Watts), and Energy Output (measured in Watt Seconds) for your most recent Intense ride, as well as a monthly calendar indicating when you worked out. The app also keeps track of the total number of rides you’ve done for each type of activity.

You may get additional information about each measure by tapping the little information icon next to it (Opens in a new window). For example, your Octane Score “reflects how many heartbeats are necessary to achieve the Energy Output in an Intense ride,” with the higher the number being better.

Calories EPOC measures the amount of energy used by your body during and after your workout. Carol computes it based on your bike power readings. “These are ‘active calories’ only…and do not include your baseline caloric expenditure,” the bike warns, implying that its calorie burn estimations may differ from your smartwatch’s. “Smartwatches estimate your calorie expenditure solely based on your heart rate and do not account for EPOC,” so those totals are likely to be lower.

All of the exercises you’ve done in each category are included under the Rides tab. A graph at the top compares your data for each session (Octane Score, Calories, Peak Power, Energy, and Max Heart Rate) and displays whether the program raised, reduced, or maintained your resistance. You can also examine all of your metric graphs for that session by clicking on each entry.

Graphs representing your Octane Score, Peak Heart Rate, Burn (Calories including EPOC), Peak Power, and Energy Output over time may be seen in Trends.

The Weekly Leaderboard page displays how you compare to other users for the many metrics Carol monitors.

Work Out Smarter, Not Harder

The Carol Bike’s REHIT exercises promise to give the health advantages of traditional exercise modalities in a fraction of the time. Its artificial intelligence evaluates your talents before tailoring your resistance during brief sprints meant to swiftly drain glycogen stored in your thigh muscles. You exercise at your highest intensity for 40 seconds, and you may track your improvement over time and compare yourself to your friends. The bike itself is well-made and includes various built-in safety elements, as well as the option of wearing cycling shoes or standard sports footwear.

It’s a good choice for individuals who are short on time and want to get some cardio in without sweating too much.

It is, however, one of the most expensive smart stationary cycles on the market, at $2,395 (plus $144 a year for a subscription), and it misses many of the features found on competing machines, such as trainer-led courses, popular music, and off-the-bike exercises. Though their monthly membership rates are more expensive, the Peloton Bike+ and SoulCycle At-Home Bike provide greater variety, including strength training and yoga routines to supplement riding sessions. The Carol features a smaller screen than competitors in its price range and no built-in storage, not even for a water bottle.

Meanwhile, if the Carol Bike appeals to you, the Bowflex VeloCore ($1,699 plus $19.99 a month for membership) is another option. It, too, has AI-powered exercises that adjust to your fitness level as you get better, as well as trainer-led courses, a bigger screen, Netflix connectivity, and a unique leaning function that trains your core and arms.
