Family of 5 loves CAR.O.L. Aged from 44, 42, 17, 14, 12. We received the bike fully assembled within 10 days of ordering. It’s beautiful and well made. All of us are working our way through the initial protocols. It’s exactly as described. Easy and effective.

I have had bike 2 weeks now. I must say I am impressed! I am using it and it is working. In a strange way the AI aspect of Carol makes it feel like you have a coach that cares.
Every time I get off the bike I am energized.
And I actually want to use it! Dave Asprey of Bulletproof is right…..this won’t turn into a clothes rack!!

I am impressed by CAR.O.L, within 15 minutes of finishing a workout it seems the endorphins are flowing as I experience a very positive mood shift. I’m 33 and bought the bike for my NYC apartment during the covid 19 lockdown restrictions. The workouts are short and very intense. I think the brevity of the workout is why I have had no problem incorporating them into my daily routine (a 10 min ride 4-5 days a week).

The CAR.O.L bike has solved my life-long exercise “problem”–three, 8 minute and 40 second “rides” on CAR.O.L each week (against optimal resistance) gives me all the health benefits (and more) of the Center for Disease Control’s recommended 150 minutes a week of moderate intensity exercise! It seems too good to be true, so I spent a month and a half checking out the worldwide research on HIIT and ReHIIT (Martin Gibala’s “The One Minute Workout” sums up most of that research), and asking questions of everyone at CAR.O.L (Rahul, Rose and all were patient and informative)–and it is true, all true! I’m 77 years old with coronary artery disease, A-Fib, hypertension, and other “dents” in my fenders, but after testing, my cardiologist approved me for those two all out sprints on CAR.O.L, three times a week. I have been riding on CAR.O.L for only about three weeks, now, but I feel great mentally (no more dread of exercise times), great physically (more energy, more active), and, no more drudgery–I’m challenged on every ride by CAR.O.L to beat my best power and octane scores. Ordering, delivery, and set-up were all exceptionally easy and very well done. The customer service is 24/7 and really strives to please. I feel like the Good Fairy has zapped me with her magic wand–only 8 minutes and 40 seconds, three times a week, and I’ve performed the cardio exercise that I need for good health. Absolutely amazing! My exercise “problem” is solved.

I bought CAR.O.L for my hubby’s big 50. She is a shiny fun addition to our home. The short workout makes her an easy addition to our morning routine. It was seamless. He puts the coffee on and sits down with CAR.O.L. By the time he is done, coffee pot beeps!! Health is within our reach. CAR.O.L makes it easier. We are lucky to have her.

A very impressive start as a new owner. As a long time runner I have found the switch to using the bike very impressive. On my second week of rides and I can already see it is going to be very successful in improving my overall fitness and running – especially for my leg strength. . Very good support – we have received very full answers to questions we have had on optimise our use of the bike. Very popular with all the users here and we will be recommending the bike to everyone we know.

I love CAR.O.L and I’m really enjoying seeing my improvements! There’s always time to get a workout in, no matter how crazy my day gets.

I first heard about the CAROL bike last year and didn’t think I could afford it. After the COVID hit this spring and I couldn’t go to the gym anymore, I decided it was worth it to have something at the house I could do to with little time. I’ve only had a bike for a week but look forward to riding it daily. My husband was very impressed with how well it is built and easy to put together.

I bought this bike because I’m lazy/easily bored. I know that if I’m supposed to do something for 45 minute or even 30 minutes, I’ll lose interest quickly. So the idea of sub-10 minute commitment sounded great. And it has been! I jump on the bike when I realize “oh I have 10 minutes till ___, that’s enough time to get a workout!”
Because resistance goes up as you get stronger it’s always super-challenging but when you do the basic (energizer or intense) ride, you don’t even get sweaty.
And you have the ability to do other rides, including longer ones, you just don’t have to! All in all, it was a great investment for short-attention-span me!

I’ve had my CAR.O.L for four weeks now and have been riding it every other day. At the beginning of each week I’ve been monitoring several vital signs and most importantly to me I am pleased to see my fasting blood sugar drop from 101 to 84 in three weeks!! This is the best investment one could make!

So, we closed our gym when we moved, and opted for a CAR.O.L bike for interval training, glycogen depletion, and a regular series of butt-kicking that would surpass my expectations. No joke – not your father’s exercise bike. If you’re looking for an all-weather, exercise option at just 10 mins 3x/week – mercy. This is the bike.

I bought CAR.O.L on December 2019. Beside it is world’s first AI-powered exercise bike, a session takes under 9 minutes with only 40 seconds of real effort and delivers the benefits of a 45-minute jog. I have no excuses not to workout. Plus CAR.OL and her smart AI algorithm personalizes and optimizes my resistance so I hit max intensity levels and maximum glycogen depletion every time. So I dont have to figure out or cheat myself for my real ability. Kudos to the customer service. They are prompt to answering all my questions no matter how big or small. It is one of my best buy for 2019. Worth every penny. The price is comparable to the “other” bikes but they are not as smart as CAR.O.L and less time with max result. Totally worth it.

love my CAR.O.L! In my opinion and from evidence based research, putting a demand on your mind and body in a short period of time is the most effective way to improve your bone, muscle and heart strength. Carol does it all in just minutes and only 2 times a week? It’s hard to believe at first, but take a controlled, smooth 2 minute warmup ride, then spin hard for 20 seconds, then take a 3 minute relaxed recovery ride and one more kick ass 20 second sprint with a 3 minute cool down. That’s only 8 minutes of a stroll and 40 seconds of personalized, computerized resistance. You’ll feel the magic. And she gives you an up to date report card on your on going progress after each ride.
There will be no doubt that your glycogen will be depleted and “poof”…you will become a “mean, fat burning machine” within minutes!!
Thanks to CAR.O.L.
I’m turning 72 years old. I’ve been a certified personal trainer in the HIT business for over 20 years. The CAR.O.L bike has now been added to complete my efficient, effective and safe strength training and cardio training tool box. And it’s a space saver. My clients LOVE it because it backs up with results.
The support system from the CAR.O.L team is top notch. They are quick to answer and solve any questions or concerns. It’s a flawless company with an amazing, state of the art, quality built machine that they back up with human care. And the price is right.

Just finished my 111th CAR.O.L ride! My max power has increased 36% and my octane score has increased 23% since starting. It feels great on this 70 year old body! I’ve seen some significant improvement on my outdoor riding as well. I’m currently aiming for at least 4 rides a week using both intense and fat burning modes
I’ve had only a few instances where I needed to contact customer support and they were also great. My questions were answered quickly and professionally.
I highly recommend CAR.O.L. to my friends and family.

I purchased the bike 4 months ago and have been using the Intense protocol as recommended 3 times per week. All I can say is the bike truly delivers a time efficient , kick ass workout with the two 20 second sprints and my results went beyond what I thought was possible. The personalization of each ride by C A R. O.L makes it very challenging every time. I also want to commend the support staff that I spoke with when setting up the bike. Truly professional and prompt with their service.
I highly recommend this product to anyone looking for a better way to workout!!!

I had trouble connecting to router. I contacted support for help. The response was very quick with clear alternatives to try at home – this allowed me to connect to my home wifi. Also, support called me to follow up as well, which was informative, as we had a great chat. I am looking forward to becoming more fit with the help of the CAR.O.L. team.

awesome service.. probably the best I have ever had with a vendor. everyone is fast to reply. helpful and so polite. would highly recommend!

I love this bike. It makes it so much easy to work out in a busy today with work and kids. I would highly recommend it!!

This bike will change the way we age! I am 71, my spouse is 62, and we needed efficient cardio that kept us motivated. We have done 10 rides, and I can already see a difference in my energy, and my breathing. The quality of support is stunning. Anything I ask is answered immediately and with a spirit of “so glad you asked”. I just had an illuminating conversation with the Director of Sales and Marketing, who gave me new reasons to love this bike. Thank you, everyone at CAR.O.L, for making this possible. And your brilliant support.

I have had my CAROL for one month now and I love it. The less than 10 minute session is easy to work in first thing in the morning and leaves me feeling energized all day. As great as the bike is I find customer service to be equally impressive. I have contacted CAROL customer service twice and both times the representatives were prompt and knowledgeable.. The first time they helped me determine which rides to use daily to match my fitness goals. A month after that conversation I have been impressed enough with bike that my second conversation with customer service was to order a second CAROL to be shipped to my Father. Thank you Team CAROL!

CAROL is absolutely phenomenal and one of the best investments we’ve made into our private home gym/wellness space. For one, there’s never an excuse time-wise to not get in movement for the day and push yourself. Even on the busiest of day’s, I can always find time to push myself and the bike pushes you beyond what you’d be capable of otherwise hands down. In 1 month, my peak power has gone up by 100 watts, my Octane Score (recovery ability) has gone up by 8% and I can see the visible differences in my overall body composition
Second, the CAROL support team is amazing. Extremely responsive and has already pushed out several improvement updates to our bike within the month and take great care of you.
Third, the bike helps you get back into ketosis extremely quickly after a carb-refeed. The next morning after a weekly carb rereed, do an Intense CAROL ride and your glycogen will be depleted rapidly and get back into keto faster than ever.

I don’t know how to put into words how CAR.O.L has transformed my life. I have never been overweight. In fact, I’m what they call “Skinny Fat.” I love to eat so I work out just to stay status quo but I always had the desire to lose 10lbs. I just couldn’t no matter what I did until one day when a FIT LAB opened up in my office building. I had never heard of CAR.O.L, in fact, I didn’t believe it. How could 2 -20second sprints help you lose weight and more importantly, help your heart? I asked the same question time after time. Until one day, I stepped on the scale and to my surprise….I had lost 12lbs…..Keep in mind that I eat out 2 meals a day, every single day. Losing weight has NEVER been easy for me. I lost 12lbs without changing my diet. I LOOOOOOVE CAR.O.L It is the most amazing piece of equipment. Well worth the cost.

I have just ordered my own Carol bike after riding a friend’s for a month and experiencing the results.

I have been using the CAR.O.L bike 2-3 times a week since December – it has basically replaced my gym sessions! I have noticed an improvement in stamina and the fact that it’s such a short workout is such an encouragement.

I’ve been exercising every day since I got the bike. It’s so fun. I´ve recommended it to some of my friends
