it was my fault, but customer service was amazing
I noticed a problem with my bike a few days after setting it up didn’t think a whole lot about it but then it recurred. I called into customer service. I received a call back immediately with full instructions pictures and easy troubleshooting. Mario was absolutely amazing to work with to get my bike up and running optimally, even though the issue was user error. Thanks Carol for a great experience.

The REHIT program accelerates progress
The REHIT program accelerates progress. The built in programming and recording of events creates the ideal feedback loop. It’s amazing how two 20 second blitz sprints can wear you out and the effect it has on VO2 progression. Would like to see a program that enables the rider to determine actual maximum heart rate; not having to depend upon an estimate. The CAROL chest worn heart rate monitor is a big plus as is the use of bike shoes with clicks.

Great to hear this — thank you for sharing!
We’re delighted you’re seeing the impact of REHIT and benefiting from the feedback and tracking — it’s great to know the short sprints are delivering real results for your VO₂ max.
We also appreciate your suggestion around determining true maximum heart rate — that’s valuable feedback and something we’ll share with the team as we continue to improve the experience.
Wishing you many great rides ahead!
Excellent product and customer service.

I love my Carol bike, and best support ever!
I love my Carol bike, and the results I've been getting with it, even a few times a week, have been amazing. Legs are stronger and more stable, and I don't feel so much like an old man going up stairs anymore!
I had an issue with the tablet not charging, and when I emailed them about it, they immediately got in touch with me, scheduled a phone troubleshooting session, and figured out the issue. They sent me the new parts, which were easy to install, and now everything works great. Such great support with amazing tech!

Just 5-minutes is all you need to significantly improve your health and fitness with CAROL—glad to hear you're feeling a lot fitter already!

REHIT has high impact!
I've only been using it for three weeks, but the feedback is easy to comprehend. I was skeptical about doing high-intensity REHIT three times per week. Just two 20-second sprints each session. Well, I had to drop down to two REHIT sessions per week to have adequate recovery time. Now, I'm seeing amazing increases in power output and fitness levels.

Scott, thank you so much for your review.
Doing 3x REHIT rides on CAROL Bike a week is scientifically proven to increase your cardiovascular fitness by 12% in just 8 weeks. With such a short workout time, it's so easy to make a fitness habit that sticks. And of course doing 2x REHIT rides a week is still fantastic, and I'm sure you'll get back up to doing 3 rides after your fitness continues to improve!
Unhappy
Well, I ordered the product and I was delayed week after week after week such that when I left the country and been gone for a couple months I have it still sitting there now. Wish I could’ve used it when they told me it would be shipped within 10 days, but it was more like two months.

Glenda, so sorry to hear this and we regret you didn't experience the usual excellent service our customers have come to expect from us. Your shipment delay was caused by a rare incident with our carrier. We are waiting for your confirmation to apply 90 days of CAROL membership for free as an apology for the inconvenience and a gesture of goodwill. Please respond to our email so we can get this applied to your bike. In the meantime, please do reach out to us if you ever need any assistance in the future.

Thank you for your review, Douglas.
CAROL is scientifically proven to improve your VO2max by 12% in just 8 weeks. And the best part? All it takes is 3x5-minute workouts, 3x a week. Great to hear your VO2max has improved already.
Keep up the great work!
The best workout bike out there
The best workout bike out there, well worth the cost. Best for those who don't have time or want the most out of their workouts. If you don't care too much for having an over the top flashy screen and care more about efficiency this bike is amazing. I lost so much weight doing the fat burn workouts everday. The Ai controlled resistance finds and sets my pace well and the subscription cost is way better than the other brands.

Alexander, thank you for your review.
CAROL Bike is designed specifically for REHIT—the world's shortest, most efficient workout. The Fat Burn workouts provide significant calorie burn in just a short workout time, and it's great to hear you've lost so much weight doing them.
Keep up the great work!
Slow shipping and High Replacement Part cost
I bought a replacement power cord and shipping was slow, even though up front I asked it be done ASAP. My other big disappointment was the price. $50, really. Are they trying to compete with the high price of replacement parts for cars. It is not like it is a high tech cord.
31 July 2025
Reply from CAROL Bike
Greg, so sorry to hear this. Our usual delivery times for replacement items are 1-2 weeks, and you received yours just 5 days after the invoice was paid. We knew you wanted it delivered ASAP so we offered the chance to expedite the delivery, however you refused. We still managed to deliver it in a timely manner for you. We provide replacement items at cost to us, so rest assured there is no profit in us sending these items, and in fact, we usually make a loss.
Hopefully this explanation can alleviate some disappointment here. Best wishes on your CAROL Bike journey.

I really enjoy working out now
I really enjoy working out now. It only takes a few minutes. I have it in my living room and I don't mind a bit. It looks nice and it reminds me to exercise should I forget, which is rarely.
I just really enjoy using it and I feel energized and good about myself after a session on my CAROL bike.

Melissa, thank you for your review.
CAROL Bike workouts are so short, it's easy to make a fitness habit that sticks. In fact, CAROL riders average 3.2 rides per week in their first 100 days.
Glad to hear you're really enjoying the bike and wishing you all the best in your health and fitness journey!
