Read real reviews from riders who’ve experienced CAROL’s benefits themselves.
"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."
"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.”
“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!”
“This will help anyone get into the habit of exercising and will also support high performance athletes in reaching higher levels of strength and fitness. I recommend the purchase of CAROL without any hesitation!”
“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.”
