What customers say about “Gear”

Keiser M3i

  • The drive train is as smooth as butter and doesn’t wake anyone up when I’m riding early in the morning. I purchased this bike for my ACL rehab. It’s been awesome and extra awesome with having to “shelter in place” during this CV-19 pandemic. I’m an avid outdoor cyclist and have been taking spin classes for years. Hands down this is the best indoor spin bike I’ve ridden!
  • Have been using the bike now for about a month. My whole family is using it and so far, it has been awesome and exceeded our expectations. The bike arrived well packaged. Assembly was easy using the instructions and videos available online. I have been using it with some available apps (GoIND) and it has synched perfectly every time. I have not tried the Keiser app. The bike itself is quiet, smooth, and easy to ride. Pedals work great. I use the cleats but my kids use the cages. Could not be happier. Well worth the investment.


  • I can’t tell you how grateful I am to have been introduced to Peloton. I started with the App and it didn’t take me long to get the bike. I absolutely love it. I haven’t stopped riding it since it arrived. It is amazing quality and I love the classes that I take on it. It pushes me to my limits and it was worth every penny. I am forever a Peloton believer.
  • The equipment is excellent, the trainers are so upbeat with great skills. It has been a pleasure in its use during the last two months with sheltering in place. From cycling to the floor classes Peloton has kept me smiling.

What customers say about “Connectivity and Subscriptions

Keiser M3i

  • I got it for me and now the whole family is using it. We like the adjustability.
  • This bike is so smooth and quiet. It gives a high intensity workout! We did a lot of research before purchasing and almost went with one that had the built-in monitor. I am so glad I did more research. We use our tablet or tv as a monitor and have so many apps to choose from. One of my favorites is BitGym. Don’t let the monitor be your deciding factor.


  • I go at my pace, find an instructor at my pace, and I love change so there’s plenty to choose.
  • + I love the outcomes, leaderboard challenges, and the Peloton world. The hate part is I don’t just love to jump on ride. With that being said, I love the challenges, the instructors, and the variety of options. I’ve enjoyed the cool down rides and stretches. I haven’t totally gotten ready to start the Power Zone series yet. Goals are PZ, the Hawaiian mountain climb, and Tour de Peloton. Not sure if I would have purchased if there had not been a showroom in town.
