Great exercise option

I have used the M3 at work gym for the last 10 months and enjoy spending time keeping fit..whether a structured spin session/class or my own session I've loved it. So purchased a m3i for home use and it's great too..but as other users have commented I'm a little disappointed that it's not currently compatible with zwift/sufferfest etc. I'm aware this is in development but please hurry!
Lost a stone just spinning in 2018 so roll on the zwift/sufferfest compatibility 😀

Keiser responded:

Hi Nicki,


Great news! We are now compatible with Zwift through our M Series Converter, and though it is not available internationally just yet, it will be very shortly.


Thank you!

Great bike!

VERIFIED PURCHASE
This newest version is so nice. With the adjustable handlebars and the tray (my iPad mini fits in it perfectly), this bike is the perfect piece of cardio equipment.

Solid bike & exceptional customer service

VERIFIED PURCHASE
I purchased this bike for Christmas and have enjoyed every minute riding it. The bike seems exceptionally quite for a spin bike and is easy to adjust. The set up was fairly straight forward thanks to the the YouTube clip and manual. When I received the package, it was missing the sweat towel that we purchased but customer service quickly sent it out without hassle. I appreciate Keiser's customer service and am glad to have purchased a "Made in America" bike.

Replace the YMCA

VERIFIED PURCHASE
The assembly required moderate concentration for 45 minutes. The instructional video and booklet were excellent. Normally I'd pay someone to do the assembly, but in this case I'm glad I did not as it gives me a better idea of what I might need to do in the future to maintain the bike. It came with a gel seat cover, which is not necessary, as the standard seat is very comfortable. The bike posture and weighting of the flywheel are better than any other spin bike I've ridden. I had a question about the delivery and called Keiser and a courteous person answered the phone. I've been using the same bike at the YMCA for 3 years. I purchased it to replace my bike trainer when I train with Sufferfest Videos. I terminated my Y membership. I note no difference in the professionally maintained bike...

I purchased it to replace my bike trainer when I train with Sufferfest Videos. I terminated my Y membership. I note no difference in the professionally maintained bike and the one I assembled. I'm very happy with the result and my improved time management.

Solid as can be

Easy build. Rides smooth and feels stable out of the saddle. Super quiet. Resistance is incremental and graded. Aesthetically it is art in execrcise!

Great Stationary Bike

VERIFIED PURCHASE
Easy to assemble (they provide all the tools), very silent, perfect for serious indoor training. Integrated Computer measures cadence, watts, heart rate (with polar sensor, included in price). The bluetooth connection works well and allows to connect devices. However the MSeries app is a little "moody" (e.g. my daughter cannot connect her iphone).

Amazing bike. Love the new converter.

VERIFIED PURCHASE
I was planning to buy the Peloton but after some investigation decided that the Keiser M3i is a better choice. I didn't like the idea of having a limited use screen on my bike, it's just another thing that can break (I'd rather use my iPad or my TV). I also didn't like having to use only cycling shoes with the bike. The Keiser works with both tennis shoes and cycling shoes so the whole family and guests can easily use it if they wanted to. The converter really made it easy to choose between the Peloton and the Keiser. I do use my bike with the Peloton app, which is great but I also have so many other cool options to explore (Zwift, Sufferfest). So much fun.

Also, I tried the Peloton in the store and I think it wasn't quite adjusted to my height (I'm 5'2") because my back hurt a bit and I was worried that it would hurt more with continuous use. No problem with the Keiser, it easily adjusts to my height and also works well for my tall husband. Although it may seem like the Peloton and the Keiser cost about the same, when you add up shipping, extended warranty and accessories, the Keiser is a much cheaper option for a better quality, multi-use bike.

Happy birthday to me!

VERIFIED PURCHASE
At 53, female, I put it together myself, tools provided with video are most helpful. Saved $500 compared to pelaton competitor and with Free spin class videos available on you tube, no need for the pelaton pricey subscription. Smooth ride, sturdy construction, adjustments for multiple family riders and I’m recovering from hip surgery so the variation of ease and difficulty are just what I need to make a strong recovery. So thankful for this gift!
