LOVE MY KEISER!

VERIFIED PURCHASE
We bought the Keiser M3i because I was having knee pain using a treadmill and needed to go to a low impact exercise. My husband only buys the best of the best, so he did his research and bought the Keiser M3i. I LOVE it! Set up was easy and we were able to make every adjustment to match my height and frame exactly. Perfection! And no more knee pain!

I’ve ridden them all... Keiser is the best ride out there.

VERIFIED PURCHASE
First, I belonged to a spin cycle club for 2 years riding a Schwinn Performance Carbon Blue. The classes blared the music so loud that I needed earplugs. The bikes were a calibration nightmare and no one bike rode the same as the next.
Then I moved to a regular gym where I could use their spin bikes alone, at my desired time, for as long as I wanted, and without the blaring hip-hop noise. I rode the Keiser M3 for the next 2 years. I loved it!
The Keiser M3 was sturdy, whisper quiet, reliable, and without any complications. The footprint was smaller than other spin cycles I rode as well which was crucial for my small living space. I knew I wanted one for home!
Later, I tried out the new Peloton cycle. Yes it is fancy & high tech, but...

Later, I tried out the new Peloton cycle. Yes it is fancy & high tech, but I worried about the high maintenance costs if the monitor screen ever went on the fritz, and at some point it will. Also, I was not interested in ONE MORE electrical gadget to plug in, and connect to WiFi. Plus you have to pay a monthly fee to connect to Peloton classes. Just NO!
In conclusion, I knew that the Keiser M3I was the cycle for me. It proved itself for years on end at a busy gym. It was easy to assemble on my own with the special tool kit from Keiser. I chose not to buy the Bluetooth connection since I personally don’t need to connect to a class. The display screen is the size of a deck of cards and displays all the info I need.
If I decide I need more motivation later, I can turn on my large screen TV and watch pre recorded spin classes that way. The Keiser M3I is about simplicity, low maintenance, precision, quality, and durability.
One more thing, the Lifecycles I have owned & used at gyms are heavy, clumsy, clunky, and NOT. A smooth ride at all.
The Keiser brand is the best quality spin cycle out there in my opinion.

Price not worth it

VERIFIED PURCHASE
I like the bicycle. If you are looking to just buy the bike it is an excellent 5-star bike. I purchased the M3i because I was interesting in the intelligence part through the Bluetooth converter. I was hoping to be able to have an easy experience with Zwift and the Keiser App. I am on probably my 10th 2032 battery. The Bluetooth converter is heavily discounted because Keiser knows that it is barely good enough. If you are hoping to buy this for Zwift I would look at other cheaper options.

I would not recommend if you are looking for bicycle for Zwift.

Keiser responded:

Hey Sheldon,

Wanted to thank you for the help you've been in troubleshooting your converter, I do wish we could have improved your digital experience to match the cycle experience.

We have made great strides with the converter with the latest firmware update, we focused on battery life and it's much better now. I will be sure to reach out to you with any news on the digital front.

Best,

Amazing Quality

VERIFIED PURCHASE
I originally bought a Schwinn IC4 in order to save a few dollars. I am an experienced outdoor cyclist, and the IC4 did not have the quality feel that I was hoping for. I returned it and bought the Keiser M31 The M3i is amazing. The bike is very well designed and is quality from top to bottom. The ride is wonderful, repeatable, and solid. I look forward to my indoor workouts now.

Superbly designed and built

VERIFIED PURCHASE
Have absolutely no complaints. It is all it is said to be and worth the money.

Keiser responded:

Thanks Phil! Much appreciated, was there anything else we could have done to improve the experience?

Hope you're staying safe out there,

Closest to the real thing I've found.

VERIFIED PURCHASE
This is a great, well built bike without the need for a monthly subscription. As a physical therapist, I can validate that the adjustability of this bike is excellent and will fit people of different sizes with good biomechanics. This is the closest feeling to a real road bike that I have found.

Fantastic

VERIFIED PURCHASE
I was looking for a quality spin bike to provide cardiovascular exercise and strength conditioning for my road biking. I purchased the 3Mi based on the outstanding design, engineering and positive reviews. Spin bikes that I used at the gym had heavy flywheels and a knob that changed resistance. The 3Mi uses a lightweight flywheel and precise magnetic resistance gear selection that create a road bike feel. Coupling to the Zwift app (using the M Series Converter) on my iPad adds to the effect of being on the road. My workouts are rigorous, satisfying and enjoyable. Thank you, Keiser.
