Never been a spinner but I needed something to save my knees from running. So far so good. I love the bike. The app could use a little bit of an upgrade though

I was on the fence about buying a "spin bike". I love to run, do Plyometrics and lift heavy weights but at 47 my injuries have caught up to me (Army, pickup basketball, Soccer, Tough Mudders ...at a current 225 lbs ).

I was torn between an elliptical trainer & a peloton. The interactivity of the Peloton was a strong selling point but I didn't want to be locked into one companies app which I may not want in 10 years so I wanted to choose an app independent cardio machine.

e.g. Maybe I want to try road racing (Zwift) or a different spinning company (Soul Cycle). Who knows what I'm thinking in 5-10 years?

I took a chance on Keiser after reading very high reviews - and I'm so glad I did. The ergonomics & quality of the bike is amazing! Biking "out of the saddle" (off the seat) gives a very similar feel to an elliptical, but with far more options for movement (e.g. sitting w/heavy resistance to feel like biking up a hill).

Me and my 2 daughters are using it nearly every day (I lift with dumbells 2-3x per week & use the Keiser to warmup).

Brilliant non-impact workout that works the muscles and not the joints. The resistance is smooth & even at the highest levels.

I couldn't recommend this purchase enough - amazing!

Loved this bike so much we purchased another.

M3i adjustable handlebars are a must vs the M3. Love the bike and instead of sharing with my spouse, we purchase 2 so we can ride together. Smooth ride and appreciate having the adjustability options to work with each individual body. Recommend riding with clip in cycle shoes, makes a difference in your workout. I highly recommend the M3i and optional tool kit to put it together. Easy to understand instructions for assembly and then you have the tools for any needed maintenance later. Customer Service has been great!

VERIFIED PURCHASE
I had used this bike at the local YMCA when I was a member a few years ago. Like others, I decided that being at home and unable to go to a gym was a good time as any to make the investment and get my own bike. I use the bike daily and am impressed with the quality. It is practically silent while in use and rides very smooth. The shipping time and packaging were excellent - while the outer box was heavily damaged the bike and all parts were packaged well and survived the cross-country trip. I did not purchase the maintenance kit as I had most of the tool required are pretty standard and I had them in my toolbox already. I use the bike with the Peloton app and have also used it with Zwift and FulGaz. I prefer...

I did not purchase the maintenance kit as I had most of the tool required are pretty standard and I had them in my toolbox already. I use the bike with the Peloton app and have also used it with Zwift and FulGaz. I prefer the classes, so I use the Peloton app daily. My one issue was with the converter that I purchased as an add-on. The battery was not making good contact in the unit and it was not connecting with the Bluetooth in the apps. A folded piece of paper did the trick by proving enough pressure to make continuous contact and allowing the converter to communicate with the apps. I have not used the included heart rate monitor as I use my Apple Watch instead. I love this bike and would definitely recommend it!

Keiser responded:

Dana,

Has your M Series Converter performance improved at all? Sounds like we might want to consider replacing it.

Thank you!

Superior my made, super quiet

I am thrilled with my purchase of the Keiser M3. It was easy to assemble, has a Sleek. Attractive design and is super quiet. It is extremely sturdy ans well made. When it got too hot to use in my garage due to a heat wave, I easily wheeled it into my home and was able to do my digital classes inside. I love the media tray.

The Perfect Product For Me

VERIFIED PURCHASE
Superb engineering. Easy to assemble. Quiet. Flexible; able to find the perfect fit. Visually appealing. Priced right to quality and value. What more can I say! Best Spin Bike I've ever used.

I live in a Active 55 community that has fitness equipment but the Virus Situation caused limits; ie, 45 minute appointment and masks required. I can't imagine riding a spin bike for 45 minutes with a mask. The Virus Situation required me to buy a spin bike for my home. I think that I selected the best one for me—Keiser M3i.

Best Health Investment Ever!

I love the magnetic resistance of the M3i! The seat is comfortable and changing gears are a breeze. It's hard for me to take a day off. I contacted customer support about what I thought was a problem and the response time was exceptional.
