Best indoor bike !

Great customer service. Easy to assemble. The bike is such a pleasure to use, very smooth and quiet. Incredibly adjustable for al size riders. Build quality is exceptional. Absolutely a commercial quality piece of exercise equipment. Could not be happier with my purchase

Very well designed and built.

As an avid 3 season road biker I was looking for something to keep me active in the winter. I’d been a gym rat but ditched my membership because of COVID. Never having had much interest in spinning classes, I was somewhat skeptical but I am now hooked. I add some upper-body kettlebell exercises and Swiss ball sit-ups, and pushups after my ride. The only thing I miss about my gym is the steam room. As some other reviewers have noted, my only regret is that I didn’t buy an M3i years ago.

Extremely happy.

Expensive? Yes. But, you get what you pay for. Very sturdy construction, and easy to put together. Very solid when riding and whisper quiet, even when standing. This is the highest quality that you would find in a gym spin class. Highly recommend if you're in the market.

Great quality bike

I love my new Keiser M3I bike. I got it to improve my fitness but also to train for longer bike trips outside. I wan’t sure about the connectivity of the bike to apps that I want to use. I have an Apple Watch and an iPad that I use. It works really well with Apple Fitness + cycling and I follow the teachers directions to increase intensity through resistance or peddling faster (more rpms). I have also tried out ROUVY together with the HeartCast app but have to select Indoor Cycle on my watch to get credit for the workout. I like how adjustable the bike is and find the gel seat cover helps with comfort. The YouTube video with directions on how to assemble the bike was very helpful. I can tell this bike is going to last a long time.

J’adore

Fell in love with an earlier generation Keiser at Cooper Fitness Center in the early oughts. I was in grad school at the time and not in a position to purchase one for home use. Fast forward nearly 20 years, the loss of my ability to jog, two surgical procedures for my abused ankles, and a series of life choices which would leave any cardiologists agreeing I needed to lose weight- a lot of it- I began investigating an at home cycling bike.
I had purchased (a non Keiser) one years ago and within a year, it was curbside, because despite great reviews, it just never “fit” my body. I knew the Keiser did, but it really was still out of my budget at that time.
Since then there’s been the launch of many competing at home systems. At the advice of some colleagues, I tried the largest...
Fell in love with an earlier generation Keiser at Cooper Fitness Center in the early oughts. I was in grad school at the time and not in a position to purchase one for home use. Fast forward nearly 20 years, the loss of my ability to jog, two surgical procedures for my abused ankles, and a series of life choices which would leave any cardiologists agreeing I needed to lose weight- a lot of it- I began investigating an at home cycling bike.
I had purchased (a non Keiser) one years ago and within a year, it was curbside, because despite great reviews, it just never “fit” my body. I knew the Keiser did, but it really was still out of my budget at that time.
Since then there’s been the launch of many competing at home systems. At the advice of some colleagues, I tried the largest at home cycling competitor [P], but I hated the subtle wobble I noticed on it. It seemed more like an ok bike with a proprietary “iPad” attached.
I finally decided if I was willing to consider a major investment in my future, it was time to buy the brand I already knew fit my body dimensions (5’6” middle age female- now with a gut) and felt 100% solid. The ability to move BOTH the seat and handle bars horizontally (in addition to vertically) is an immeasurable bonus for the female figure. The resistance lever is a breeze. The magnetic rear fly wheel is silent and perfect. I adore this bike.
I’m largely using apple fitness for my instructors. But am also trying said large brand competitor’s app for live and recorded sessions. A hot second online will find you a comparison scale of resistance for the Keiser to the competitor’s much larger resistance range; so it does “translate,” rather well.
I love this bike. I have had it for two weeks and have used it daily. I did start with only 20 min classes until my ample seat started to toughen up. But I am already up to 30 min classes and usually middle of the pack (burn bar stats for apple). I use it daily because it *fits* my body and feels like an amazing, well built cycle, not just a brand selling an ok bike with proprietary goods attached.
Bottom line: I’d encourage anyone to buy this bike. From there, you pick the app that works for you. But you will not stick to your fitness plans if the bike doesn’t match your body of feels poorly made. The M3 is 10/10 amazing.

(It took 45 min to EASILY construct by myself, with household feline and canine supervision.)

Keiser responded:

This is great, thanks for your review Tobe! You really highlighted the difference between our commercial-grade bike and the competition, which is designed to be convenient at the expense of the bike and the exercise.


All the best,

Beautiful machine

Very solid, professional quality construction. Absolutely silent operation.
The only thing I hear is my own huffing and puffing.

Great Bike

I have been a roadie for 40 years and had to quit riding an outdoor bike. I have researched at least five different stationary bikes and this is the best of the lot. It's well made, structurally sound, quiet, easy to assemble in 30 minutes with clear instructions. The only drawback is that I did not buy it two years earlier.
