There is a need for a more comfortable seat :)

Keiser Responded:

Hi Ramin Bet-Yonan,

Just a quick note that you can make your seat more comfortable in a few ways:

  • Add a "narrow" gel seat cover from Keiser or another manufacturer.
  • Invest in a pair of padded cycling shorts, available in many sizes and styles.
  • Replace the seat entirely!

All the best,

VERIFIED PURCHASE
This is my second M3i, having purchased one five or six years ago, and this one is for my wife. I initially made the decision to go with the Keiser by going to several of the local gyms and trying out the bikes they had. The Keiser blew the competition away. Most were wobbly, rattling, and malfunctioning. The one Keiser I found showed signs of use but was in perfect riding condition in a commercial setting where abuse is always a given. I was attracted by the more exotic electronics on some of the other bikes but, more often than not, they were broken and out of order, even the ones at my physical therapist. That fact sent me to look seriously at the M3i. Ultimately, the smoothness, the adjustability, the silence, the comfort, the simplicity, the durability, and the good looks of the...

I like the M3i bike, but the handlebars are uncomfortable for long-rides

I love the bike, it's silent, easy to operate and Bluetooth easily connects to Trainer Road app which is what I use daily. My only gripe is the handlebars. They are uncomfortable for anything longer than 30 min ride. My wife and I both use the bike and both agree that replicating road-bike ride with these handlebars is useless and uncomfortable. I wish Keiser offered an option/upgrade for true road bike handlebars for those that want to use the M3i for indoor winter training without having to purchase more expensive bike trainers. I may end up selling the M3i and replace it with something more suited for road bike training.

Keiser Responded:

Hi Alessandro,

Interesting! I've not heard of this before, can you shoot me an email or post a response here with more information on the difficulty? The M3i handlebars are super adjustable and that always contributes to a comfortable ride, I'm curious as to which grip styles you are having issue with.

Thank you,

Great of folks with A-Fib

VERIFIED PURCHASE
This review is aimed at people like me, who have atrial fibrillation, and are wondering whether or not this stationary bicycle is suitable for them. In two words – absolutely yes. I am a seventy-three year old male with a BMI north of thirty. I cannot feel the arrhythmia directly but rather the side effects – primarily light headedness and lack of energy.
I’ve owned a Keiser M3i for fourteen months. Being a Type A person, I decided to push myself with high intensity interval training. I gradually increased the gearing so that my heart rate was in the low to mid 130s at the end of the session. I use shoe clips so my feet are well anchored to the pedals. One day I experienced significant light headedness and decided that fainting on the bike was not the wisest of plans, so I...

I’ve owned a Keiser M3i for fourteen months. Being a Type A person, I decided to push myself with high intensity interval training. I gradually increased the gearing so that my heart rate was in the low to mid 130s at the end of the session. I use shoe clips so my feet are well anchored to the pedals. One day I experienced significant light headedness and decided that fainting on the bike was not the wisest of plans, so I modified my routine.
Instead of shooting for a maximum heart rate in the 130s I lowered the gearing so that I peaked out at 110, or below. That was several months ago and I haven’t had any A-Fib symptoms on the bike since then.
As part of the process of lowering my peak heart rate on the bike I discovered something that was counter-intuitive. The bike aggregates your session and presents averages when you are done. My initial sessions resulted in an average heart rate of about 105, a “Trip” of 4.6 and distance of between 10 and 11 miles. Using the same timing, but reducing the gear on the high intensity portions has resulted in average heart rates in the mid to high 80s, a “Trip” of 4.5 and distance of between 10 and 11 miles. In other words, assuming the “Trip” figure accurately represents the energy expended in the workout, I’m now getting virtually the same workout with far less stress on my heart.
For whatever it may be worth, I use an interval timer app and stream music to my earbuds during the ride. Life is good.

love the M3i bike

VERIFIED PURCHASE
I went back and forth on which spinning bike to pick up for the winter months and landed on the M3i. Feel like I made the right choice, the biggest thing I was looking for was a realistic riding feel, easy way to change resistance, and way to connect with some of the biking apps out there (like zwift).

The bike is wonderful, the converter not so much

VERIFIED PURCHASE
The bike was relatively easy to put together (especially after watching the youtube video.) The bike is solid and smooth. The converter technology is clunky and really needs an upgrade. Opening and closing the converter to get it it to pair is unacceptable given today's technology. It took several tries to upgrade the firmware of the converter and finally it is updated and using the always on. I assume this will drain the battery quickly though. If the converter technology was improved and it used any bluethooth HRM it would be the perfect bike setup.

Keiser Responded:

Hey Cyn, thanks for your review, I'm sorry to hear you got a troublesome Converter! Most Converters do not require the firmware update, nor the troubleshooting step of opening and closing to get it to pair.

Thanks again, and I am at least happy to hear the bike itself is treating you well.

Best,

Best investment in my health!

VERIFIED PURCHASE
I used to use the Keiser bike at my gym, and am so glad that I invested in one for my home. It helps with my knee rehab, and is a logical addition for a home gym.
