LOVE THIS BIKE!

VERIFIED PURCHASE
I finally replaced my old M3...after 13 years! And no, the M3 didn't stop working. I'm giving it to a friend, which gave me an excuse to upgrade to the M3i. After lots of research, I realized that I needed to find an excuse NOT to stay with Keiser. Simply put, the M3i in an incredible indoor bike! It retains ALL of the things that made the original M3 the best bike on the market and adds just enough new features to keep the platform current. The bike is ridiculously stable and simulates outdoor riding better than any bike on the market. It's a gym-quality machine, so it's designed for LOTS of use without any degradation in performance or the need for complex maintenance. Great instructions make assembly very easy (as long as you actually READ the instructions). Given the price, performance, simplicity of design and durability, the M3i...

Great instructions make assembly very easy (as long as you actually READ the instructions). Given the price, performance, simplicity of design and durability, the M3i offers an incredible return on investment PLUS the freedom to use any (or none) of the fitness platforms on today's market. This eliminates any concerns you might have about getting locked into one fitness platform in an expanding market of options. If you're willing to spend this much on an indoor bike, the M3i is the one to get. And if you're trying to convince yourself to spend this much on an indoor bike, the M3i is worth the investment several times over!

Thank you for your comments Tony! It's always a joy to hear from customers who really enjoy and get great use out of our products.

Wishing you many happy years with your M3i!

I love this bike!

A great way to exercise at home - and to exercise hard! I set it up by myself - super easy and doable and I’m not super handy - in little time. Now I’ve been doing on-demand spin classes every day. I would highly recommend this bike. I’ve tried other models but the frame on the Keiser feels more substantial and sturdy and the placement of the wheel is best for a hard-core workout compared to other brands.

Long legs, shirt arms and torso

The mechanics and styling are 5 stars.

Due to my body geometry, when I get the seat height and position set I am seriously stretching forward and down to use the handlebars. I sure wish there were handlebar geometry options.

Keiser responded:

Thanks for your feedback MGB, are you bringing the handlebars in as close as they can go? Our M3i handlebars can adjust forward and backward and generally accommodates riders up to 7' tall. I recommend you watch our bike fit video and compare it to your setup, sometimes that can help!

Best,

Love this indoor bicycle!

VERIFIED PURCHASE
I have a strong background as a cyclist including road racing both USA Cycling and ultramarathon plus taught spinning for 3 years. Replicating my road bike fit was easy, it rides smoothly, and it is quiet. The media holder works well and I cannot think of anything to change. And it is nice not having to: change flats, fall off of rollers (I’m getting old), and sweat on my road bikes.

Fantastic quality and entirely worth the price

VERIFIED PURCHASE
I did a lot of research trying to find the ideal exercise bike for home use that would be good quality and have the features we needed. After a lot of research I landed on the M3I and I’m really glad I did. The build quality is fantastic and took about an hour or so to put together. I definitely recommend getting the tool kit—without it it would be a bit more challenging as we didn’t have all the proper tools. The bike is whisper quiet when we ride, and the adjustability is great. It fits my wife, who is 5’2”, very comfortably and I can easily adjust up to my height when I go to ride.

I also really appreciated that the instruction booklet gave tips on proper riding positions as well. It’s been incredibly helpful, especially for first-time riders like us.

We also got the gel...

We also got the gel seat cover which makes the longer rides less uncomfortable, and is better quality than a few we tried from other retailers.

Overall if you’re looking for a quality bike that will last for years, and one that won’t lock you into a specific workout ecosystem, I highly recommend getting this bike.

Excellent indoor spin

VERIFIED PURCHASE
I'm currently only ramping up time and resistance while I work through a sciatica injury but this bike is great. After 40 years of road riding, I wanted an indoor bike offering the feel of a road bike WITH a gear indicator to use as a reference when comparing day to day effort. You can tell it's solid product in design and build quality.

Right from the unboxing it was easy to see the quality of the M3i. Great support staff too.
