“Ny son is 6'10’ and a college athlete so we needed a durable bike that would adjust to fit his height. This bike was perfect. I love that we can easily adjust both the seat and handle bars to give everyone in our family a perfect fit. ”

THE M SERIES PEDAL

Workout shoes or SPD cleats

Use your favorite standard workout shoes with the built-in toe clip straps on the M3i. Or, flip the pedal over to use your favorite cycling shoes with popular SPD cleats. To use another cleat style, simply replace the pedals with your choice of standard bike pedals (9/16" x 20 TPI) that accept your desired cleat.

THE M SERIES SADDLE

Find your comfort zone

The M3i comes with a saddle that provides a classic road bike experience for a wide variety of riders.

We designed our adjustable seat mount to fit all standard bike saddles. This gives you the option to add your choice of saddle for that truly perfect fit.

If all you want is a little more cushion, you can easily add a comfort seat cover to the saddle that comes with the 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.

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.
