“My 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.

VERIFIED PURCHASE
Searched the web a long time before deciding on a purchase.What sold me was, Made in the
USA. Quality build. Support after purchase. Read many reviews on other bikes and narrowed it
down to two. The reason for choosing Keiser M3i was the aforementioned highlighting support, other bike support was lacking real concern and following through till problem solved.

Great Bike

VERIFIED PURCHASE
We just bought a vacation home and so we bought another Keiser M3i. Now we have two. We love it. Exceedingly smooth. Better adjustability than that other national brand. Of all the bikes available- this is the best.

So quiet and easy to ride

VERIFIED PURCHASE
We are avid road bikers and bought this bike to stay fit when the weather keeps us indoors. It is so well constructed and easy to adjust that we both look forward to our sessions on it. It rides incredibly smoothly and is nearly noiseless - the person in the next room can’t hear it at all.

Great bike! Very happy with purchase.

VERIFIED PURCHASE
I was first introduced to Keiser bikes at my local box gym. There, they have M3's -- when I'm not able to get on my road bike due to weather, the M3 was a great alternative. I decided I wanted to invest in my health and get a M3i for my home. The M3 didn't have the ability to adjust the handlebar positioning which made them slightly uncomfortable for me on longer rides. The M3i completely solves that and allows for a much more comfortable ride. I'm horrible at putting stuff together, but with the YouTube video along with the well-explained installation guide, I was able to assemble on my own. Very happy with the purchase and have been using it daily! Love the convenience of being able to just hop on whenever I want to.
