Works well; difficult to assemble; some play in the frame

VERIFIED PURCHASE
I like the bike a lot, and I use it a lot. I'm only giving it three stars, because I expected a bit more for the price.

I like the solidity of the pedals. I like the magnetic gearing and the gear lever. I like the media tray. I like the overall quiet operation of the bike, once I resolved a creaking sound (see below).

Assembly was more difficult than I thought it would be. I feel like there should be a more fool-proof method for customers to assemble the unit without scratching the flywheel. I managed to scratch mine while I was attempting to tighten the screws with a metal allen wrench. Allens have a tendency to pop out sometimes, which is what mine did, and the allen brushed against the flywheel and scratched it. Not the end of the world.

The bike creaked initially while pedaling. It seemed that the noise was coming from the exterior plastic, so I tightened some (factory-installed) screws down, and the sound went away.

I feel like there is more play in the handlebars than I would like. I would like the handlebars to be rock solid, but there is a little bit of give to them.

The handlebars are set up for fully leaning forward. I would prefer them a little closer than I am able to achieve by adjusting the seat and handlebars. (I'm 6' tall.)

I do enjoy the bike. I tend to watch movies on an iPad while riding. I don't do a lot of stand-up cycling - typically only when I need a change of position.

Paul,

Thanks for the feedback, installing the flywheel can be a tricky part of assembly, we include a foam sheet with the flywheel to help safeguard it during installation.

The Keiser M3i is classified as an "indoor cycle," different than an "upright cycle" which have a much more upright ride position. I imagine it'll feel more natural over time, the user manual has information on how to size the cycle appropriately to reduce discomfort even in those who are used to a more upright position.

All the best,

Great bike

VERIFIED PURCHASE
I liked my 1st so much I bought a 2nd for a 2nd residence. A little disconcerting because the 2 bikes differ markedly in pedaling resistance for a given gear/watts. I really like the youtube cycling video "Pure" by Buddy--30 min, I extend it to 45 with extended warm ups and cool downs.

Keiser responded:

Andy,

We get that a lot, and it's true: older bikes will feel and perform differently as compared to new bikes for several reasons. I would want to compare your two bikes before making any kind of specific claim to what could be the culprit though! If you give us a call or send an email to service@keiser.com we'll troubleshoot with you and see if we can't figure something out. I'd want to know if the models are the same (M3 to M3, or, M3i to M3i) and what year the cycles were manufactured.

Thank you!

High Performance/ Quality Superb

VERIFIED PURCHASE
This bike is so smooth and quiet. It gives a high intensity workout! We did a lot of research before purchasing and almost went with one that had the built on monitor. I am so glad I did more research. We use our tablet or tv as a monitor and have so many apps to choose from. One of my favorites is BitGym. Dont let the monitor be your deciding factor. This bike kicks a**! 💯% satisfied! 🥇

Too much of a good thing

VERIFIED PURCHASE
Unfortunately I road a little too often and too hard initially. I’m 69 and ended up straining a quadriceps muscle. I’m just about recovered now and am taking it easier on the workouts till I build up a better tolerance for most difficult workouts. I really like how quiet it operates and that the flywheel is behind the sweat zone. My wife and I also bought one for one of our daughters and her husband as they are bike fans. Mike Douglas helped with that purchase. Thanks, Mike!

Sure thing Jim!

Excellent bike

VERIFIED PURCHASE
I'm very happy I decided to purchase this bike. It is well made, it fits my 5'2" body size, it is so quiet and smooth, but most of all I love that the gear shifter is a lever at the handle bar and that it changes gear instantaneously. The only suggestion I would recommend is making the water bottle holder somehow clasp in because I always forget about it and then I kick it off when I get off the bike at the end of the workout. But it's a minor inconvenience.

Excellent Indoor Bike

VERIFIED PURCHASE
I've had my M3i for a few months and I'm completely satisfied with it. It was shipped promptly and arrived on time, and intact. The materials and craftsmanship are excellent and worth the cost. At the time of my order, the assembly and maintenance kit was included. Assembly was straightforward and can be performed by anyone with basic mechanical skills with common hand tools. The bike is light enough for easy maneuvering into whatever space you have. For the last 9wks I've been riding 5 days a week for 30-40 minutes each session. The M3i is very smooth and feels like pedaling my mountain bikes. The magnetic resistance is very smooth and offers a lot of range. As well, the bike is whisper quiet. Overall I am very pleased with the M3i and completely satisfied with my purchase.
