Nice overall, seat could be better and RPM / Power Fluctuate a lot

VERIFIED PURCHASE
Have used M3i bikes in a few spin studios, and really like the quiet and smooth operation. The seat seems to be a bit on the cheap side for what the bike is, budget for replacing it if you intend to spend a lot of time on the bike. Also, not sure if it is something specific to the bike I got or overall setup has changed - but the RPMs and power reading jumps around a LOT. This was not something I experienced using these bikes at a spin studio, thus was a surprise here. Seems like it holds pretty steady at low RPMs ~80 and below, but as most spinning is done at 90+ RPM - its annoying that the numbers jump around.

R U a Spinner?

VERIFIED PURCHASE
This bike is impeccably engineered . Easily adjusted and so quiet. My cat even gives it her sign of approval. I had experienced this bike at my squash club so knew what I was getting. I spin at home now with online classes and strongly recommend this product pandemic or not.

Better than a Peloton

VERIFIED PURCHASE
This bike is top of the line! Couldn’t love it more. I was supposed to get a peloton but they had issues with their delivery process, it was supposed to be delivered in 4 weeks then they missed that delivery date and it wasn’t going to be for over 13weeks. Me being impatient did my research and discovered Keiser through a cycling community. I compared the two by trying my friends Peloton, I am so happy with Keiser and it came within 1 week.

Fantastic Bike!

VERIFIED PURCHASE
Bought as a Christmas gift for my wife and I. Already several rides and I'm loving the bike completely. Extremely well packaged, great instructions, easy assembly, and every bit the quality of construction I expected-- top drawer!

Better than expected

VERIFIED PURCHASE
The bike arrived in perfect condition and straight forward to put together. The bike is as expected (ridden at local gym) but in better condition.

Great quality bike but not so great integrating to Apple Watch

VERIFIED PURCHASE
We chose this bike in December 2020 instead of the Peloton bike because we did not want to be captive to a single fitness provider and still use my Apple Watch's HR monitor. I don't like HR bands anymore. Reading reviews I knew in advance that I was buying great quality equipment and I did get it from Keiser. My son almost had an accident yesterday trying to play with the pedals at the same second that I wasn't looking at him... since M3i does not have a free wheel the pedals keep rotating with the inertia and he almost got hurt... But that is not my main concern. My main issue is with the bluetooth 'computer' display. It looks like technology of the '90s but it was supposed to work flawlessly with Strava, Apple fitness and Peloton. In the Peloton app I only get Cadence but that is...

In the Peloton app I only get Cadence but that is not Keiser's fault but Peloton's and my fault for not knowing. When using the M Series App I get a lot of data but not Apple Watch HR. When using Apple Fitness I get heart rate but not Cadence. Finally in Strava I get all the needed Keiser data what is great but Strava's Apple Watch HR sometimes loads, sometimes shows wrong data and sometimes it does't load at all... In summary, I still don't have what I need. If the M series App had Apple watch integration I has very little complaints.

Great bike, great service

VERIFIED PURCHASE
I've had my new M3i for about three weeks now and really enjoy working out on it. The bike is solid, stable, and very sturdily built. Even at maximum effort it is very quiet. I have no doubt it will last for many years to come. I did have a small problem with the M Series Converter I received with the bike but am pleased to say that Keiser overnighted a replacement as soon as I contacted them. All around, a great experience!
