The Keiser bike is the Rolls-Royce among indoor bikes. Period!

VERIFIED PURCHASE
I am a spinning instructor at two well-known health facilities. One club has a bike that I cannot mention the name and the other health club (LA Fitness) has the M3i Keiser bike. I have been teaching on the Keiser bike for more than five years and I absolutely love it. Because of Covid 19, I had to limit my time at the gym; so I purchase the M3i for my personal use. I'm in heaven!!!

Almost Perfect

VERIFIED PURCHASE
My wife and I replaced our tri bikes and trainer units with the M3i bike for indoor training. Wow very quiet, smooth and comfortable. Only complaint is the display unit. Once you stop pedaling you have only 60 seconds to start pedaling again or the display resets everything back to zero. Soo annoying if you need to stop workout to get water or a bathroom break. Wish they would provide a software update to fix it. If they fixed that I'd definitely give it five stars. Everything else- delivery, quality, design was superb.

Dave,

You can actually use the Keiser M Series app to record your exercise sessions on any of our Bluetooth enabled products! That way if you need to get up, it will store all of your data from your first session.

Thanks for your feedback,

Great Quality and Functionality

VERIFIED PURCHASE
I purchased this Christmas special directly from Keiser. It took about a week to prepare shipment and then just 2 days to arrive - kudos to FedEx! Considering pandemic impact on supply chains and transportation, this was really fast.
As far as assembly it was really easy. The only point I was a bit uneasy was looping and squeezing computer cable into its bracket. Other than that, no issues.
Bike works great. It is smooth and quiet. I really prefer the feel of M3i with its light flywheel over my previous spinner with 49 lb flywheel. Keiser gives me more realistic feel of real biking pedal strokes. Maybe this is because I am a mountain biker, not a roadie.
I am not a fan of training apps, so I am fully satisfied with basic functionality and manual controls. I use M Series App and integrate with Strava to record...

I contacted Keiser before and after my purchase and they were responsive and helpful. All in all, just one month since its arrival, I like my Keiser M3i very much.

Polar battery 🔋 Dead: heart rate monitor

VERIFIED PURCHASE
The brand new indoor bike is great but one thing that disappoints me is that the polar heart rate strap doesn’t work because the battery seems to be dead. Can you send me a new one since this is supposed to work upon arrival.?

Solid Choice

VERIFIED PURCHASE
My wife and I are happy with the M3i. Very quiet ride. Solid and sturdy feel. We had an issue with the LCD screen antenna not keeping a solid connection with the H1 heart rate monitor and customer support quickly sent a new LCD. After installation the connection with the H1 heart rate monitor is as expected. The only two knocks on the M3i that we have are:
(1) the M3i shows my heart rate (via the H1) to be about 90 BPM faster than what my Garmin 245 Forerunner watch and my wife's Fitbit show. When the two watches show my heart beat to be about 80-90 BPM the M3i says its 170 BPM, which I know isn't correct;
(2) I keep knocking my water bottle onto the floor when getting off the bike. I wish the M3i had a...

We love our new bike!

VERIFIED PURCHASE
I used to ride on a Keiser M3i at my gym's cycling classes. Once the pandemic hit, I was missing cycling. After shopping around and comparing the Keiser to other bikes, I knew that the Keiser was the best decision. It arrived quickly and although assembly took quite a bit longer than I expected, it was really easy to do. My husband and I both use the bike for Peleton Digital classes. We absolutely love it and believe this bike is better than a Peleton. I highly recommend this to anyone!

best indoor bike

VERIFIED PURCHASE
i have taught indoor cycling for over 7 years on a variety of bikes and by far the keiser is the most solid and versatile. it is very user friendly in it's adjustments and read out even for a beginner cyclist. ergonomically designed to adjust to any body and the gauge gives you all the information you need.
