The Keiser Bike is very well designed and engineered

VERIFIED PURCHASE
The Keiser Bike is a delight to ride. Its design is adaptable to any size rider. My 6'-8" frame is easily accommodated, as is my wife's 5'-6" frame, and thus the ride is smooth and comfortable. Assembly and calibration was straight forward and easily accomplished.

Keiser responded:

Thanks for your comments Peter!

Our V-shaped frame combined with the fully adjustable handlebars on our M3i make for an incredibly versatile set up, glad to hear it works for the both of you.

Best,

Very dissatisfied

VERIFIED PURCHASE
Called in for some zwift advice question and calibration question got treated terrible and passed around, I let them know the issue and they said to call back after a few rides, worst treatment after paying 2k for m3i...

Hello Jeremy,

I'm sorry for the run around, when diagnosing an issue with the cycle we occasionally will need to send you to multiple departments to get to the bottom of things. For example, a Zwift connection issue might be better served by our software engineer than our service department, depending on the nature of the issue.

Our service team will recommend for certain issues that you ride the cycle a few more times to assist in troubleshooting the problem. Some cycles go through a more pronounced settling period than others and there might be some noise or an odd bump here or there that work itself out as the cycle "settles" to it's final configuration. If the problem persisted after the trial period, it narrows the focus of our service and helps to expedite your service. From the sound if it though, this could have been better communicated,...

Better than Expected

VERIFIED PURCHASE
I was sold on purchasing an indoor exercise bike after using a friends Peloton. On one hand, I didn't want to be locked into the monthly fees, but on the other hand, it's a solid piece of equipment and I liked having the computer feedback of resistance level, output, etc. After doing a ton of research, I decided on the Keiser. And even though the reviews I read were glowing, I was still skeptical that it would match the Peloton for quality, and that I would be satisfied with its monitor.

Well I'm happy to say that I my skepticism was unwarranted! I would still like to see an upgraded computer monitor, but other than that the bike is almost perfect...better than I expected!!

Best Fit For My Requirements

VERIFIED PURCHASE
As an avid cyclist, both on the road and on single track, I was looking for a convenient and viable alternative to riding stationary bikes at the gym, while enduring the snow and cold winter months in Colorado. After extensive online research, I decided that the Keiser M3i was the best fit for me.

Based on the many positive reviews, I placed my order shortly thereafter. sight unseen. The online ordering process was quick and easy. The shipping was delayed a bit due to the Christmas backlog. My bike was number 132 built on 3 Jan 19.

When it arrived a few days later, the box was laying on its side when the FedEx delivery truck rear door was opened. The driver said it kept falling over during his route. Despite my pointing out the This Side Up on the box, he turned it end over...
As an avid cyclist, both on the road and on single track, I was looking for a convenient and viable alternative to riding stationary bikes at the gym, while enduring the snow and cold winter months in Colorado. After extensive online research, I decided that the Keiser M3i was the best fit for me.

Based on the many positive reviews, I placed my order shortly thereafter. sight unseen. The online ordering process was quick and easy. The shipping was delayed a bit due to the Christmas backlog. My bike was number 132 built on 3 Jan 19.

When it arrived a few days later, the box was laying on its side when the FedEx delivery truck rear door was opened. The driver said it kept falling over during his route. Despite my pointing out the This Side Up on the box, he turned it end over end while unloading it. The outer box showed some minor damage, but the inner box looked fine. The core bike assembly and parts were well packaged with plenty of protective foam and shrink-wrap. It should be noted that care should be taken not to allow the base and handlebars to fall during removal of the shrink-wrap. Only visible damage noted was to the foam packing block protecting the handlebar down tube.

Found that it helped to view the Keiser assembly video a few times for familiarization before the bike was delivered. However, it was easier to use the included detailed, well illustrated manual for actual assembly. The included Craftsman tool kit was much appreciated. Actual assembly was simple, very easy and enjoyable. Only minor difficulty encountered was properly tightening the two upper handlebar slide mounting 8mm screws due to the depth of the slide. Used a pair of pliers to gripe the short end of the provided Allen wrench which did the job. A few minor cosmetic scrapes and marks were noticed on the beautiful aluminum flywheel and crank pulley surfaces.

Once assembled I found the bike very easy to move. The small footprint doesn’t take up a lot of room. Adjusting the saddle and handlebar positions to properly fit my 5’7” frame was simple and intuitive. The handlebars offer multiple hand positions while riding in/out of the saddle. Encountered zero problems using the SPD side of the pedal with Sidi shoes. The shifting is fairly precise and consistent; much better and more practical than randomly adjusting a flywheel pad knob. Pairing the Keiser M Series app to my iPhone X with the bike’s computer was quick and seamless. Pedaling is smooth and relatively quiet.

In the beginning I detected a slight clicking noise while pedaling at slower rpms. I contacted tech support about the issue and emailed a video of the noise per their request. Was advised a few days later that it was the drive belt and sounded normal to them. Wouldn’t think a belt would be the cause of a clicking noise. Anyway, time will tell whether or not it will be a problem in the future. Another minor niggle deals with the Keiser M Series app. It records speed/distance on the summary screen, but fails to upload it to Strava less than 50% of the time using the generated .pcx file.

As fine of a machine as the M3i is, I have a couple suggestions I’d like to present. First, put detents in the shifting lever action to engage accurate gear selection consistently. Currently, it’s kind of hit and miss engaging the proper gear. Second, why not make the bike available at a lower base cost without including a standard saddle and pedals? Make them optional purchases. Riders could use their own preferred road/mountain bike saddles and pedals without paying for saddles and pedals that wont be used.

As a retired aerospace engineer, I can appreciate the modernistic design and quality of engineering of the M3i. The manufactured components and initial assembly appear excellent in general, as does the fit and finish (photo). Kudos to all at Keiser who make such a wonderful machine available.
