Love this bike!

VERIFIED PURCHASE
Not short in duration, this bike was super easy to put together. Pretty small footprint, too. Will fit well in my tiny home. This is a great bike!!! I've ridden many other Keiser bikes at the gym (and loved them), so I'm very excited to have this one in my home.

Amazing piece of equipment

VERIFIED PURCHASE
This spin bike is so amazing. It is so smooth, quiet, and can be adjusted in so many ways I haven't even found them all. We had some trouble getting it delivered by Fed Ex but the company was so responsive. Quality, good price and a company that cares about it's customers-you can't beat it.

Well Built, Quite Ride for an Excellent Workout

VERIFIED PURCHASE
I have used this bike for about 3 weeks now. The assembly was easy but took a couple hours. Once assembled this is a solid, well built bike that is very quiet to ride. I pair my Keiser M3i with the Peloton App on my iPad to keep me motivated and for an excellent Covid19 socially distanced workout.

This thing is great

VERIFIED PURCHASE
Very happy with this well engineered and constructed bike. Manual is well written and informative. Packaging was excellent and withstood the FedEx treatment. Money well spent. Only issue at all was it took a few minutes to realize the batteries all needed to be replaced.

Very pleased so far

VERIFIED PURCHASE
I purchased the M3i, the M series converter, and the M series assembly and maintenance kit. Firstly, the bike and accessories were packaged very well, and very securely. The oodles of shrink wrap, while providing excellent protection, were a bit of a chore to get through. I found the installation instruction pamphlet overall very easy to follow, and together with my wife, we put the bike together in about 1.5 h end-to-end. We took our time to carefully inventory parts, and to carefully read and understand the instructions. There were a few steps that tripped us up a bit, but by studying the parts, we were able to sort without issue. Note that we are not terribly handy. The toolkit was a big help. Pairing the M series converter with the bike computer was a bit tricky--had to read the instructions twice--but not overly difficult. One recommendation for Keiser is...

Pairing the M series converter with the bike computer was a bit tricky--had to read the instructions twice--but not overly difficult. One recommendation for Keiser is to provide an instruction pamphlet with the converter with much larger font. Even with my glasses, some words were nearly impossible to read without a magnifying glass (I have 2.75 diopter correction). I was able to very easily pair the converter with my iPad, and pairing with Zwift app was a snap. I am an avid cyclist looking for a good indoor alternative during the winter--and to avoid gyms. My first two 25 mile rides were excellent. Really smooth ride, and was able to get a very intense workout, including intervals. Gears of 16 and higher emulate hill climbs nicely, and shifting between gears is a sinch. The pairing with Zwift is for the most part good, have yet to try with Sufferfest. I have one other recommendation for Keiser. Please consider providing an alternate pedal set with SPD-SL clips for those of use coming from the road cycling world. For now I am using the cages, but have order a set of SPD-SL pedals so that I can use my existing kit. Overall I am very pleased so far, and impressed with the simplicity and quality of the bike.

As great as expected

VERIFIED PURCHASE
I taught indoor cycling classes at my health club for a number of years, and I knew Keiser bikes had a great reputation for durability. That was the deciding factor for me, even though it was a little more expensive than similar bikes. Until I received mine, I hadn't actually used an M3i, but it is great. The improvements in design show thought and learning from earlier versions. It works great -- it gives a very smooth ride, and the geometry allows me to keep the right form in and out of the saddle. It's only been a little over a week, and I've already had some great rides.
