Useless since it does not connect to any training app on the market

VERIFIED PURCHASE
TrainerRoad, Sufferfest, Training Peak, Zwift, forget about it. You have a Keiser M3i and Keiser decided that you have to write your training plan on a piece of paper and put it in front of the bike in order to keet track of your workout. Great mechanical engineering, complete lack of market knowledge. Bike is good but useless. Save your money for Peloton bike, Wahoo, etc.
Oh, they have the converter, the most expensive gadget ever. Treat customers as fools, the Keiser way.

MONEY WELL SPENT

VERIFIED PURCHASE
I have been using my M3i spin bike for about two weeks. It was very easy to assemble-watching the video was extremly helpful. I exchanged the pedals and seat for my own set of SPD pedals and a seat with a cutout so its a much more comfortable ride. I also purchased the bluetooth converter, which I use with the Peleton app to stream spin classes whenever it is convenient for my schedule! Everything pairs together seemlessly. It is a gym quality spin bike-in fact, I think it's better. It's solid and quiet. However, If you pair your Keiser bike with the Peleton app, download the resistance conversion chart as Peleton and Keiser resistance stats are very different. I purchased this spin bike for a couple of reasons-to improve my CV fitness, reduce my blood pressure, and lose weight. I have...

I purchased this spin bike for a couple of reasons-to improve my CV fitness, reduce my blood pressure, and lose weight. I have already seen an improvment in by blood pressure which is most likely due to consistent exercise and loosing a few pounds. Yes, it is a big financial investment but I think my health is worth it!

Road feel, gym/home location

VERIFIED PURCHASE
This spin bike gives you the feel of a road ride. It's smooth, quiet and mimics a real road bike. The adjustable seat post, seat location and handle bar lets you get the best fit.


The resistance is adjustable and allows you to push through "hills" or spin fast while you "sprint".

It's easy to assemble. I was able to do it by myself, though it was fairly heavy.

The app connects seamlessly on my tablet and the FTP test is a great way to track your progress. There are some guided workouts but I tend to follow programs I've found online and adjust for my needs.

exercise at last

VERIFIED PURCHASE
Due to COVID, many of us have been displaced from our norms. After a few months of doing all home exercises known to man; I decided to purchase the Keizer spin bike. I enjoyed my past spin classes and not sure when that is going to be okay to start up again so took matters into my own hands. This is a great bike and would recommend it. Solid, quiet, doesn't take up a bunch of room, clean lines and runs like a dream. Its a well made bike. Once ordered received it within about 7-10 working days. Financing and purchase process very easy.
