excellent bike

VERIFIED PURCHASE
Quiet, adjustable and really well made. The app / info tracking / training experience is a bit off; they'd do better partnering with others. But the bike is the main thing and it's hard to find fault with such a great experience.

Keiser Responded:

Great points Phil, we're actually in the process of several improvements to our digital experience, including the Keiser M Series app.

Stay tuned!

Great product...however disappointing customer service

Keiser's customer service has left a lot to be desired. I am Highly disappointed about the overall process. I ordered the con
Bike, added the assembly tools and the converter. Well, 2 months in, and multiple calls later, I still haven't received the converter. There has been inconsistencies regarding whereabouts of converter- one person told me it was on backorder and another said that they forgot to include it in the shipment. At this point, I don't know if I was worth spending the extra money for the converter.

Now, regarding the bike itself- I had a pretty good idea what to expect because as a gym/spin enthusiast, I am familiar with Keiser bikes (older models). Nonetheless I took the time to research and compare other popular bikes within same class, and I decided on the Keiser M3i because of the value...

Now, regarding the bike itself- I had a pretty good idea what to expect because as a gym/spin enthusiast, I am familiar with Keiser bikes (older models). Nonetheless I took the time to research and compare other popular bikes within same class, and I decided on the Keiser M3i because of the value and knowledge that s a reputable brand,Keiser bikes deliver. It is perfectly designed and not too bulky. It is sleek, smooth and reasonably quiet. Assembly was not difficult (according to my husband) and he found the assembly video to be helpful. Now that I am waiting to receive converter, I am starting to wonder whether converter is worth the investment and adds any extra perk to the bike. I just wished that shipping included ALL ordered components.

Keiser Responded:

Hi Natacha,

I'm sorry about that, we abruptly ran out of stock of the M Series Converter due to COVID-19; the company that we worked with on their production had to send all of their employees home and it was just the owner operating alone. We removed the M Series Converter from our website as soon as we ran dry, however some customers were affected by the shortage and I do apologize for that.

Converters are back in stock and we're operating at full capacity for the time being! I'm glad you're enjoying your cycle other than the difficulties with the original shipment.

Best,

Best indoor cycling bike ever!

VERIFIED PURCHASE
Very smooth and quiet ride. I love this bike! Keiser is also what I was used to at my gym, which is where I first learned about it. With the polar strap that it comes with, I can track my heart rate and see my calories burned and I’m able to set my goals with the app. Well worth the money!
