Sturdy bike and incredible customer support

I purchase an M3 second hand a couple of years ago. Recently I had an issue with the computer. I reached out to customer support and received very quick and effective feedback to solve my problem.

Beautiful bike, but not quite worth the pric

VERIFIED PURCHASE
I wanted to ride my M3 at least a dozen times before reviewing it. Overall, it is a solid bike made from quality materials. I was excited to buy something American-made.

The handlebars were an absolute pain in the rear to install. It took me hours to get it right. You have to get them in just the right place and lean them at just the right angle because the screws do NOT want to fit in. I finally found a video from a random YouTuber showing how to get the handlebars just right. The rest of the assembly was ok with the instructions provided. If I could do it again, I would pay the extra $ to have a professional install it.

I do have to tighten the handlebar screws every few times I ride it. I also had one of the screws from...

I do have to tighten the handlebar screws every few times I ride it. I also had one of the screws from the hubcap fly off during a workout (easy fix, but still). At this price point, I expect things to not be falling off or coming loose.

I think most people would do well to purchase cheaper bike, and I am not convinced the M3 is worth what I paid for it.

Keiser responded:

Thanks Amber,


I'm surprised to hear that you need to tighten the handlebar screws so frequently, particularly if the correct torque is applied. Please contact our service department if you continue to encounter this issue because you're 100% right; you should not need to tighten or adjust the screws so frequently.


Thank you for your review,

Love the M3!

VERIFIED PURCHASE
The M3 is a great addition to my home exercise equipment. Fortunate to have had the opportunity to train on the M3 before my purchase. Worked at training academy and they had plenty of M3's to ride. I like that its heavy but very solid/stable when your riding hard with no wobble. Its very quite and the peddling has the same precision like being on my road bike.
re my mention of it being heavy, the 2 wheels on the front of the frame make it easy to move around my home.
