Holiday bundle is not working on the website

VERIFIED PURCHASE
I am trying to make a holiday bundle purchase and the site keeps telling me my cart is empty when I try to check out. Please contact me so I can buy an M3i for Christmas. Sorry for the one star. I'll be sure to correct it once I get the purchase to work.

Stop shopping around!

VERIFIED PURCHASE
Hands down, this is the bike you should buy. The quality cannot be matched. This product is made in the USA! I was nervous about putting the bike together myself but the instructions are very clear and the tools are easy to use. This replaces a purchase I regret - it is always true, you get what you pay for! Remember, you can use this bike with any app. The other bikes cannot claim the same thing.

Excellent Quality Spin Bike

VERIFIED PURCHASE
My gym used these in our spin class so I knew they were rugged and could take a lot of abuse. It rides very smoothly right out of the box.

Graduated up to an excellent bike

VERIFIED PURCHASE
Started spinning at home three years ago with a trainer on my old road bike. Since then, I’ve had an used StarTrac Spinner and a new Spin L3, they all pale in comparison to the build quality, ergonomics, and well-thought design of this fitness machine.

American 🇺🇸 Made Quality Bike that outperforms the Chinese made Peloton hunk of junk.

VERIFIED PURCHASE
The quality engineering that went into this bike is evident the minute you open the box. Every detail was thought out right down to the care they took in the packaging. The M3i is extremely well made.

I’ve ridden a Peloton at the gym for years and almost bought one until I learned about Keiser. The more I researched, I realized that Peloton’s success is due to their marketing. Keiser is the better bike by leaps and bounds. If you are looking for an enjoyable riding experience, this bike will fit the bill better than Peloton.

I am so proud to have purchased this bike and to support the American employees of this company who are passionate about making the best bike.

Thank you, Keiser, for employing people who are passionate about producing the best quality product.

I'm really happy with this bike

VERIFIED PURCHASE
It took 2 hours to assemble it, but the directions were very clear. I needed a lot of different tools, but I already had them. It's a great performer- I love it. I'm really pleased that I bought it. I was confident in my selection because I had been riding these at my gym. The computer with cadence and time is a bonus. The adjustment range is broad, and works for me, but I question whether it would work for someone under 5'4. It replaces a 30 year old Turbo trainer.

Best Indoor Exercise Bike

VERIFIED PURCHASE
I have been bicycling for over 35 years and during that time I have owned numerous indoor exercise bikes for the cold months when biking outdoors is not possible. And without a doubt this is the very best indoor exercise bike I have ever owned, it is not even a close call. Plus I am not the most mechanically inclined person and I had no difficulty assembling it by myself. The only possible problem you might encounter trying to assemble this on your own is if you are very old, it might be a challenge unpacking and setting it up because of the weight. I am in my mid 60s and was able to do this with very little problems. Plus I also purchased the tool kit and if you are like me and don't have a lot of tools I would recommend buying the tool kit. One last recommendation,...

One last recommendation, I would use the video provided by Keiser on YouTube to help guide you through the assembly process and I highly recommend that you watch the whole video all the way through before you even receive the Keiser M3i Indoor bike.
