I absolutely love my M3i Spin Bike

VERIFIED PURCHASE
I purchased the M3i Spin Bike because our health club has been shut down since March 17th and I still have no idea when our state will allow it to reopen, so no spin class for me until, well, who knows. It got to the point where I couldn’t wait any longer so I treated myself to my own spin bike. We have these same ones in the spin studio, so I am very familiar with it. Being a brand new, never been used before bike, I can really appreciate how well it is made. Took the two of us about an hour and a half to assemble from the time we unboxed it. The instructional video was extremely helpful for this. It comes with a Polar heart rate monitor with chest strap. I use the media tray for my iPad, on which I have the Keizer app to track...

I use the media tray for my iPad, on which I have the Keizer app to track each of my sessions. This spin bike is easy to use. Enough up & down and forward & aft adjustments for the seat and handle bars to fit any height person. I am 5’1” and have no issue. The base has a small footprint so it fits nicely in the corner of the room with plenty of space to ride. Very happy.

Superb performance that is smooth and quiet

I purchased this bike to use with the Peloton digital app and it works perfectly. Using the Peloton app I can see my heart rate and am able to stream workouts via AppleTV. It fits perfect for my small size at 5.3", and soon my 9-year will fit the bike too! It is so quiet, the kids don't even mind if I ride while they watch a movie in the same room!

Best bike on the market, IMHO

VERIFIED PURCHASE
I work in the fitness industry and part of my job includes equipment research, recommendations, purchases and maintenance for 7 facilities. Over 8 years ago I ordered Keiser bikes to replace the maintenance nightmare bikes we had in our facilities. Up to now, only 2 minor parts (leveling knob, pressure block) have been replaced on these bikes and that design was changed on the M3i (Keiser is obviously paying attention). From that experience, and after looking at nearly everything on the market, this is why I bought the M3i for myself: (Light weight) Rear Flywheel (sweat is very damaging and I sweat excessively), belt drive (no chain to fix), magnetic resistance(no brake pad to replace/belt to adjust), 4-way seat/handle bar adjustment, dual-sided pedal, sweat protection on frame. After riding the M3i, I'm more in love! It's so smooth, the media tray and new pedal design are fantastic and I can't...

The only disappointment was finding out I missed the promotion and the floor mat doesn't come with it, when I have to put it on carpet. This has absolutely nothing to do with the quality or performance of this bike and, IMHO, this is the best bike on the market.

Best indoor spinning bike for us.

Beautiful high end bike, smooth rotation, tight well built. We love it. Perfect for people who when walking and running(haha) anyway can’t get heart rate up. Indoors on this...oh yea we can and no worries on crazy out door hazards.❤️ It.

Being Good Enough, Just isn't.

The more I learned about Keiser the more I realized that there is no substitute for quality and commitment. Setup was easy. Instructions clear. Simple start up.

Five Stars - M3I

VERIFIED PURCHASE
Really nice piece of equipment. My club shut down due to the virus so I wanted to continue spinning. After doing loads of research I settled on the Keiser. If you're serious about spinning and want a heavy duty "magnetic" bike, you can't go wrong with this bike. The bike isn't cheap but is priced in-line with other widely advertised machines. I don't need the added monthly subscription (virtual spin classes) expense that goes with the some of the equipment providers. I just wanted a good solid well built machine. I am 2 months into ownership now and not a single issue with my wife and I both spinning a minimum of 4 days/week. I'm 6'2" and about 210 and this bike doesn't move when I'm climbing up the mountain. Don't settle for something cheap and lightweight,(lots of cheap Chinese...

Don't settle for something cheap and lightweight,(lots of cheap Chinese stuff out there) you will be very disappointed. My club is now open but I will continue to spin on my own bike at my own time to my personalized play list. The only minor suggestion to Keiser would be to provide a drink holder. The complimentary heart rate monitor is still in the box but a drink holder would have been nice instead or in addition.

Keiser responded:

B. Dubya,

It's not the best known feature of our cycles but there is a water bottle holder built into the frame cover of our bikes. There's a concave section of plastic with a flat area for your water bottle. Water bottles that are thinner work best.

Thank you,

Great bike!

VERIFIED PURCHASE
I ordered this spin bike after our gym had been closed for several months. We are completely satisfied with everything about it. I brought it to our bike shop and they put it together perfectly. Highly recommend!
