I’ve been researching spin bikes for almost 3 months until I read a review on the Keiser M3i. It’s the highest rated spin bike for quite a long time now! Now I know why! It’s so silky smooth and so quiet my wife couldn’t even tell I was spinning until she saw my legs moving. Fitness Zone has the best price, great customer support, Kyle is very knowledgeable and friendly and he answered all my questions and concerns. Free shipping and it only took 2 days! The Keiser M3i bike was shipped double boxed and everything was so secure dust couldn’t even move in there! 😁 Needless to say, this bike is fantastic. Make sure you buy it from Fitness Zone you will not be disappointed!

This is my first stationary bike ever, and it is so quiet I can ride it any time of day without disturbing my partner who works from home. Also, it's such a smooth ride that I thoroughly enjoy spending time on it. I have it paired with Zwift, and I highly recommend it! Thank You FitnessZone for your fast service! Buy the Keiser M3i!

Keiser has been the first to employ magnetic resistance, introduce power, and now the first to receive accuracy certification. Keiser is the undisputed number one leader of Indoor cycles.

M3i Indoor Cycle - Keiser introduces intelligent cycling and the most technologically advanced indoor group cycle ever, the Keiser M3i featuring Bluetooth wireless display. The new Keiser Bluetooth wireless computer is certain to become popular with both riders and group exercise instructors. The computer can transmit to a receiver for projection onto a screen and can also partner up with a wireless phone or tablet. At first glance the Keiser M3i Cycle catches the eye with a stunning new black color scheme that also features a red flywheel guard. The M3i is a highly innovative indoor cycle and is one of the most recommended indoor bikes on the market, and for good reason. With its exceptional, club-quality features, this particular product has been designed to last for life. Best of all, this machine delivers exactly what it promises and several users have claimed to have lost a staggering amount of weight after using this bike for just a few months. More importantly, though, this item is surprisingly easy to use, even for beginners. 

The new Keiser M3i gives consistency and accuracy that will give both Instructors and riders the confidence they need to really use power as a training tool in classes, but the indoor cycling pros at Keiser are raising the bar. Keiser announced in March that they achieved the prestigious EN-ISO 20957-1 rating for the accuracy of its power display on the newly released Keiser M3i indoor cycle. The new certification means that Keiser M3i's are the most accurate in the market when it comes to measuring the power (in watts) output by riders.

The Keiser M3i can now connect to your phone and sync the data from your workout, which acts as a more accurate way to measure your progress between multiple workouts.

If you're already familiar with the earlier Keiser M3 model, you'll notice that the new Keiser M3i has an added area of adjustment.

    Keiser M3i Indoor Cycle EDDY CURRENT SYSTEM

    An eddy current is an electric current in a conducting material that results from induction by a moving or varying magnetic field. On M Series equipment this is generated by two opposing magnets passing over the flywheel. The flywheel (a conductor) passes through the magnetic field generated by the two powerful magnets. By varying how much of the flywheel comes into contact with the magnetic field you can increase or decrease the amount of resistance for the rider. As no parts in the resistance system ever touch there is no wear on the system.

    When the flywheel is turned in proximity of the magnetic field the eddy current is created. The flywheel acts like a conductor with closed circuits. The energy generated by turning the flywheel has nowhere to go, so as it resists it becomes more difficult for the rider to pedal. If the flywheel is in less contact with the magnetic field it's easier to ride. The more of the flywheel that comes in contact with the magnetic field (the higher the energy that is being generated with each turn) the more difficult it becomes to ride. The Keiser M3i is a quaity magnetic indoor cycle!

    Fig. 1. At full resistance the flywheel is in most contact with the magnetic field. When you reduce the amount of contact to the field (move the magnets away) the resistance then decreases.


    The unique M Series
    cardio line features Keiser's innovative magnetic resistance system. Designed, engineered and manufactured in the U.S. to strict quality standards and test procedures, which guarantees an extremely durable and effective machine. You can also outfit Keiser M Series equipment with our intuitive M Series computer. Motivate and empower by accurately tracking and measuring: Workload (watts), Heart Rate (Polar compatible), Time, Distance and Cadence.

    Like most of you i did plenty of research before i decided on this bike. It was more than i was anticipating spending but after getting it, it's very clear that this bike is very well made and will last a long time. It feels rock solid and buttery smooth. With multiple ways to measure fitness and progress I look forward to seeing where it takes me. If your on the fence go ahead and do it, i feel confident this bike will not disappoint you.

    This has to be one of the best indoor cycles on the market! I have been going to spinning classes for a few years and love this bike. FitnessZone gave me a great price and shipping it out fast. It took me about 45 mins it to assemble. I watched a youtube video on how to put it together. I researched several companies that sell it and even considered Amazon, but I wanted to buy from a company that has a service dept. if I ever needed parts or tech support. Amazon doe not offer this service! I also researched a few sites that offer a lifetime parts warranty-I realized that it was a scam! I decided to buy from FitnessZone! Their staff took the time on the phone to even go over any questions that I had. I had a little scratch on the plastic cover and Randy Jones their service manager sent me out a new part the next day! I hope this review help you in your decision to buy this awesome product! Thank You Karen
    Extremely pleased with our Keiser M3i bike! Very well made.

    We ordered the Keiser M3i bike a few weeks before the winter holidays in 2017. It is outstanding. The assembly was straightforward and proceeded smoothly. The bike was ready in under 1 hour. The mechanics of the bike are impeccable. We have four riders who range from 12 to nearly 50 years of age and height from 4'11" to 5'8" and all fit comfortably. Adjusting the bike is easy and it has a very solid feel. Pedaling is extremely smooth and the resistant adjustment both very precise and easy. I have sync'ed the onboard computer with the Keiser IPhone app and it does a great job recording job recording the details of my workouts. I've used it to progressively increase average power as I exercise. The bike has been used each day and we've had a great time with it.

    The Keiser M3I is a wonderful indoor cycle. Tried the Schwinn which is a nice ride also , but the Keiser was a much smoother and comfortable ride for us. For those folks who may have questions about the Bluetooth/GoInd app, the new release works great, non of the connectivity problems of the old release. We are running it on a IPad Air 2. The app is actually a good training tool. Now to the meat of the matter. The staff of the Fitness Zone are just wonderful to work with. Per Fed X we lived too far in the woods for their standard semi delivery. The Fitness Zone arranged for for pickup from the Fed Ex Depot and assembly in the basement of our home, that was flawless (yes, it was a few extra bucks , but worth every penny) Bottom line 6 days after ordering the M3I it was in our home, assembled and we were riding on it.
    Great bike, great purchase process!

    I love this bike! I've been riding the Keiser M3 bike in my local gym's spin classes for a few years now, and have been really impressed with them. These Keiser M3 bikes are very high quality and have great finish/design. The bikes at the gym have held up very well to a high use/abuse environment, and the magnetic resistance system seems far more consistent and reliable than the friction based bikes they replaced. Based on this experience, I'd initially been looking at the Keiser M3 for home use. However, the newer M3i bike looked like an improvement over the M3 for my needs (its bluetooth computer able to log its data to an M3i compatible fitness app (GoInd) on my iPhone. Ordering the M3i at the fitnesszone website was straightforward. I opted to take advantage of the $50 discount (for not taking one of the free gifts), as well as the free BT heart rate Strap, gel seat cover, and mat. The free shipping was an incentive too. The order shipped out from Fitness Zone very quickly via FedEx freight, despite being ordered between Christmas and the new year. There are a number of useful Youtube videos online, which were helpful for preparation ahead of delivery (to identify the tools required, and become familiar with the assembly process). FedEx delivered the order, calling to schedule delivery. The Bike was shipped on a wooden pallet, shrink wrapped with a box containing the ordered accessories. The M3i itself comes double boxed from Keiser for additional protection during shipping, and the cardboard is heavy duty. I was able to move the M3i box inside myself without issue, but you may want to have a friend on-hand if you're concerned about doing so (it weighs a little over 100lbs I believe). Assembly was straightforward using the included assembly instructions, having watched a couple of Youtube M3 assembly videos. I'd say it was a little less than an hour overall. Required tools are listed as: - Torque wrench (Minimum 45 Nm / 35 ft-lb) - 4 inch extension - 15mm open-end wrench - 16mm, or 5/8 inch open-end wrench - #2 Phillips screwdriver - 15mm crowfoot - 16mm, or 5/8 inch crowfoot - 5mm Allen Wrench - 6mm Allen Wrench - Paste or spray wax (used to clean after assembly) - Clean cloth - LPS #3 (corrosion inhibitor) I've used the bike a few times to-date, and the Bluetooth integration with the iPhone and GoInd app works very well. The GoInd app records the data displayed on the M3i Bike computer over the duration of the workout, so you can track power/HR/cadence output over time. The GoInd app also offers a couple of "in-app purchases" to enable additional features, such as the ability to save workouts, and a fitness test, which were useful to me. If you do use this app, remember to set the app option that stops screen lock when the app is running... this keeps the device/app from going to sleep, so that it's always visible. Battery drain does not seem to be an issue in my experience (low power BT, so screen illumination likely the biggest draw). So, to summarize, I'm extremely happy with the Fitness Zone purchase experience, and the M3i!
