Last Updated on January 3, 2023 by Jeff

Keiser M3iLet’s get started:

The Keiser M3i is a groundbreaking new entry into the indoor cycling and Spinning bikes market. The M3i is the first to feature a Bluetooth wireless computer. For group exercise classes, data from the M3i computer can be projected onto a display. With an app, riders can download their data from the computer to a smart phone or tablet.

Also innovative in terms of accuracy testing of its power display, the Keiser M3i is the first indoor bike to pass EN ISO 20957-1 certification by TUV Product Services, a European safety organization. With this certification you can be sure that you are receiving accurate feedback on your workout within + 10%.

Like it’s popular teammate, the Keiser M3 Plus, the Keiser M3i is more than its eye-catching sleek design and cutting edge technology. The seat and handlebars are adjusted quickly with a unique pull-pin system unlike other cycles. The four-grip position handlebars are great from utilizing different riding positions.

Shipping and Assembly:

Shipping costs will vary for the M3i depending on where you purchase from and what type of delivery you prefer. However, some retailers, such as, will provide free shipping (check Amazon here).

Keiser provides a very illustrated and easy to follow manual for this process. With that being said, you will need to do a little more assemble with the M3i than most other cycles. For instance, you’ll need to attach the flywheel, adjustment poles, stabilizer bars, handlebars, saddle, pedals and console. Plus, you have to do it all with your own tools, because they aren’t supplied. In all the assembly process is easy and should take you about an hour to complete.

Keiser M3iWhat We Love About the Keiser M3i:

Design & Functionality

There are some great looking indoor cycles on the market and the Keiser M3i is at the top of that list. The rear mounted flywheel, aerodynamic design and eye-popping color scheme are sure to please just about everyone. But the M3i isn’t just all about looks. The seat and handlebars are completely customizable to the rider by simply pulling a pin and making the adjustment. The handlebars themselves provide the user with four different grip positions to accommodate riding styles. But the eddy current magnetic resistance system leads the M3i’s functionality by ensuring smooth transition between “gears.”

Bluetooth App ConnectivityKeiser M3i Review

While there are a lot of older reviews saying that the one drawback of the M3i indoor cycle is that you can’t connect to any apps, it appears this issue has been resolved. The Keiser M3i now seems to be able to function with the GoInd App, an app specifically designed for indoor cycling. This app collects and stores workout data so that you can track your performance over time. It also uniquely overlays multiple graphs of your data such as heart rate, RPM and power output.

Other Considerations:

While the computer does display workout data and allows you to download it through apps, it does not provide any preprogrammed workouts. It’s not a deal breaker, and most people don’t mind as they’re happy creating their own or watching a video online.  Programmed workouts are great motivators to get you on the cycle and to help you push yourself for a more intense workout. If this is something that you are looking for, there are plenty cycles in this price range that provide programmed workouts.  On the other hand a lot of people don’t need programmed workouts and just do their home workout while listening to music or watching TV.  You can even find full Spin workouts on Youtube like the one at the end of this review.

Final Word on the Keiser M3i Indoor Cycle:

The design and appeal of the Keiser M3i is worth $2,000 alone. The functionality and Bluetooth technology that allows the user to download and track workout data takes it over the top.  Overall, if it’s in your budget, the Keiser M3i is a high end machine that can take your fitness to the next level.  And again, as a bonus for the holiday shopping season, it looks like you’ll get a quality exercise pad to put the cycle on.
