Difference between Keiser M3 plus and Keiser M3i

The Keiser M series spin bikes are all the same and different in so many ways. For instance, the M3i is much better than its first edition the Keiser M3 plus indoor bike in so many ways from the design to the tech devices found in it. Some of the differences are visible and easy to see while others are a bit technical and require expert analysis.

The M3+ spin bike is as good as any indoor spin bike but it is no “I” series as it lacks Bluetooth connectivity and a free app for easy transfer of data from its computer. Besides, you can track and analyze your workout sessions with the improved version.

The M3 only allows you to see how you perform while working out but it does not record or upload any data for future analysis.

Moreover, the Keiser M3 plus handlebars do not move horizontally, this can be a problem to most people because as you increase its height it moves away from you and as you lower it they get closer to you. This can highly reduce your chances of maximizing its benefits as you cannot work-out some routines without the handlebars.

Likewise, it can be uncomfortable as not everybody has the same torso or leg measurement even if they are the same height. You can end up with a handlebar too close for comfort or far away from reach.

But the M3i Keiser spin bike is far better and advanced when it comes to handlebars. Its handlebars often move horizontally to accommodate the 45-degree angle of the vertical adjustment. This enables you to set the bike into a comfortable position without feeling crammed in a small space or stretched far away from its handlebars.

Besides, the handlebars of the M3i can also move upwards, downwards, backward and forwards so as to maximize your workout sessions.

The “i” series also has pre-set holes on its adjustment pole for safety and precaution. This is to allow the seat to slip to the nearest hole in case the adjustment knob has not been fully tightened. But you do not have to use them when adjusting the height of the seat as you can tighten it in place, into a height you want.

Moreover, they both have an LCD display unit for keeping track of distance, time as well as pulse and power output. The only difference is that the newer version has Bluetooth and wireless connectivity that makes it easy for group instructors to hook it to a receiver and project it on a big screen for the class to see.

The “i” series also has a convenient media tray for phones and tablets. You can listen to music as you work-out or watch movies and TV shows as you exercise.

They both have well-designed rear wheels that protect the whole spin bike from corrosion as well as sweat. You can exercise as long as you want and never worry about water or sweat spoiling the wheels or messing with your session.

Conclusively, they are both durable as well as highly functional and can last over a decade if well-maintained. They are also quiet, comfortable and easy to use. And both come with a free exercise mat.

Besides, they do not come cheap as the newer version is more expensive when compared to the Keiser M3 plus indoor cycle. But this is largely due to its upgraded tech devices as well as convenient and easy to use handlebars as well as other features.


Basically, if you want to track you workout session then the Keiser M3i is all you need. This Keiser spin bike can be used by anybody due to its V-shaped design as well as adjustable handlebars angles.

Moreover, it is easy to move, use as well as maintain and can fit in your home nicely. So, invest wisely when it comes to indoor cycles and go for this upgraded spin bike and you will never bother with actual road bikes or pay gym fees.

Besides, it can accommodate a maximum weight of 300lbs. You just adjust it accordingly and you will be fine, no stress no hustle.
