Assembly made easy
Your M3i Indoor Bike is designed to be easy to assemble. And it ships with easy-to-follow instructions. Watch our online assembly guide video to see how easy it truly is.
THE BIKE THAT KEEPS RAISING THE BAR
The M3i is the culmination of over a decade of refinement of the M3 and hundreds of changes, from mastering the flow of sweat around the bike and better corrosion resistance, to a power meter so accurate that it was the first indoor cycling bike to pass the EN957-10 European Standard for accuracy and safety. But we didn’t stop there. It wasn’t good enough to have just one sample bike pass the test, we implemented a quality control and testing program to ensure that every bike we produce will pass the test. The M3i continues to raise the bar with the introduction of Keiser Integrated Technology and its ability to transmit to multiple Bluetooth® devices at once; transmitting your workout data to your cell phone or tablet at the same time it is sending the information to the class projection system and any other Bluetooth® device you want.

Frequently Asked Question
What is the difference between the Keiser M3 and M3i?
- Bluetooth-enabled for device and app compatibility*
- 4-way handlebar adjustment (vertical and horizontal)
- Not connected
- 2-way handlebar adjustment (vertical)
The differences are in the handlebars and computer. The M3 handlebars adjust vertically, where the M3i handlebars adjust vertically, forward and backward as well. This means that the M3 fits riders from 5' to about 6'2", and the M3i can support riders from 4'10" up to 7' tall in some cases.
Both cycles come with a computer, but the M3i computer is Bluetooth enabled which gives you access to both commercial and home use fitness apps. The M3i also ships with a complimentary media tray, useful for resting your phone or tablet on the handlebars while cycling.
Is this the latest model?
Yes! Keiser cycles are built to order, and as such you will always receive the latest model.
Which heart rate monitors are compatible with Keiser M Series bikes?
We recommend Polar brand monitors, specifically the Polar® H1 and T31 WearLink® models.
How does Bluetooth® wireless technology work on the Keiser M3i?
The Bluetooth technology on the M3i allows you to train individually, or in a group setting.
Why are the Keiser M3/M3i bikes designed with a light flywheel?
The short version is that the M3 was designed from the ground up with magnetic resistance in mind, it was the first bike of its kind designed in this way!
Groom + Style explains the reasons behind that engineering decision in their article: "Spin Bike Flywheel Weight – Is a Heavier Flywheel Better on an Exercise Bike?"
