THE BIKE THAT KEEPS RAISING THE BAR
M3i INDOOR BIKE
Model 5506
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.
