Keiser M3i

Keiser M3i

The M3i is the result of more than a decade of refining the M3 and of hundreds of changes - from managing the path of sweat around the bike and better corrosion resistance to a power meter so accurate that the M3i was the first indoor cycling bike to pass the European EN957-10 standard for accuracy and safety.

It did not stop there: one sample passing the test is not enough, so Keiser introduced a quality control and testing programme that ensures every bike produced passes it.

Keiser Dynamic Variable Resistance

Keiser's Dynamic Variable Resistance is designed to provide a smooth, consistent force curve at any training speed. Each machine has its own resistance curve, tuned for the muscles used in that particular exercise. For the user it means training at maximum efficiency at whatever speed they work.
