Keiser

Keiseris the American company that revolutionized the fitness industry with pneumatic resistance instead of the classic weight stack.

The Keiser M3i Bike revolutionized the world of Indoor Cycling thanks to a series of technical features that make it unique. Keiser M3i was the first bike on the market to adopt magnetic rather than mechanical resistance, as well as a belt drive.

This choice has made pedaling extremely smooth and constant, very similar to that of a road bike.
