The Keiser M3i Indoor Bike is a precision-engineered indoor cycle designed, built, and assembled in the USA. Its magnetic resistance system delivers a whisper-quiet, frictionless ride with smooth, reliable performance that has made it a staple in elite cycling studios and high-performance training facilities worldwide.

The V-shaped frame accommodates riders from 4'10" to 7', mimicking the feel and geometry of a road bike. Bluetooth connectivity pairs with the Keiser M Series app, Zwift, Peloton, and other popular platforms for real-time tracking of power, cadence, distance, and heart rate. Dual-sided pedals with SPD clips and toe cages allow any rider to get on and go.

With a commercial-grade Poly-V belt drive, corrosion-resistant finish, and a backlit M Series console, the M3i is built for studios, gyms, and home users who demand precision, durability, and total silence from their indoor bike.
