Keiser M3 Exercise Bike with Computer

The Keiser M3 Indoor Cycle sets the standard for professional spin training — a result of over a decade of innovation and engineering excellence. Built from corrosion-resistant materials with a maintenance-free magnetic resistance system, the M3 delivers whisper-quiet operation and lasting performance trusted by elite studios and home athletes alike.

Every detail is designed for seamless functionality: four-way adjustable seating, dual-position handlebars, Shimano™ combo pedals, and an intuitive resistance shifter that allows infinite tension control. The optional onboard computer displays real-time RPM, power (watts), calories, heart rate, gear, and distance, giving riders full visibility into their effort and progress.
