Keiser Indoor Cycle M3

Keiser M3 – The classic indoor bike in pure studio quality
The Keiser M3 (5501BBN) is the proven base version of the legendary Keiser indoor cycle series and stands for maximum robustness and uncompromising durability. Developed for professional studio use, the bike impresses with its low-maintenance magnetic braking system, the quiet belt drive, and the stable V-frame construction.
Unlike the M3i, the M3 deliberately omits a display and focuses entirely on a classic, reliable training experience.
Proven Kaiser technology for maximum reliability
The maintenance-free Poly-V pulley drive combined with the magnetic resistance system ensures a virtually noiseless, smooth riding experience. With 24 resistance levels, training can be precisely controlled – from relaxed endurance rides to intense intervals.
The integrated quick stop function provides additional safety for every unit.
Ergonomics & Comfort without compromise
The stable V-frame construction ensures maximum stability and high load-bearing capacity in daily studio use.
The handlebar is vertically adjustable (2-Way), the seat is both horizontal and vertical (4-Way), allowing the bike to adapt optimally to different body sizes.
The combination pedals (SPD click system + basket), comfort saddle, stretch pads, an integrated bottle holder, and transport wheels provide additional comfort.
