WE BUILT THE ULTIMATE INDOOR BIKE More than 20 years ago, Keiser set out to create a bike that would exceed the demands of indoor group cycling.

V-SHAPE FRAME MATCHES RIDERS OF ALL SIZES Many indoor group cycling bike manufacturers talk about providing a road-bike experience, but they failed to recognize what’s important about road bikes: FRAMES VARY TO ACCOMMODATE RIDERS OF DIFFERENT SIZES. Our solution was to engineer the industry’s FIRST V-shape frame for an indoor bike. Our V-shape frame design allows the M3i to mimic different road-bike frames by allowing the seat and handlebars to be simply raised in conjunction with one another to adjust for longer legs, torsos and arms. The M3i matches riders from 4’10” to 7’ (1,473mm to...

REAR-WHEEL DESIGN Further protection of drive-train The angled channel on the bike frame flows excess fluid away from the drive-train. Other indoor group cycling bikes mistakenly place the rider’s sweat zone directly over the flywheel and other vulnerable mechanisms — an obvious engineering flaw that leads to corrosion, excessive cleaning and a shorter bike life. Keiser was the FIRST to put the flywheel at the rear of a bike, allowing the M3i to be more reliable, easier to clean and better protected from sweat and corrosion. Less maintenance, longer bike life With superior sweat protection,...

MAGNETIC RESISTANCE TRUE POWER READINGS It’s easy to “claim” accuracy, but we guarantee it. As the FIRST company to use magnetic resistance, Keiser revolutionized indoor cycling by delivering a quiet, reliable ride with immediate accurate data for EVERY M3i bike. And unlike most competitors’ bikes, the M3i has been certified for accuracy. The M3i is the FIRST indoor bike to receive the globally recognized EN957-10 certification for accuracy and safety. IMMEDIATE RIDE DATA The FIRST indoor bike designed to predict the power generated at any speed in any gear — ensuring that both instructors...

THE FIRST DRIVE-TRAIN SPECIFICALLY DESIGNED FOR MAGNETIC RESISTANCE The competition endorsed Keiser's engineering by following our lead on using magnetic resistance - but they should have also copied our drive-train design. Our simple drive-train, with just a single Poly-V belt, produces the higher speeds necessary for a lighter-weight aluminum flywheel to provide the kinetic energy and magnetic resistance to simulate a good road-bike experience. Using an outdated drive-train, designed for heavier flywheels, our competitors must use a perimeter-weighted flywheel to accomplish the same...

CURVED CRANK ARMS TO FIT WIDER HIPS AND BULKY SHOES Instead of using straight crank arms to achieve a narrow Q Factor, Keiser recognized the need for versatility. We added curvature to the M3i crank arms to maintain the proper distance for wider hips and any type of rider footwear, from narrow bike shoes to the bulkier gym shoes most commonly worn in group classes. Many indoor group cycling bike manufacturers talk about the distance between their bike’s two pedals, and boast about their narrow Q Factor. But their bikes were built around the narrow shoes and pelvises of elite cyclists, even...
