INNOVATION, UNCHAINED.

Introducing Carbon Blue™ technology – a belt drive system combining unmatched durability with the authentic outdoor biking feel you expect from Schwinn. For nearly 20 years, Schwinn carbon blue belt drive bikes have led the indoor cycling industry. Even as other companies began to use belt drives, we stayed true to our technology for one simple reason: belt drives felt nothing like riding an outdoor bike. Today, all of that is changing. There is a revolutionary new belt drive taking the outdoor bike community by storm, and we’ve adapted it and brought it indoors on the A.C. Performance. This next generation system delivers guaranteed durability and virtually zero maintenance, without sacrificing the Schwinn authentic cycling feel that riders know and love.

CARBON BLUE™

Several years ago, a company named Gates introduced a concept never before seen on outdoor bikes – a belt drive that performed like a chain. Their innovative system – called Carbon Drive™– features a carbon fiber reinforced belt with teeth for maximum durability and true bike performance. Over time, this has transitioned from a novelty system to a mainstream solution used on hundreds of outdoor bike models today. Over the past year, we have worked with Gates to adapt this revolutionary technology to our A.C. Performance bike. The result is a new belt-based drive system that combines the maintenance-free durability and performance of a belt with the authentic-ride feel of a chain. We call it Carbon Blue ™ – those who ride it call it “incredible.”

Thanks to the lessons learned from our past generations of bikes and our constant innovations, the Keiser M3i isn’t just any indoor group cycling bike.

It’s the industry’s only indoor group cycling bike built around YOU. That’s...

YOU the rider

YOU the gym owner

YOU the service technician

HERE’S HOW WE DID IT.

---

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’ (1473 mm to 2233 mm) tall with a weight capacity of 350 pounds (159 kg).

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.

Further protection of drive-train

The angled channel on the bike frame flows excess fluid away from the drive-train.

Less maintenance, longer bike life

With superior sweat protection, gym owners can save money through lower maintenance costs and a longer bike life.

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 nerve center of the M3i

The simple, elegant axle assembly is the core piece responsible for predicting and delivering accurate ride data, EVERY TIME — and EVERY COMPONENT is inspected to meet precise tolerances.

TRUE POWER READINGS

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 and riders are provided with accurate ride data immediately.

GUARANTEED CONSISTENCY

Our relentless Quality Control procedures ensure that every M3i delivers the same immediate accurate ride data, bike after bike after bike. And every day an M3i production bike is randomly dyno-tested to ensure quality and accuracy

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 thing.

They even brag about their perimeter-weighted flywheel, cog-belt drives or crank-arm-to-flywheel ratios. But what they’re really telling you is...

THEY DESIGNED

THEIR BIKE WRONG.

No required maintenance, zero adjustments

The belt’s pre-tension design also requires zero adjustments, and the M3i drive-train requires no maintenance other than routine inspection.

The Poly-V belt is THE choice of automotive manufacturers

The Poly-V belt is the preferred choice to run the accessories on the front of car engines, because it’s so quiet, durable and reliable.

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 though footwear of any width and people of all body shapes can be found in group cycling classes.

WHY WOULDN’T YOU DESIGN A BIKE TO FIT

EVERYONE?

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.

THE REVOLUTIONARY

KEISER M SERIES PEDAL

Keiser also set a new industry standard with our SPDcompatible M Series indoor group cycling bike pedal. Engineered beyond consumer standards for group classes, it’s more than a pedal — it’s a game changer, providing superior comfort, safety and durability.

The M3i features a wide array of details, benefits and features, offering additional fit and comfort for riders, enhanced durability for gym owners, and simplified upkeep for maintenance technicians.

Simplified maintenance

M3i drive-train can be accessed by removing just eight Phillips head screws vs. over three times more on some competitors’ bikes.

Standard media tray

For holding cell phones and tablets

Easy access to shifter

Mounted directly to handlebars for ease of use and increased safety, especially when riding out of the saddle. Interval training is activated by simply pushing the shifter all the way down and back up, making it ideal for HIIT workouts.

Water bottle holder

Incorporated into frame design and fits both small and large sizes

Easy-to-adjust seat and handlebars

Quick, intuitive vertical and horizontal adjustments of seat and handlebars.

Robust knobs

Requiring less maintenance than a traditional cam-lock.

Wide array of hand positions

Continuous design of handlebars provides multiple hand positions for indoor cycling.

Stretch pad

Located on bike base to facilitate pre- and post-ride stretching.

Easy to transport

Fewer parts and a lighter flywheel for ease of transport.

THE M3i FITS RIDERS

FROM 4'10" TO 7' UP TO 350 POUNDS

The v-shaped frame allows the seat and handlebars to be adjusted for adult riders of almost any size. Horizontal adjustments provide further ability to get a perfect fit for any rider

"MY SON IS 6'10’ AND A COLLEGE ATHLETE SO WE NEEDED A DURABLE BIKE THAT WOULD ADJUST TO FIT HIS HEIGHT. THIS BIKE WAS PERFECT. I LOVE THAT WE CAN EASILY ADJUST BOTH THE SEAT AND HANDLE BARS TO GIVE EVERYONE IN OUR FAMILY A PERFECT FIT. "
Nancy Kreiner | Okoboji, IA

THE M SERIES PEDAL

WORKOUT SHOES OR SPD CLEATS

Use your favorite standard workout shoes with the built-in toe clip straps on the M3i. Or, flip the pedal over to use your favorite cycling shoes with popular SPD cleats. To use another cleat style, simply replace the pedals with your choice of standard bike pedals (9/16" x 20 TPI) that accept your desired cleat.

M3i Indoor Cycle - Keiser introduces intelligent cycling and the most technologically advanced indoor group cycle ever, the Keiser M3i featuring Bluetooth wireless display. The new Keiser Bluetooth wireless computer is certain to become popular with both riders and group exercise instructors.

The computer can transmit to a receiver for projection onto a screen and can also partner up with a wireless phone or tablet. At first glance the Keiser M3i catches the eye with a sexy new black color scheme that also features a red flywheel guard.
