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.

DESIGNED AROUND YOU

The Keiser M3i is the industry’s only indoor group cycling bike built entirely around YOU – that’s YOU the rider, YOU the gym owner and YOU the service technician. Game-changing features on the M3i include:

• V-shape frame to accommodate all riders
• Rear-wheel design for protection from sweat and corrosion
• Magnetic-resistance technology for greater repeatability and reduced wear
• Quiet, reliable and low-maintenance single-belt drive train
• Revolutionary re-designed Keiser Bike Pedal
• Bluetooth® wireless signal for open API for tablets and smartphones

ALL THE DATA YOU NEED ON A SINGLE SCREEN

We designed the M3/M3i Indoor Bike computer to be simple, with everything a rider needs to know on a single screen. This includes RPM (Revolutions Per Minute), Power and Energy (Watts and Kilcalories), Heart Rate, Elapsed Time, Gear and Trip Distance. Additionally, the back-lit display turns on when the room light drops below a set level and – unlike other indoor bikes – remains on.

KEISER M SERIES BIKE PEDAL

With our game-changing bike pedal, Keiser has again revolutionized indoor cycling down to the last detail. New pedal features include:

• Stronger bearings tested for static and dynamic loads
• Cage integrated into pedal design, not just added on
• Ramped barbs for secure and simple foot placement
• Curvature eliminating pressure points on the rider’s foot

"VERY EASY TO ASSEMBLE"
Leila | Hollywood, FL

"I AM MOST CERTAINLY NOT HANDY, BUT IN NO TIME I WAS RIDING ON THE BIKE"
Steve | Raymond, ME

"LOVE LOVE LOVE! THE M3I WAS SO EASY TO PUT TOGETHER. THANK YOU."

Sustainability: Creating positive impact through thoughtful action. In order to reduce our packaging’s negative influence on marine life and waterways, we have replaced expanded polystyrene (EPS) with 100% recycled corrugate, which can be recycled again to also use less raw material. Look for ways to reduce your disposal fees and environmental impact with recycling!

In order to reduce the global demand for batteries, we have replaced our consoles requiring periodic changing of batteries with group cycles that generate power from pedaling. When not disposed of properly, batteries release harmful metals such as mercury, lead and cadmium into the environment. Look for ways to reduce your environmental impact with generator-powered electronics!

TECHNOLOGY

Zone Console: Paired with 4iiii’s industry leading 3-dimensional strain gauge powermeter, the Zone Console displays the most accurate power, direct from the member. It is the most reliable and authentic indicator for performance in cycling. The Zone Console allows members to use FTP input, making zones personal.

Instructors will love uniting a class with color, allowing members at both ends of the fitness spectrum to ride side by side with the same intensity and sense of accomplishment. Schwinn’s broad-based approach reduces the traditional number of Power and Heart Rate training zones to 4 to align with ratings of perceived exertion, creating more accessible and attainable programming for instructors and members alike. Zone-colored LED lights next to the flywheel display each member’s intensity, encouraging the class to Ride As One.

OpenHub Console Connectivity: Our goal is to provide the best technology solutions possible for our customers and their members. Partnering with 4iiii, we created the Zone Console to be an open platform with connectivity options like Bluetooth, NFC and ANT+.

TECHNOLOGY

Zone Console: Paired with 4iiii’s industry leading 3-dimensional strain gauge powermeter, the Zone Console displays the most accurate power, direct from the member. It is the most reliable and authentic indicator for performance in cycling. The Zone Console allows members to use FTP input, making zones personal.

Instructors will love uniting a class with color, allowing members at both ends of the fitness spectrum to ride side by side with the same intensity and sense of accomplishment. Schwinn’s broad-based approach reduces the traditional number of Power and Heart Rate training zones to 4 to align with ratings of perceived exertion, creating more accessible and attainable programming for instructors and members alike. Zone-colored LED lights next to the flywheel display each member’s intensity, encouraging the class to Ride As One.

OpenHub Console Connectivity: Our goal is to provide the best technology solutions possible for our customers and their members. Partnering with 4iiii, we created the Zone Console to be an open platform with connectivity options like Bluetooth, NFC and ANT+. This feature allows owners and members to select and work with the Fitness Technology and Apps that meet their needs.
