Keiser M3i Studio Indoor Bike

$3,885.00

The legendary M3i with an innovative new display

The new studio display: Advanced features to bring your ride data to life: Ride By Color™, 72 Gears, Latest wireless fitness technology, No cord, no batteries.

The first M3 Indoor Bike was introduced in 2006 and featured Magnetic Resistance, a Simple Self-Tensioning Poly-V® Belt Drive, and a Display that showed the Power you were producing in Watts—all firsts in Indoor Cycling. It raised the bar so high, it took four years for our competition to respond. The M3 of today is also the beneficiary of over a decade of refinements, including the same power accuracy as the M3i. It features a four-way adjustable seat and a two-way adjustable handlebars.

V-SHAPED FRAME

MATCHES RIDERS FROM 5′ TO 6’2″

(1524 mm to 1880 mm) tall with a weight capacity of 350 pounds (159 kg).

ROAD-BIKE FRAMES VARY 
TO FIT RIDERS OF DIFFERENT SIZES.
Img-M3-Road-Bike-Frames-NEW
Keiser’s v-shaped frame mimics the sizing of different road-bike frames.

The M3i Indoor Bike’s seat and handlebars adjust for legs, torsos, and arms of different sizes.

REAR-FLYWHEEL DESIGN

MORE RELIABLE. BETTER PROTECTED.

Sweat can lead to corrosion, additional maintenance, and shorter bike life.

KEISER MOVED VULNERABLE MECHANISMS OUT OF THE “SWEAT ZONE”

By moving the flywheel to the rear, Keiser moved the bike’s drivetrain and other vulnerable parts out of the rider’s “sweat zone.”

  • Reduces the need for more maintenance.
  • Protects against corrosion.
  • Extends the life of the bike.

POLY-V BELT DRIVETRAIN

A QUIET, SMOOTH, ROAD-BIKE EXPERIENCE — AND NO MAINTENANCE.

DESIGNED FOR MAGNETIC RESISTANCE.

We designed the industry’s first indoor bike with magnetic resistance. And we designed a drivetrain to go with it.

The key to the M3 Series drivetrain is its single Poly-V belt. It transmits high loads over very small pulleys. This enables M3 Series bikes to achieve a good road-bike experience with a lightweight, aluminum flywheel.

The Poly-V belt is perfect for transmitting high loads over very small pulleys.

POLY-V BELT

THE CHOICE OF AUTOMOTIVE MANUFACTURERS

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

No required maintenance, zero adjustments
  • Pre-tension design requires zero adjustment.
  • Drive-train requires no maintenance other than routine inspection.
Avoids the problems of many indoor bike designs
  • No heavy, perimeter-weighted flywheel.
  • No complex, multi-belt drivetrain.
  • No unnecessary noise and vibration of a cog belt.
CURVED CRANK ARMS TO FIT EVERY RIDER

We curved the crank arms on our indoor bikes to fit a wider variety of riders and their workout shoes.

M SERIES PEDAL

  • Forged chromoly steel axle heat-treated for maximum strength.
  • Standard workout shoes or cycling shoes with SPD cleats.

EASY TO TRANSPORT

With fewer parts, a lighter flywheel, and precise weight distribution, M3 Series bikes are very ease to move. And their small footprint makes them easy to place and store.
