V-SHAPED FRAME

MATCHES RIDERS FROM 4’10” TO 7’

(1473 mm to 2233 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.

Fore and aft seat and handlebar adjustments enable 
a perfect fit.

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.

THE M SERIES PEDAL

See how every detail is engineered to exceed industry standards. The result is not just a more user-friendly pedal. It’s also a more durable commercial-grade pedal.

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.
