INDOOR CYCLES

Keiser M3i Studio Plus Indoor Bike

THE LEGENDARY M3i WITH AN INNOVATIVE NEW DISPLAY

More than 20 years ago, Keiser set out to create an exercise bike that would exceed the demands of indoor group cycling: An indoor bike that fits riders of all body shapes and sizes; a bike that achieves a quiet — but true — road bike experience inside your gym or home; and the ONLY stationary bike built in the United States to ensure the tightest quality control. And we accomplished it all with the Simplest of Engineering Designs.

Speed
You can always access speed mode to track exercise intensity by speed (MPH or KM/H).

COMPATIBLE WITH A VARIERTY OF HEALTH AND FITNESS APPS

The Studio Display can send your cadence, speed, power, and heart rate data to fitness apps. It syncs with devices using ANT+ and Bluetooth® CSCS, CPS, and FTMS.

COMPATIBLE WITH ALL MAJOR PROJECTION SYSTEMS

The display can send rider data to leading projection systems — including Keiser M Series Group App. But while connected to a projection system, it can also share data with apps on a user’s smartphone or tablet at the same time.

FOR ALL RIDERS

ROAD BIKE FRAMES VARY TO FIT RIDERS OF DIFFERENT SIZES

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.

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.

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.

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.

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.

BUILT TO WITHSTAND DEMANDS OF GROUP CYCLING

Stronger bearings tested for static and dynamic loads experienced when rider gets on, off, and rides the bike.
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 easy to move. And their small footprint makes them easy to place and store.

  • V-shaped frame to accommodate riders of all body shapes and sizes from 4’10” to 7’ tall
  • Magnetic resistance for a smooth and quiet workout
  • Infinite incremental resistance changes
  • Rear-wheel design for protection from sweat and corrosion
  • M Series Pedal designed to meet the needs of group indoor cycling demands
  • Self-tensioning Poly-V® belt drive for low maintenance and reliability
  • Robust adjustment knobs that require less maintenance than cam-locks
  • Four-way adjustable seat
  • Four-way adjustable handlebars
  • Media tray, stretch pads, water bottle holder
  • Transport wheels for ease of transport
