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. Then, we added it to our elliptical.
The key to the M5 Series drivetrain is its single Poly-V belt. It transmits high loads over very small pulleys. This enables M5 Series ellipticals to achieve a smooth and quiet experience.
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.
