What our customers say

"What's nice about Keiser is the fact that it's compatible with multiple apps that you can download onto your IPAD. With other bikes, you're limited to using their software."

  EASY TO ADJUST 

FOR A PERFECT FIT

Our unique V-shaped frame allows the M3i to mimic different road bike frames.

As a result, the M3i can accommodate riders from 4'10" to 7' tall, up to 350 lbs.

Four-way seat and handlebar adjustments make it easy for almost anyone to find the perfect fit.

DESIGNED TO PERFORM

BUILT TO LAST

COMMERCIAL GRADE

The M3i is the cycle of choice for:

  • Gyms both large and small
  • Cycling studios
  • Professional and Olympic Athletes
  • Hospitals
  • Police and Fire departments
  • Every branch of the US Military

Less corrosion. Less maintenance.

Our rear-mounted flywheel is out of the "sweat zone," and the contoured frame directs sweat away from critical parts. Less corrosion, less maintenance.

Built for durability and longevity.

The M3i's Poly-V belt is quiet and maintenance-free, producing a smooth ride every time. Automotive manufacturers trust the same Poly-V belt for its durability, and longevity.

Tested in the gym so you can trust it in your home. 

What our customers say...

"My Keiser M3i is built like a tank and I love the ease of changing gears. It is whisper quiet and very comfortable. I plan on this bike lasting for years of happy exercise!"
