Keiser M3i with M-Connect

A true road-bike indoors, the Keiser M3i has a unique design and makeup that you will only find on Keiser bikes. Its sporty yet ergonomic seat is adjustable, which allows for a better seating position that fits users from 4"10 to 7 feet tall. Its Bluetooth technology allows you to train individually, or interactively with friends and family in a group setting. The Keiser brand, German-designed and American-made, is known for quality manufacturing.

The Poly-V belt is the key to Keiser's drive-train design because it transmits very high loads over very small pulleys, achieving a good road-bike experience:

• Without a perimeter-weighted flywheel
• Without a more complicated drivetrain
• Without the unnecessary noise and vibration of a cog belt

The belt's pre-tension design requires zero adjustments, and the M3i drivetrain requires no maintenance other than routine inspection.
