The result of over ten years of research and development, Keiser M3 Plus is one of the highest quality indoor cycling bikes available. This machine matches revolutionary magnetic resistance technology with a minimalist yet extremely sturdy design that provides a smooth-as-silk ride.

If your goal is to lose weight or get into top fitness, the M3 Plus will get you there. With 24 levels of magnetic resistance this indoor bike provides as challenging a workout as you can handle.

The major advantages of the M3 Plus are the revolutionary magnetic resistance system, near-silent drive belt, backlit computer display, and fore and aft handlebar adjustment. The design of the bike looks as if Keiser stripped away any unnecessary components and left simply one of the most high-tech yet user-friendly exercise machines.

The Keiser M3/M3+ is NOT designed with a freewheel, but a fixed gear system. When the flywheel is in motion, the pedals will also be in motion. Never remove your feet from the pedals while in motion as serious user injury may occur. Always secure the pedeal clip strap by placing your foot on the pedal and in the toe cage. Locate the strap and pull up on it to tighten. It should be snug but not too tight to cause discomfort.
