The Keiser M3 was designed with your clients, your instructors, and your club in mind. Experience the new way to indoor cycle. The M3 will change the way you think about indoor cycling.

Flywheel Weight
The 7.5 lb flywheel is extremely light as far as flywheels go. However, Keiser uses magnetic resistance instead of a crank so it won't affect your ability to get a lot of resistance.

Pedal Type
The dual sided pedals feature Toe Clips on one side and SPD clips on the other. Toe Clips are the most secure way to keep your feet on the pedals, but are hard to get out of quickly. SPD clips are the safest way to keep your feet secured to the pedals, but require you to have a special type of shoe.

Seat adjustment
The ergonomic bike seat adjusts horizontally and vertically with pre-drilled holes and a locking pull pin. This amount of adjustability is usually enough, but if you're particularly picky or want an absolutely custom fit, you'll want a fully adjustable seat.

Handle Bar Adjustment
The multi position handle bars let you ride in a variety of positions from a normal seated position to a crouched sprint to a standing hill climb leaning out over the handle bars. The handle bars adjust vertically only and uses a pull pin and hole locking system, so if you're especially short or tall, or picky about your fit, you'll want to look for something that adjusts in more directions.
