What every best Exercise Bikes has:
- Quiet resistance.
- Well-calibrated resistance levels.
- Workout programs.
Magnetic resistance is precise and quiet. The Keiser M3+ uses a precise magnetic resistance system with 24 different gears, or tension settings. Bicycle enthusiast "Dave" at DavesCheapBikes.com writes, "The resistance adjustment is so exact, you can just click it into the correct level of resistance every time instead of 'guessing' what level of resistance you should have it set at, like you do with the cheaper, pad-resistance systems." The bike is also reported as exceptionally quiet, for those who want to listen to music or watch a movie while they pedal away. Users have a full range of settings available with the adjustable pedals, horizontal and vertical adjustments on the handlebars, and a four-way adjustable seat.
Computer display is easy to read. The M3+'s backlit LCD screen displays six different statistics at one time, providing users instant feedback without having to scroll through data. "I love that it calculates your power output," says DavesCheapBikes.com. "Typically, only pro cyclists get to see their wattage, and the Keiser M3 Plus lets you see exactly how hard you are working out and allows for advanced fitness." The M3+ is capable of linking with a separate chest-strap heart monitor, but doesn't include a built-in heart-rate monitor. Users say the seat is very comfortable. The seat and handlebars are fully adjustable, meaning that it can accommodate a wide range of user heights -- a rarity among this type of bike.
Gym-grade durability. As an upright bike commonly found in fitness centers, the Keiser M3+ is a solid machine built for heavy-duty use. "Developed by one of the top providers of commercial workout equipment, the M3 is designed with all of the bells and whistles that coaches across the country have consistently asked for, along with the durability to withstand daily, abusive workouts, by hundreds of sweaty gym members," says DavesCheapBikes.com. Keiser's comprehensive warranty is one of the best: 10 years of protection on the frame and three years on the mechanical and electronic parts.
