Pros & Cons


  • The bike is extremely quiet; even when at higher levels of resistance, the only thing you’ll hear is a bit of rattle from the ventilator when you level off.
  • The seat is comfortable but not made for long-term use as it begins to lose its firmness after about an hour or so.
  • The pulse monitor is very accurate, even at higher levels of resistance.
  • The display is easy to read, and the data it provides helps monitor your progress.
  • It’s very versatile and can be used for cycling, running, or any other cardio regimen.


  • The bike is hefty, weighing about 100 pounds, which isn’t a problem when you’re doing stationary cycling, but if you’re exercising on it regularly, then the weight will play a factor in your back and lower back pain.

  • The seat can be a bit uncomfortable at times, especially if you’re tall.
