LifeFitness LifeCycle Exercise Bike Upright 9100

Pros: Smooth, quiet, reliable, great programming, US manufactured
Cons: a little more expensive than some other brands.

I have a Lifecycle that is one of the residential versions of this bike (it is a slightly older model now). They are the best. I sell fitness equipment for a living and have been doing so for ten years, selling a wide variety of manufacturers. None come close to Life Fitness's quality and design. This is one product I can sell to anyone without worry; it is reliable, smooth, easy to use, and built like a tank. It is also the only high end bike that I am aware of that is still made here in the U.S., and you can see the craftsmanship difference. Do yourself a favor - regardless of whether you are buying a bike, treadmill, or elliptical trainer, get a Life product and I guarantee that you will USE IT!
