| Daroga,
I sell these things, and to be honest, the 5.17i is the trickier elliptical to assemble when you compare it to other models. You may want to go ahead and have them delivery and assemble it for you. If you try it yourself, and end up breaking something or accidentally slicing the data cable, Precor will not honor the warranty, or so I've been told.
For the height, I'm 5'11, and when I'm on the Precor, my height bounces between 6'9-6'11. The cross ramp does not make you higher, contrary to popular belief, and the 5.17 ramp doesn't going higher then the other ones anyways.
good luck |
