The update to the 7000 model is a real winner. A HUGE motor gets even bigger and they have upgraded many drive system parts!
Excellent unit but kind of confusing in the lineup. They have the Proform Pro 7000 but the Pro 4500 has a stronger motor and some better drive system features. We suppose they took the time to refresh the Pro 7000 so they could solve a channel conflict issue but that would be the only logical reason why they did it. Proform is making an excellent $2,000 unit.
