I am selling my Keys Fitness 4500 T model treadmill for $375.
It has a 2.5 continuous HP motor, speed toggles on side bards, elevation toggles on side bards, fold up 2 stage shock design, 5 window LCD display with blue black light. This treadmill was originally purchased 8 years ago for $1,499.99 and has only had light usage since then.
It has all it's original parts and is still in excellent working condition. I would love to keep it, but with my girlfriend moving in, we need the extra space.
