Red side rails and a matching light strip mark out this 2-in-1 treadmill, but the useful part is the 4.75 HP motor behind them. With the risers raised the belt runs 0.6 to 10.5 mph; folded flat it becomes a 0.6 to 3 mph under-desk walker controlled by remote. The belt spans 49 in by 20 in over five layers of shock absorption. An LED touch screen handles speed and volume and reports pulse, calories, distance, time and speed. Unfolded it occupies 58-in W by 31-in D by 47-in H, folding to 6.5 in. Steel, ABS, PVC and MDF bring the total to 106 lbs, rated for 265 lbs of user weight. Transport wheels make repositioning simple after a session.
