I'm looking for at least 5 units of a high-performance treadmill for our gym. Key specs include a powerful motor, adjustable speed range from 1-25 km/h, and incline options from -3 to 18 levels. Additionally, it should feature a 9.6-inch LED display that shows essential metrics like time, distance, calories, and heart rate. A robust build to support a max load of 200 kg and a running area of 62 x 170 cm is crucial. Please provide details on pricing and lead time.
