Form and function meets compactness and economy in Kettler's new Berlin series of treadmills. The S2 is a feature-rich and durable exercise machine in a strikingly handsome exterior that is entirely worthy of its German namesake, and designed with the space and budget-conscious in mind, yet sacrifices none of the luxurious features that such modest ranges usually do. With a powerful motor driving up to 18km/h speed and 15% incline, with a generous running surface of 140cm wide, and a 7" LCD display, along with a unique honeycomb suspension system, The Kettler Berlin S2 is poised to impress and amaze.
