Transformer treadmills represent a whole new category of folding treadmills and the Osprey is the best value in it"s class. Through our ingenious design, this amazing space-saving treadmill can morph into a powerful, non-folding style running machine that can take a pounding. The Osprey is no bare-bones entry-level treadmill. This machine can handle heavy-duty running or walking and does NOT feel like a folding treadmill at all. Unlike other "hinged" folding treadmills, the Osprey looks and feels as good as any treadmill you have ever used. Runners will love the one-touch speed and incline buttons as well as the progressive shock absorption deck that delivers just the right amount of flex based on your speed and body weight.
