Bergmönch is German for "Mountain Monk" -- you carry the bike up the mountain and then ride it down kneeling for the descent like a monk. Mountaineering revolutionized, the Bergmönch can be folded into a backpack that can be conveniently carried uphill and then folded apart to reveal a bicycle you can ride downhill, relieving your joints and muscles the arduous task of the descent. This riding position and the different-sized wheels ensure superb handling and safety while achieving a perfect compromise between compactness in uphill mode and comfort downhill.
