Again, the key innovation of this technology is that when he wants to go fast, he just grabs the levers near the pivots and goes through a big angle every stroke, and as the going gets tougher, he just slides his hands up the levers, creates more torque, and kind of bench-presses his way out of trouble through the rough terrain.
这项科技的核心创新点在于 当他想走的快点，他可以握住靠近抽心的位置作大角度的推动 当进入较糟的路面，他只需要握住握杠的上部 就可以推动较大的扭力 让他自己推离不平地地形
