I guess if you managed a bike shop, like I do, and dealt with the same number of customers (often older) transitioning from jogging to cycling because of the reduced impact on their knees and ankles, then you'd probably understand. You don't have to use your legs to instantly, and repeatedly, stop all your momentum, and then thrust your body weight into another direction. I could elaborate, I suppose, but let's just say that jumping and cycling affect your legs in completely different ways, and knee injuries seem to be way more of a hindrance to jumping/jogging than cycling.
