the way I see how it works is since he's not attached to the bike, his momentum is still going directly forward and not turning with the bike. that way once the bike is done the first 90 he can push it back straight with his body. I dunno how else that would work
I saw this on tv a while ago, or something close. I would love to see one of these big whips explained by a physicist. I think it would be more of the axis of rotation being changed irregularly than the laws of inertia being thrown out.
Not 100% sure how this works but I know it has to do with the spinning front tire along with his body acting on the bike. The wheel acts like a gyro while spinning in the air and helps point the bike in the direction the wheel is turned.
I think it has something to do with the spinning front wheel being turned. Its like when you hold a spinning bike wheel and when you move it around it resists or moves farther than you meant to move it. I probably didn't explain that very well but I'm sure somebody knows what I'm talking about
I'm not an xtreme fmxer yoo, but I think it helps a lot bringing it back when they just give it full throttle on the way back. If you're just airing straight it'll bring the back wheel down a lot and help being all gyroscopy and shit.
