Bicycle moves

This principle is easy to imagine if you imagine that you are going on a bicycle from a steep descent and physically do not have time to turn the pedals with the desired speed. It lasts so long until the bicycle moves from the hill and does not drop the speed finally so that the rotation of the pedals was again required to continue the speed movement. The front -wheel drive of the Christini motorcycles acts according to the same principle: under standard conditions of movement, the front wheel drive lags behind the rear, and therefore does not use.
