““It is not uncommon for the cyclist, in the first flush of enthusiasm which quickly follows the unpleasantness of taming the steel steed, to remark, ‘Wheeling is just like flying!’ This is true in more ways than one.… Both modes of travel are riding upon the air, though in one case a small quantity of air is carried in a bag and in the other the air is unbagged.… To learn to wheel one must learn to balance; to learn to fly one must learn to balance.””
