Bicycling is the nearest approximation I know to the flight of birds. The airplane simply carries a man on its back like an obedient Pegasus; it gives him no wings of his own. – Louis J. Helle, Jr., Spring in Washington

All creatures who have ever walked have wished that they might fly. With highwheelers a flesh and blood man can hitch wings to his feet. – Karl Kron, Ten Thousand Miles on a Bicycle
