All Metal Velocipede By: A. Dubois, Avenue de Paris # 104, St. Denis, France, Circa 1870

The "All Metal Velocipede" was the trade mark of maker A. Dubois of St. Denis, France who promoted them as superior in strength. This method of wheel building preceded the tension wheel. This type of construction resembles a wooden wagon wheel where a wheel is kept straight or "true" by the force of compression. This differs from the later style of tension wheel , where spokes are threaded into a hub or nipple, and hold a wheel true by adjusting spoke tension. Modern bicycle wheels are tension wheels.
