"STARLEY BICYCLE, Ca. 1887 U.S.N.M. No. 218218... photograph No. 811-D; plate 17, a. This "Psycho" bicycle, built by Starley Brothers, St. John's Works, Coventry, England, is of the improved cross-frame, safety type, with a crank-bracket stay, a stay between the steering head and the top of the saddle post, and a pair of stays from the rear end of the rear fork to the top of the saddle post. In 1887 the manufacturers of this machine were awarded a gold medal at the International Exhibition at Toulouse, France. The frame is of metal tubing, the handle bars are metal with wooden grips... and the Brooks saddle, of leather over coil springs, is adjustable both vertically and fore and aft. Each wheel... has a thin solid-rubber tire and 48 radial wire spokes. The rear-wheel sprocket, on the right side of the wheel, is driven by a block chain from the front sprocket, which is equipped with pedals adjustable in throw from 5 1/1 to 6 1/2 inches. The chain tension is adjusted by moving the rear axle backwards or forwards in slots at the rear end of the rear fork. There is no coaster attachment, the pedals always turning while the bicycle is in motion. Oil cups are... in the hub of each wheel."
