Lot 338: A circa 1891 Pneumatic Tyred Safety Bicycle. One of the earliest pneumatic tyred bicycles extant because original examples of early Pneumatics are extremely rare, and doubly so in this example because it is offered with an original 'Bartlett' tyre and tube. Indeed, this tyre was probably the first practical, easily detachable, bicycle tyre in history, yet the tyres quickly became obsolete, assuring that many of these bicycles were abandoned. The rims represent Bartlett Clincher Rims of the 1890 pattern as per their patent No 16,783. The rim was also patented in America in 1891, Numbered 448,793. (Please see this image via the internet description). Manufactured by the North British Rubber Co. of Edinburgh. It was the first type of tyre to be easily detachable from the rim, and the first serious competitor for Dunlop. By 1892 these tyres were fitted with all-rubber inner tubes, rather than the earlier tube with a canvas liner and a large one-way valve, an example of which comes with this bicycle. The front wheel is 30-inches, the rear 28-inches. A standard 28 x 1?-inch beaded edge tyre is now fitted to the front rim, making the bicycle complete and rideable. (Instructions can be provided on how to stretch a new tyre onto the rim). The frame is 20-inch with a sloping top tube, remote steering head on conical bearings and sweeping handlebars. The saddle cover, handlebar grips, pedals and plunger brake are of the period style, but it possesses its original spokes, mudguards and stays. There is some pitting to metal parts. Generally in very original, oily rag, rideable condition.
