The Phelon & Rayner 1.75 hp was a British motorcycle made by Phelon and Rayner (P&R). There was only one P&R model which had a 1.75 h.p., 260 cc. engine with 66 x 76 mm bore and stroke fitted in a standard bicycle type 28" frame (with 23" and 26" options). It was fitted with a surface carburettor, single speed friction disc transmission, a 9 pint combined oil and fuel tank, bicycle pattern front forks and 28" x 2" wheels (except for the 23" frame option that had 26" x 1&5/8" wheels). The colour scheme was black frame and mudguards with an aluminium enameled fuel tank with coach lining.〔"The Panther Story" by Barry M Jones, Panther Publishing Ltd.〕 A prototype was based on a patented design.〔GB Patent No. 3516, "Improvements in Motor Vehicles, Tricycles and Similar Vehicles", Joah Carver Phelon〕 The key innovation was to replace the frame's front down-tube with a four rod frame that held a small de Dion type engine. This 'Sloper' engine was the hallmark of P&M / Panther motorcycles until the last Model 120 more than sixty years later. Production machines of the same design as this prototype were hand-built in 1901 through to 1903.〔 ==Development== This model was the first motorcycle produced by P&R.〔 1900 prototype built based on a patented design.〔 The key innovation was to replace the frame's front down-tube with a four rod frame that held a small de Dion type engine. This 'Sloper' engine was the hallmark of P&M / Panther motorcycles until the last Panther Model 120 more than sixty years later. Production machines of the same design as this prototype were hand-built in 1901 through to 1903. This prototype machine also featured a further patented innovation:〔GB Patent No. 8937, May 1901, Joah Carver Phelon〕 a half compression device to make starting easier. This featured on all future heavyweight P&M / Panther motorcycles.〔 1901 was the first year of production of the Phelon and Rayner (P&R) 1.75 hp. It had a 1.75 h.p., 260cc. engine with 66 x 76 mm bore and stroke fitted in a standard bicycle type 28" frame (although 26" and 23" became options, presumably due to experience showing 28" was too tall for a motorised bicycle). It was fitted with a surface carburettor, single speed friction disc transmission, a 9 pint combined oil and fuel tank, bicycle pattern front forks and 28" x 2" wheels (although smaller wheels were fitted to the smaller frame). The colour scheme was black frame and mudguards with an aluminium enameled fuel tank with coach lining.〔 1902 was the second year of production of the 1.75 hp. It was fitted with a surface carburettor, single speed friction disc transmission, a 9 pint combined oil and fuel tank, bicycle pattern front forks and 8" x 2" wheels (although smaller wheels were fitted to the smaller frame). The colour scheme was black frame and mudguards with an aluminium enameled fuel tank with coach lining.〔 Photographic evidence indicates it was available with (carbide) lights. 1903 was the last year of production of the Phelon & Rayner 1.75 hp.〔 Photographic evidence shows it was used to pull a trailer chair. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phelon & Rayner 1.75 hp」の詳細全文を読む スポンサード リンク
