Report from the Stanley Show 1902
The Crypto Works Co., Ltd., have five motor-bicycles on show. These include three Crypto 2.25 h.p. and one 2.75, h.p. machines, and a featherweight, fitted with the Clement-Garrard motor. The engines of 2.25 and 2.75 horse-power are fitted in a vertical position, right in the centre of the frame. An ingenious switch and combined exhaust valve lifter is good. A special Longuemare carburetter is used, and the Lincona belt fitted. The petrol tank is of neat design and large capacity. The control levers are within easy reach of the rider's hands on the horizontal tube. A silencer of large dimensions is used, and wheels, hubs, and all frame parts are of extra strength. Dunlop or Clipper tyres are fitted at option, and the price of the 2.25 horse-power is £50, and the 2.75 £65. A Bowden back rim and a lever front rim are fitted, and the finish of the exhibit leaves nothing to be desired.

Report from the 1903 Stanley Show
The exhibit of motorcycles on the Crypto Works Co.'s stand will consist of three specimens of two different model motor-bicycles, and two specimens of the Crypto tri-car.
The Crypto tri-car is a practical light motor vehicle for two riders. The frame is built of large diameter tubing, and the steering is of the differential type. The special features of this machine are its expanding band brakes on the front wheels, the length of the belt drive, and the strong construction throughout. The front seat of one specimen to be shown has a very fine coach-built bucket seat, and the other is of upholstered cane; 2.5in. tyres are fitted to the back wheels; the engines used are 3.5 h.p. M.M.C.
The new pattern Crypto bicycle, as illustrated herewith, has been designed to fill the present-day requirements for a comparatively light bicycle, with ample engine power. The frame, which has been duly protected, is exceptionally strong and symmetrical. The engine fitted is a 2.5 h.p. Peugeot. The whole machine weighs 100 lbs.
The other motor-bicycle will be of the now well-known Crypto type, fitted with a 3.5 h.p. M.M.C. engine. This machine is specially suitable for racing and for trailer and fore-carriage work. This exhibit will be at the Stanley Show, and we shall further illustrate the firm's novelties in our Show Special.
