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.
