1904 Report. 'A very neat and well-designed bicycle motor is made by the Noble Motor Co., Blackfriars-road, London, in which both inlet and exhaust valves are mechanically operated, a feature which the firm claim to have first introduced in the manufacture of small cycle-motors. By its use the engine is rendered very silent and positive in its action, and by means of a relief cam the starting effort is greatly reduced. The valves are arranged side by side and worked by tappet rods actuated by a train of gear wheels worked from the half-speed shaft. The valve boxes are cast from the cylinder and bolted by means of a single bolt, the joints being made with two copper-asbestos washers. Two fly-wheels of large diameter are fitted, which assist materially in the smooth running of the motor. Perhaps the best feature is that there are only two levers needed for its control, one governing the sparking and a throttle fitted to the mixture supply pipe. The smaller sizes are air-cooled, but if required can be supplied with water cooled system.'
Post-WWI (?) The company undertook examinations of motor vehicles on behalf of the Underground Group of companies.
