Wolf Engineering Co., Ltd., Wolverhampton.
No less than seven different models of motor bicycles are shown by the above company. Standard Model A is a 1½ h.p., 63 X 66 mm., single-cylinder, accumulator and coil ignition, Stevens carburetter, 6 to 1 gear, rigid frame and forks, sold at a very moderate price. It is fitted with round belt.
Standard Model B is a 2½ h.p., similar to the above, but with Bosch magneto, round belt, weight 80 lbs. The Royal Model A, fitted with the same size engine, accumulator ignition, with one hand and one foot brake instead of two rim brakes, weight 83 lbs. The Royal Model B, fitted with a similar engine, with Bosch magneto, weight 85 lbs. To the above Druid spring forks are fitted as an extra.
The Grand Model B is quite a new one, 76 X 76 mm., 2 h.p. engine, Bosch magneto, Druid spring forks, weight 92 lbs., frame exceptionally low. The carburetter is of particularly neat design, fitted with a bayonet-jointed float chamber top, and a very accessible jet, while a means is provided of injecting petrol by a pipe fitted with a tap leading straight from the tank into the compression tap. The stand fitted to this and to other models is a neat one, inasmuch as it is rigid, and is released by a catch which can be operated by the foot. A neat cut-out is also operated by a clip situated close to the rubber footrests. The machine is a thoroughly practical lightweight mount.
