Coventry Acme Motor Co., Ltd., Earlsdon, Coventry.

Designed for use with a sidecar, the Acme is fitted with an 8 h.p. J. A. P. engine, Sturmey-Archer gear box, and chain and belt transmission. The sidecar lugs are built integral with the frame, and the steering head and lugs are steel stampings. Lubrication is carried out by suction through a sight feed lubricator, which is supplemented by a hand pump carried on the off side of the tank in a position convenient to the driver's hand. Brampton spring forks are fitted as standard, and wide mudguards with deep valances give ample protection to the driver and machine. The tank is of large capacity, accommodating 2 1/3 gallons of fuel and 3 1/3 pints of oil, so that on tour there is no necessity to be constantly filling up.

So successful has this model proved during the past season that it has been decided to supplement it by a similar machine with a 5-6 h.p. J.A.P. engine, this being regarded as a dual-purpose mount. The engine has a bore and stroke of 70x85 mm., giving a cubic capacity of 654 c.c. In other respects the specification is identical with that of the more powerful model, and the same finish of black with a grey-panelled tank lined with gold is adopted. The two machines are known respectively as Model A and Model B, the price of the latter, complete with sidecar, spare wheel, and carrier, being £210 18s. An exceptionally long wheel-base is a feature of both Acmes that is not without advantages.
