Alldays & Onions Motorcycles

Alldays & Onions built motorcycles in Sparkbrook, England from 1903 to 1915. Models included the Villiers-powered Alldays Matchless (no relation). After 1915 they moved to a new factory in Small Heath and marketed under the Allon brand up until 1927. Allon models included a 539cc JAP V-Twin model.

The Alldays name dates back to the 17th century, and the firm merged with JC Onions in 1885 to build all manner of machinery including numerous bicycles and tricycles, and branched into automobiles in the early 1900s. During WWI they built mostly motorcycles, returning to cars on cessation of hostilities. The company changed its name to Alldays Peacock which was acquired by the Spire Group in the 1980s.

This firm have an extremely well-designed 3 H.P. motor-bicycle, up-to-date in every respect. The valves are mechanically-operated, and the engine is provided with a ball bearing crank shaft. The magneto is driven by an enclosed non-stretchable chain. The engine is free, the clutch and two-speed gear being in the hub of the driving wheel. The belt pulley is adjustable so that the correct tension can be maintained on the belt without the risk of unduly straining the bearings. The frame is low, and spring forks are provided. Ample petrol and oil tanks are fitted, a great point from the tourist's point of view. The machine is a very quick starter and the "pick up" on either gear is gentle. It will be noticed that the firm only manufacture this one size of engine, so that all the attention in the countless details that go to make up a perfect design has been bestowed upon the one model - a fact which we think the purchaser will appreciate.

Interesting features which should not be missed on the Allon exhibit are the horizontally split crank case and the method of casting in the oil leads. Cylinder and top half of crank case are cast together, and the engine unit is held in the frame by lugs placed above the crankshaft centre, so that it is only necessary to detach the lower half of the crank case in order to remove the crankshaft, connecting rod, and piston.

A large bore steel oil pipe leading to each crankshaft bearing is cast into the crank case so that only one oil union is necessary and a multiplicity of bent tubes is avoided. Larger bearings have been fitted, and the piston has been modified to obtain lighter weight and better gas flow.

Several detail modifications are incorporated, including wider mudguards and longer wheelbase. A Villiers flywheel magneto is now fitted, thus avoiding an auxiliary chain drive which might cause noise. This ignition set may be converted to provide current for lighting at a very moderate cost. Sensible legshields are included in the specification, and an unusual feature is the fitting of the Allon special band brakes to both front and rear wheels.
