Motorped and Simplex Motorcycles

Patrick Engineering of Birmingham.

  • The company produced a Simplex motorcycle power unit from 1919 to 1922.

This was a strengthened bicycle fitted with a 105cc two-stroke engine. The unit was sold separately, to be fitted to any gents' or ladies' bicycle. It fitted above the rear wheel which it drove by chain.

Motorped was a motorcycle produced from 1919 to 1922 by Patrick Engineering of Birmingham.

A two-stroke auxiliary engine was fitted above the rear wheel of a strengthened bicycle to create this machine and it was available in either ladies' or gents' versions. It had a 104cc engine with a horizontal cylinder that had the fuel tank above, magneto ignition, Amac carburettor and drove the rear wheel by chain. A plate clutch was optional.

The power unit was also available separately, as the Simplex, and could be attached to any machine.

The Motorped is new in name only - this being the title the makers of the Simplex cycle attachment give to the complete cycle built by them, and equipped with their power unit. One of the earliest units made for this purpose, the Simplex is a "flat" two-stroke single of fairly conventional design. A tiny plate clutch is optional this year, and a means is provided of holding the plates permanently apart should the need arise on any occasion for pedalling home. Merely an ordinary pedal machine of strong build, the cycle itself may readily be re-converted to a "one rider power" mount.

With clutch the Motorped sells at £42, without at £37 16s.
