Phillips Cycles Ltd. was a respected British bicycle manufacturer based in Bridge Street, Smethwick, England.
The Rex engine at 6:1 compression has no bhp given but carries a 12-millimetre Bing carburettor to the aluminium barrel with sleeve liner in conventional fore & aft porting layout.
The crankcase cavity unusually extends all the way to the back of the motor to include lubrication of the reduction gear and its bearings by the induction gases.
Mounted on the end of the output shaft with the sprocket inboard, the tiny 2½" Rex dry clutch is a particularly frail pull-operated device and typically responsible for the final demise of most machines.
