General Description
(Acknowledgements to Mark Daniels and "Buzzing").
The single-speed Panda Mark 1 and 2 utilised what probably became the last manufacturing installation of the 49 cc German Rex cyclemotor engine, which first appeared around 1950 in the form of a front-mounted, belt-driven cycle attachment, the strong but basic Panda frame being specifically built to house the motor.
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! This results in a reduced scavenge pressure. 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.
The Panda has a 'grip-locking' clutch lever and a carburettor set-up that provides a very reliable and steady tick-over. The rear brake comprises a back pedal Perry Coaster hub and a conventional bicycle-type hub brake, handlebar lever operated for the front brake.
Mark 1 version had no suspension but the mark 2 had telescopic front forks, larger headlamp and deeper valanced rear mudguard but retained the solid rear frame.
The electrical system comprised a Miller flywheel magneto with lighting coils.
The final Panda mark 3 was simply an imported French Mobylette made by Motobécane badged as a Phillips. It had nothing in common with the previous home-produced models.

“The man who would change the name of Arkansas is the original, iron-jawed, brass-mouthed, copper-bellied corpse-maker from the wilds of the Ozarks! He is the man they call Sudden Death and General Desolation! Sired by a hurricane, dam’d by an earthquake, half-brother to the cholera, nearly related to the smallpox on his mother’s side!”

“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
