BSA AIRBORNE 1st PATTERN:
ORIGINAL MANUFACTURER’S DRAWINGS
The overwhelming majority of the 70,000 Airborne bicycles manufactured were the later model with a single seat tube.
This is the first design, a lightweight version with a twin seat tube. Few were made. It was built in a hurry, to strict weight criteria. Like many innovations introduced during the war, in reality it was a prototype, and it proved to be too weak to withstand rough use. So the 2nd Pattern did not feature the unique duplex seat tube, which meant that it weighed more but was stronger.
1942 WW2 BSA Airborne Bicycle, 1st Pattern:
Early Twin Tube Model
Frame Number R1422
BSA Model 40 Saddle
War Grade Tyres: Michelin ‘WD’ & Avon Avebury
(Now sold)
This BSA Airborne was repainted many decades ago and has all the correct original parts.

SEAT TUBE MOUNT & BSA ‘MODEL 40’ SADDLE
The early model’s double seat tube can not be easily discerned in a side profile picture. But shape of the top of the seat tube can be easily seen from a distance. The seat tube mount is markedly different. The saddle actually fits into an extra tube fitted behind the twin seat tube, a radical departure from conventional bicycle design of the time.

WAR GRADE TYRES: MICHELIN WD & AVON AVEBURY
A pair of good War Grade tyres is included. I’ve kept normal tyres on it for riding. The War Grade tyres are fine for display but I don’t want to damage them riding so they are not fitted. The Michelin says ‘WD’ on it.
