a collapsible motorbike that could be dropped into action behind enemy lines before. The light*weight issue (which is more or less a proto–Monkeybike) was designed by the British Inter Services Research Bureau, which was based in Welwyn, appar*ently, to give paratroopers increased range and manou*ver*ab*ility behind enemy lines.
Naturally the bike had to be stripped down to the bare essen*tials in order to fit inside the standard drop container and so came with a single rear brake, no suspension or lamps. The fuel tank had to be pressurised by a hand pump, appar*ently, but gave a pretty decent 90 mile range at 30 mph.
