The small motorcycle on the front of the Jeep is a paratroopers collapsable motorcycle and was called the 'Wellbike'. It was dropped from the aircraft in a cannister and when removed, the seat pulled upwards and a pin was pushed through the down tube to lock it in place, the long handle bars wer lifted upwards and also pinned to retain them. It was the forerunner to the 'Corgi' which was the domestic version sold to the domestic market just after the war. I had a 'Corgi', re-built it and eventually used it for a short while on the road... didn't go, didn't stop and left one feeling very vulnerable but it must have been a real boon to a paratrooper.
