Bicycle : transportation for improvised explosive device

Standard men's bicycle used to transport a directionally focused charge IED (REL46089.002).

This standard men's bicycle was used to transport an Improvised Explosive Device (IED), the first Directionally Focused Fragmentation Charge (DFFC) recovered in Uruzgan Province. The device was captured in September 2010 in Tarin Kot together with an improvised detonator, a 6 D cell battery power source and a radio control dual tone multi frequency decoder. The main charge was a home made explosive designed to project fragments of metal in a focused direction, most probably towards vehicles. The bike was abandoned by its rider when he approached a security check point.

IEDs have caused more casualties to Australian service personnel in Afghanistan than any other weapon. They usually consist of four principal components arranged in an electrical circuit: a trigger or switch, a power source, a detonator, and a main explosive charge. The main charge often contains metal fragments to increase the blast effect.
