Hi Ireland,

Bicyle Bombs, were first used in Malaya, so a link from Afghanistan to Singapore is not all that surprising. The counter-measure in Malaya was bicylcle parks - anyone coming into a town or village had to stay with their bicylce for a time - as the fuses used in those days were chemical activated detonators (pretty unreliable wrt time) the guys with the bombs used to get extremely agitated and very easy to spot. They gave up using them in the end.
