Once it's packaged up in a cardboard bike box we're talking 10kg...
You might be talking 10kg, but international shipping deals in a weird non-physics unit called Volumetric Weight. It makes a kind of sense that it's cheaper to ship a 16" cube of Tungsten rather than 650 cubic yards of Silica Aerogel, even though each weighs 1 ton. In the case of a boxed up bicycle, the Volumetric Weight comes in at about 60-100kg depending on how much you dismantle it to get it in the box.
