Hi, I'm South African, my girlfriend Australian, living in Bali, Indonesia. We recently purchased a couple of locally-made MTBs. The brand is Polygon. They're surprisingly decent bikes. We're coming back to Cape Town soon for 3 months and, ideally, would like to bring the bikes with us on the plane to use while we're there. Can anyone enlighten me as to what, if any, duty/vat implications there are for doing this? The alternative is to buy while we are there but we would much prefer to bring our own bikes, Thanks Nick
