Where are the best bike shops in Sydney?

Which bike shop is the best in the Sydney area? I have noted down a few, but I was wondering if some are better than others? or if people have recommendations for certain places?

They specialise in second hand dutch bikes, as they see them as sturdy reliable way to get around any city.
