Information about Olympia bicycles
Olympia bicycles are as good as any, and the company has been doing for about 100 years longer than any you mention.

Having said that Olympia produce good bikes, they have a different brand for pro-level equipment: Scapin, one of which I am privileged to ride.

I gave an Olympia to my brother-in-law, three years ago. He's been riding it 500 km per month ever since without problems.
