I bought this bike in China when I was on vacation. He was only a Giant Bike Dealer. He had different types of folding bikes from Giant. There were a few that were single speed and even a halfway that is different than the States. It had a rounder frame instead of the square shape tubing. The single speed folders were dirt cheap, I should have picked one up.
Bike Specs. It has the Oval tube frame made from 7005 ALUM, SRAM X-7 rear derailleur, Tektro brake, quick release hubs, and some other unique stuff like an integrated bell on the left brake lever. It weighs around 11 kg. I'm trying to dig more info about the bike but most of it is in Chinese.
