What is the name of the manufacturer of this Chinese made bicycle? I have a Trac (no 'k') Forever 200 bicycle from China (complete with Chinese writing on it). Any idea who the manufacturer is? Is this bike common in China? I can't find anything online about them.  Thanks.

  There are many places across Shanghai to pick up classic Yongjiu (Forever) bikes.
