Gardo,
How many times do we have to go over this?

The DF is manufactured by Ningbo Dongfang Lingyun Co according to the plate on the frame. http://dfly.en.alibaba.com/aboutus.html

The Heist is manufactured by Qingqi Rhon http://www.motor-rhon.com/

Both are large Chinese companies and these bikes are completely sourced in China.

As far as DF or Heist staying in business, that is a unanswered question. A person probably shouldn't buy either bike if they are depending on the company staying in business. They should buy a Honda, Yamaha, Harley, etc.
