These Chinese roaster bikes (Flying Pigeon, Forever, Phoenix etc) may be heavy and with low end components. They are, however, very strong and serve their purpose as transportations.

They are still being made and in China you can buy (wholesale) for about $50 - 60 each if you buy 150 - 200 units.

Someday I will get one here in the USA and change the rear hub to a coaster brake or better yet, a 3-speed coaster brake with 40h.
