The giant pedaling bike that my friend transferred to me, but the flywheel at the back is the giant logo black, is it normal? I thought it was the SHIMANO sign.
the flywheel of a single-speed car can be divided into two types: one-piece flying and split flying. One-piece flying is that the flywheel and the flower drum are riveted together as lz said, while the giant uses SHIMANO, Jiuyu and Feimin. Shimano uses its own trademark, while Jiuyu and Feimin stick the trademark of Giant.
