On a bike, there are several wheels at the chain transmission's level and several gear wheels at the back wheel's level.

We choose to go by bike with the 32 cog front chain wheel and the 16 cog gear wheel. When the pedals have done 1 complete turn, the wheel has also done
turn, because it is interdependant with the chain transmission.
So, the chain has
links.
The gear wheel has done
turns (16 cogs x 2 = 32 cogs).
The back wheel has done
turns because it is interdependant with the gear wheel. |
