chain

8 Episode Mentions
Too Afraid to Ask

A chain is a series of linked metal pieces that help move the bike or car. It’s like a belt but stronger, and it needs to be kept tight and oiled so it doesn’t break.

Technical Definition

The drive chain is the metal link that transmits power from the engine’s crankshaft to the rear wheel on motorcycles and many cars. It must be properly tensioned and lubricated to prevent failure during high‑speed operation.
