<human>:  How do I repair a bicycle chain?
<bot>: First, you'll need to locate the damaged link in the chain. Use a chain breaker to remove the damaged link, then connect the two ends of the chain together with a new link. Make sure to align the pins properly before joining the chain, and be sure to use the same type of link as the chain is currently made from. Once the chain is reconnected, you can reattach the chain to the bike and start pedaling again.
