How can I fix a snapped chain on a bicycle?

To fix a snapped chain on a bicycle, you will need to remove the broken chain and replace it with a new one. You will also need a chain tool to help with this process. First, remove the broken chain by using the chain tool to push out the pin holding it together. Then, thread the new chain through the derailleur and around the gears, making sure it is the correct length for your bike. Finally, use the chain tool to push the pin back into place to secure the new chain.
