<human>:  How do I fix a broken bike chain?
<bot>: 
1. First, you will need to remove the chain from the bike. To do this, you will need to open the master link, which can easily be done with a screwdriver or hex wrench.
2. After removing the chain, you will need to clean and inspect it. Clean with a degreaser and check for any broken or twisted links.
3. Next, you will need to find the new chain that most suits your bike. Make sure to purchase a chain that is the correct length, width, and speed for your chainring and cassette.
4. After you have your new chain, you will need to install it. Start by feeding one end of the chain through the derailleur and chainring. Then, put the missing link through the cycle and follow the direction of the chain.
5. Finally, use a chain tool or chain press to close the master link or rivet. Finally, check to ensure that the chain is properly aligned and securely attached.
