Well, a while back my chain broke off my BMX bike. I just heard recently that you can make a mountain bike chain into a BMX bike chain. Is this true? And if so, can you please give me a guide on how to do so? I know it would be alot easier to go and buy a new chain but I don’t want to.

Mountain bikes use a 3/32 inch chain and BMX bikes use a 1/8 inch. Go to Walmart and buy a new chain for $10. You will need to get a chain breaker while you are there $6.
