Using the PDW Alexander Graham Bell is super easy. Just install it by replacing a 10mm headset spacer on your bike. Once it's on, give it a little ring whenever you need to let others know you're coming. When it comes to maintenance, since it's made of solid brass, it's quite durable. But to keep it looking shiny, you can use a brass cleaner every now and then. Also, make sure to check the installation periodically to ensure it's still firmly in place. If you notice any rattling or looseness, just tighten it up. And that's all there is to it! Enjoy using your new bell.
