The Hammerhead navigation tool makes bicycling a lot more fun and safe. Don’t worry about how it works. Just fix it to the handlebars and off you go. It’ll tell which way to go so that you can use the best bike routes on the way to your destination. Unlike other navigation devices, you don’t have to stop and look to get directions. The Hammerhead is right in front of your eyes, and a quick glance at it will tell you which way you need to go.
