Hammerhead
is a new bike navigation system that guides you to your destination
while not distracting you with text, small graphics or the need for
headphones. The sleek device attaches to your bike and wirelessly
connects to the included app on your smartphone, it will then guide you
to your destination by lighting up turn signals, and other visual
information. You can even set your preferences like hills, distance,
scenery or difficulty for a different ride experience every time. Aside
as a navigator, it also works as your bike light. watch the video
