A New Bike With Buzzing Handlebars That Give You Directions

You could buy two such full featured smart watches and it'd probably still be cheaper and less maintenance than building it into the bike. Actually, the dev kit for Glass could well be cheaper too.

As a bike rider, I'm not sure why these bike design things get so viral. Is it like food shows where people who don't cook watch people making impractically extravagant dishes?

Obviously, but enough to base their bike purchase around that aspect? Most people I know who ride a lot and spend up on their bikes use them primarily for commuting (they know the route) or exercise (know the route or are riding with friends who know). Again, sample set is just those I know, but they still drive if they're heading to a meeting or event at a new location.
