Gadget Ogling: Smart Bikes, Contactless Cards, and Roll-Up Keyboards

I never had much interest in riding a bicycle as a child, and although I now live in a tremendously bike-friendly city, I haven't found a way to learn without feeling like a total chump in public. Yet I am more interested than ever in leading a life on two wheels after discovering SmartHalo. This is a tool that attaches permanently to one's ride and turns it into a smart vehicle. The "halo" part of that name refers to the circular display, which uses color and segmented lights to indicate turn-by-turn directions.
