Last thing I'll lift from Treehugger this weekend, I swear. The Triobike is a Danish transport system that is a bike, a stroller/pram, and a bike-stroller-pram all in one. The large sidecar-looking pod fits on the front of the bike, allowing you to pedal around with 1-2 children in it, or you can use it to transport gear, groceries, whatever. But it also functions as a stand-alone bike and wheelbarrow/stroller. While it looks very simplistic, apparently the internal Shimano gears and brakes are quite sophisticated. Which is good, because it costs $2,450. Which would've sounded like a lot last week, but ends up equalling about 15 fillups for a Lincoln Navigator.
