So, if you use this think, are you cycling or walking or running? How often do you need to change the tires? Very cool!

TreeHugger loves promoting walking and bicycling, so, of course, we love the Walking Bike. And if the human-powered transportation angle wasn’t enough, there’s some pretty serious shoe recycling going on here, too. As our pals at Gizmodo say, “it’s quite possible the greatest invention ever.” Hit the jump to see someone riding (or should we say “walking”) this thing. Hmm. Maybe we’ll stick to just one or the other. ::Arkitip via
