Obesity in children has become an increasingly apparent concern over here in the United States. That's probably because we don't have one of these pedal-powered school buses taking our kids to school. Made by the Netharlands' De Cafe Racer, this child-powered vehicle brings an eco-friendly approach to encouraging kids to exercise. The teacher simply has to steer in the right direction while all of the children wear their sugar-filled hyperactive bodies out.Okay, maybe this bike-bus thing isn't a school bus after all, but it does come in that iconic yellow color! Rather than a transport vehicle for school kids, this vehicle is actually a rental that can be used for a day of fun. But a bright idea such as this one could definitely be worthy of some attention here in the U.S. or other areas with notable obesity.
