At least once in your lifetime, you will encounter a hill—nay, mountain—whose sole purpose is to thwart your determination to reach your destination. It is the probability that this foreboding mountain lies in your future path that makes the Wind-Solar Energy Bike so special. (To which you reply: Don’t you mean because of its eco-friendliness? No, my friends, I don’t.)
Unfortunately, the Wind-Solar Energy Bike is still a concept, created by Chen Chun Tung. “Specially designed in a compact manner,” Tuvie reports, it “can convert various natural power sources into electric power when the user rides it.” So that, by the time the going truly gets tough, all you need to do is switch to the electric riding mode and that hill doesn’t seem so mountainous anymore!
