Journalists try to ride an electric motor-assisted standing-style tricycle called the "Walking Bicycle", produced by Japan's auto parts maker Katayama Kogyo, during a press preview in Tokyo on April 30, 2014.  The new style vehicle can travel a maximum speed of 24 kph (15 mph), assisted with an electric motor when the user steps on the pedals like walking. The company will put it on the market in July with a price of 3,000 USD.    AFP PHOTO / Yoshikazu TSUNO        (Photo credit should read YOSHIKAZU TSUNO/AFP/Getty Images)
