EV powertrain. It has a traditional Japanese design with motorcycle-derived innards but a cushy (and tackily upholstered) back seat for two -- or maybe three depending on how friendly everyone is. The side curtains are made of bamboo and washi paper, giving it a look that says "I'm at least partially organic." It's available now for a mere ¥100,000; about $1,200.
Update: A little further Googling has found a number of prior permutations for gas-free rickshaws, including a solar model, making us think the "world's first" claim here is perhaps a little dubious -- as it often is. Still, we'll give it world's first mass produced EV rickshaw.
