Power-Folding: It's the world's first power-folding stroller: at the touch of a button, it folds itself. To open or close the stroller, just push that button and relax while the rest takes care of itself. Built-in Generator: Products for kids consume millions of alkaline batteries each year, and we didn’t want to add to that total. The Origami has built-in generators so the system recharges itself while you walk. Sure, you can plug it into a wall or even fold it manually if you need to, but a short walk is all it takes to keep the battery fully charged. It’s hard to be greener than that. Safety: We’ve heard it before: won’t it eat my baby? Never fear: the Origami’s strictly vegetarian. Built-in sensors means it won’t fold a child in the seat, and the two-step activation system means you won’t fold it by accident. Plus, the Origami has daytime running lights to keep it visible at all times, and pathway lights to brighten your way in low-light conditions. LCD Screen: The LCD interface makes the Origami so easy to use our grandmothers can do it (no offense, Grandma). Plus, the Origami knows things. All you have to do is look at the display to confirm it knows a child is in the seat, or how charged the battery is, or how far you’ve walked. Easy, convenient, and very cool.
