Daily commute a drag? Take a cue from pedal-mad Amsterdam and test drive Puma's new ride. Made in collaboration with Danish manufacturer Biomega and streetwear brand Vexed Generation, the lightweight, one-speed bike features a built-in lock that renders clunky chains obsolete. And its folding mechanism simplifies storage in even the tiniest studio apartmentor car trunk, should you want to hit the open road. What's more, its upright seating style means you don't have to be Lance Armstrong (or sport spandex) to pick up some groceries.
