Few sights are more ludicrous than a rider on a foldable bike. Tiny wheels, tall seat, and full-size human, this crudely proportioned mess pedals furiously down the street like it’s just escaped from some child’s drawing. The bikes’ folding virtues offer few favors, as sweating brows, grease-stained pants, and half-collapsed bikes are fixtures at recently vacated subway platforms. Enter the E-Cyclopic, an upcoming e-bike that promises to restore the cycling commuter’s dignity. A spoke-less design allows the rear wheel to fold neatly within the front, the solid tires are puncture-proof, and the internal drive mechanisms draw intrigued, not rolled, eyes. (cyclopic.co.uk)

Narcos isn’t the only television series that takes a hard, hypnotic look at Latin American corruption. The Candidate is a political thriller based on the real-life assassination of Luis Donaldo Colosio, a reform-minded politician who was killed while campaigning for president in 1994. The authoritarian government of President Carlos Salinas hastily closes the case, so Colosio’s young widow, Diana Laura, investigates the murder herself. She has many high-placed friends, but the only person she trusts is an out-of–favor provincial police detective who also smells a cover-up. (Watch on netflix.com.)
