OKAI has unveiled the Ranger, a new fat-tire e-bike. The pedelec is billed as a cheaper, all-terrain bike, with 4-in thick tires for extra comfort when off-roading. The bike has a top speed of 28 mph (~45 kph) and can travel up to 45 miles (~72 km) on a single charge. Plus, you can use the built-in touchscreen and accompanying app to configure the bike's settings.
