The handsome Riese & Muller Supercharger Bike sports a supermodel structure thanks to an unusually slinky—for an e-bike—battery built by Bosch, good for up to 1,000 watt-hours and housed within the bike’s frame. There are a couple of high-speed touring options available that peak at 20- and 28mph, with options for super- suspension and off-road tires to kick that adventuring up a gear.
