Put German car engineering to the service of cycling and this is what you get: The Porsche Bike RS ($5,900). Just like Audi is doing with electric bikes, Porsche is doing with mountain/hybrid bikes. The Porsche RS is a 20 gear (Shimano) bicycle, with a lightweight, monocoque carbon frame that only weights about 19lb. The bike is also equipped with advanced features and accessories such as ergonomic handlebars, and 29-inch Crank Brothers wheels.
