When a car manufacturer unleashes a bike on customers, it is not uncommon for the two-wheeler to be more of an accessory than a serious piece of mobility or sports equipment. However, there is nothing to complain about when it comes to the brand new e-mountain bike that is rolling onto the market under the Porsche banner. No wonder - because with Rotwild, Magura, Shimano and Crank Brothers, there are also some big names on board.
