Porsche, the famous German car company, has unveiled two human-powered innovative city bikes for 2012, one of which is the Bike S. With a 7005 hydroformed aluminum frame, the Bike S is designed by Porsche to ride with amazing comfort, enhanced rigidity, and excellent performance be it for tours or city rides.
Constructed based on a Shimano 11-speed Alfine hub gear system, which is internally geared, the Bike S features a double-clutch gear shift system as well as high-quality disc brakes from Magura. The Shimano Alfine 11-speed hub comes with a Gates belt, too.
Though equipped with several topnotch components, the 2012 Porsche Bike S City Bike only weighs in at 11kg. These high-quality components also include carbon fiber front forks and DT Swiss wheels, which are fitted with resistance tires for smooth rolling. It will be available in three sizes.
