You may not be able to pack it in your Porsche to drive to a ride, but you can look stylish on a Porsche bike. The performance auto maker just announced two bikes, the Porsche RS and S, which will be released in the fall in sizes S, M and L.
Both the RS and S bikes are 29ers, a trend in mountain bikes that uses wheel sizes similar to that on road and cyclocross bikes. The Porsche Bike S is constructed with a belt drive, which minimizes maintenance with a rubber belt in place of a chain. 
The Porsche Bike RS, which stands for Rennesport or motor racing, boasts a high-end carbon frame that offers high stability and a good deal of damping properties. The newly-developed modular monocoque construction lends itself to some of those dampening abilities. RS comes with a 20-speed Shimano XTR gear system and 29-inch Crank Brothers wheels. None of that weighs down the bike, but Porsche weight-optimized with features like the carbon brake levers.
The Porsche Bike S has a high-performance aluminum 7005 frame, which improves rigidity while providing rider comfort. The toothed belt drive system and 11-speed Shimano Alfine IGH minimize slippage and make shifting easy for the rider. The latest generation of hydraulic Magura disc brakes allow for braking in wet or dry conditions. The S also features 29-inch wheels with tires optimized for rolling and road holding characteristics.
