Apple's newly published patent application reveals plans for a bicycle computer system similar to Nike+, which uses your iPhone or iPod as the interface. The system would include GPS routing, weather recording and communication between a group of bike riders.
The GPS and mapping capabilities offer cyclists a chance to rate and give feedback on specific routes, or view directions and topography for an anticipated path. Apple's system would also include other elements common to current bike computers such as information on the rider's distance, speed and cadence. Additionally, it would allow for integration with devices like heart rate monitors and the ability to compare yourself with others' riding characteristics, which is great for forming a group or determining if a route is right for your level.
