OpenCycleMap, based on OpenStreetMap, is another resource you might consider. www.skobbler.us is usefull as an app on a smart phone. It does not only provide car routes but also for bike and pedestrian. But both are basically maps, not so much suggestions where to ride.

OpenCycleMap, based on OpenStreetMap, is another resource you might consider. It uses a Creative Commons Attribution-Share Alike license, which is why many of the mobile applications actually use the OpenCycleMap data. Anyone can register and contribute to OpenCycleMap, so in that sense it is like Wikipedia, in that it is often more up-to-date. Just looking at OpenCycleMap is much easier than a Google Map for instance, because the cycle routes are clearly marked.
