Web planner - Opencyclemap layer
I use web planner for my bike trips mainly (and app for navigation). It would be great to have Opencyclemap as a layer available for planning. Or maybe CyclOSM - similar, and some user might find it a better option.
These maps give you better view of cycling tracks, especially in larger scale, a lot better for quickly finding them. It makes it easier to plan your route when you have a broader view with tracks visible. Also, it helps recognize bicycle tracks from hiking ones.
