Use at your own risk. Routers are a can of worms and rarely give perfect results. This router depends on the "ways" in Open Street Map being connected at both ends. In many cases they are not, especially for the off road paths - see this link. Hit the "Start routing" button and drag the A to B markers around to suit. You cannot click on any other markers while routing, so turn off routing before clicking on any other icons that may be of interest to you.
Time by Bike
You can use the Time by Bike layer to estimate travel times at different speeds. You can lock the rings centered on say your home location or have them track the map center. Click on the central icon to access the controls for Time by Bike.
Use the controls on the left to zoom and pan the map. Use the Layer Switchers on the right hand side to select different maps and overlays. Most icons on the map will show further information when clicked on.

On some layers the information displayed or the visibility of the information depends totally on the current Zoom level.
In most browsers the F11 key can be used to enlarge and contract the map.
This site can be slow and is probably unusable with slow internet connections or old browsers. Some layers can take seconds before they are drawn. However things change.
