Today Google Maps has added biking directions in Germany, France, Poland, Ireland, Luxembourg and Liechtenstein.
If you search for bike directions in Google Maps you will be shown a route that avoids busy streets and uses suitable bike paths. Time estimates for bike routes on Google Maps are based on a complex set of variables accounting for the type of road, terrain and turns over the course of the route.
In the UK Sustrans has created a handy mapped guide to cycling routes. The Sustrans Cycling Map shows traffic free cycling paths and on-road cycling routes.
The map also includes the option to view bike shop locations, train & bus stations, accommodation, restaurants / cafes and museums & galleries.
allows cyclists to preview cycling routes on video before they attempt
to cycle the route for real. Cyclodeo recently added cycling route video coverage for Amsterdam.
Cyclodeo uses Google Maps and videos of a cycling route to allow the user to
view the route in a YouTube video. The videos are synced to the Google
Map of the route so that the user can click anywhere on the route and view
the video at that location.
As well as providing video bike routes in Amsterdam Cyclodeo has coverage in Copenhagen, New York, London, Paris, Berlin and Barcelona.
