Cycle Map

OpenCycleMap is a OpenStreetMap rendering layer like the standard tile layer, but primarily aimed at showing information useful to cyclists. The website provided by Andy Allan is little more than a way of viewing the map, but the tiles are used in a number of other websites and applications. The layer can also be seen on the main OSM page by selecting the "cycle map" layer.

The map rendering is still being improved, and is updated on average about every two weeks.

It shows National Cycle Network cycle routes, other regional and local routes, and other cycling-specific features, such as:

  • dedicated cycle tracks and lanes
  • bicycle parking
  • contours and hill colouring
  • bike shops, toilets, drinking fountains, even pubs!
  • proposed bike routes (or numbering protocols), contrasted with the Lonvia map, below, which does not show proposed routes, but actual routes only
  • contraflow using oneway:bicycle=*. cycleway:left=* and cycleway:right=* also rendered

Update cycle

The database (as of May 2010) is updated using diff updates, and on average is updated about every two weeks.

While the database could be updated more frequently than that (it has run hourly, in the past), there is always a huge backlog of tiles that need refreshing. Refreshing the tiles takes a few days. The system is self-correcting in that the more popular the tile, the sooner it gets refreshed. But lower zoom levels (5 to 9) may be kept frozen for longer periods.

Contact info / Reporting problems

Bugs and requests are taken via email to support, “ат”thunderforest (dot) com. Old tickets are available from the OpenStreetMap Trac system at

When reporting, please verify that it's really a rendering issue first: use the data layer and compare with other background layers.

For general questions or anything else please email Andy Allan using the address on in the first instance.


Andy spoke at State Of The Map 2008 regarding the cycle map, and a video and slides are available from that page.
